A U-shank jigsaw blade set can save an otherwise useful older jigsaw from sitting idle, but the shank is only the first checkpoint. Buyers also need a sensible mix of tooth counts, material guidance, blade quantity, and storage. A set with plenty of blades may still disappoint if most of them are duplicates or if its tooth patterns do not suit the wood, plastic, or metal on the workbench.
The supplied choices range from compact 10- and 12-piece assortments to large 50- and 54-piece cases. Their advertised TPI ranges differ, too. Lower tooth counts are generally positioned for faster wood or plastic cuts, while higher counts are listed for finer cuts and thin nonferrous metal. Compatibility deserves equal attention. A U-shank blade must match the jigsaw’s blade holder, and a broad “fits most” statement should not replace checking the tool manual or clamp design.
This comparison weighs documented shank type, tooth-count variety, stated material applications, storage, and the usefulness of each assortment for real projects. The Craftsman set earns the strongest overall position because its listed applications include fast, down-cut, scroll, wood, and metal options with stated thickness ranges, while Bosch and Lenox offer more focused alternatives for buyers who prefer established blade kits.
Quick Answer
The CRAFTSMAN CMAJ2SET12 is the best overall choice for shoppers who want a compact U-shank assortment with clearly identified wood, scroll, down-cut, and metal applications. The BOSCH U12BC is a strong pick for mixed wood and thin-metal work, while the 54-piece U-shank set suits busy users who want multiple replacements across seven listed tooth counts. For a smaller general-purpose assortment, the LENOX 1994459 adds a hard case and documented wood-cutting focus.

The detailed reviews below separate compact specialty assortments from larger replacement cases, with special attention to the materials and tooth counts each listing actually documents.
1. CRAFTSMAN Jigsaw Blades, U-Shank Set, 12-Piece – Best Overall
The Craftsman set stands out because its listing explains what several blade types are meant to do rather than giving shoppers only a tooth-count range. The 6 TPI fast-cut blades are listed for material from 1/4 inch to 1-7/8 inches, while the 10 TPI down-cut and wood blades cover thinner stock. That makes the assortment easier to sort beside a stack of plywood, trim boards, or a plastic panel.
There is also a dedicated 12 TPI scroll option and two metal options listed at 14 and 24 TPI. The stated metal ranges are specific, with the 14 TPI blade listed for 3/32-inch material and the 24 TPI blade for 1/8-inch material. Those details do not guarantee a particular edge finish, but they give buyers more useful starting guidance than a vague general-purpose label.
Pros
- Clearly documented U-shank assortment.
- Includes fast-cut, down-cut, wood, scroll, and metal options.
- Lists material thickness ranges for several blade types.
- Useful mix for wood and metal projects.
- Compact 12-piece format is easy to organize.
Cons
- Smaller assortment than the 30-, 50-, and 54-piece kits.
- Listed metal applications are limited to specified thin material ranges.
This is the strongest match for a homeowner or repair-minded user who wants meaningful variety without a crowded case. It is also a practical starting point for anyone uncertain about which tooth count belongs on a jigsaw. Buyers who routinely cut many sheets of material may prefer a larger replacement-heavy set, but the Craftsman kit offers the clearest application guidance in this group.

2. BOSCH U12BC 12-Piece U-Shank Assorted Set – Best for Thin Metal and Wood
Bosch positions this 12-piece kit around two useful jobs: common wood cutting and thin-metal cutting. The listing identifies high-carbon steel construction, high-speed steel teeth, and a flexible steel spring-back design. Those descriptions give the set a more specific identity than an anonymous mixed pack, particularly for a toolbox that occasionally moves from a wood panel to thin sheet material.
The assortment also includes clean, fast, and scroll wood applications. That spread matters in a small kit because a user can select a blade according to the desired cut rather than treating every blade as interchangeable. The listing says the U-shank design is compatible with U-shank jigsaws, so buyers should still confirm their machine uses that holder before ordering.
Pros
- Documented U-shank design.
- Includes wood and thin-metal applications.
- Uses high-carbon steel with high-speed steel teeth.
- Includes clean, fast, and scroll wood categories.
- Flexible steel construction is listed as a life-extending feature.
Cons
- Only 12 blades are included.
- Thin-metal use is more specialized than a broad heavy-material assortment.
The Bosch kit fits users who value a focused assortment from a recognizable blade maker and expect occasional thin-metal work. It is less compelling for a contractor who needs many replacements of each tooth type. Its appeal is the balance between a manageable case and clearly stated wood and metal roles.

3. LENOX TOOLS 1994459 U-Shank General Purpose Kit – Best for Clean Wood Cuts
Lenox takes a narrower approach with this 10-piece kit. Its listed strengths center on wood, where precision-ground teeth and optimized tooth angles are described as supporting a clean finish. That focus may appeal to someone cutting shelving, trim, or project panels who would rather have a concise general-purpose case than dozens of loosely categorized blades.
The kit also lists Power Blast technology, which the product information associates with reduced breakage and greater durability. A hard case adds a practical advantage for keeping a few blade types from rattling around in a drawer.
Pros
- Documented U-shank general-purpose design.
- Precision-ground teeth are listed for clean wood cuts.
- Optimized tooth angles are part of the stated design.
- Power Blast construction is intended to reduce breakage.
- Includes a hard case.
Cons
- Ten-piece capacity is modest.
- The product specifications emphasize wood rather than a broad material range.
Lenox is the sensible selection for woodworkers who place cut finish and organized storage above maximum blade count. It is less suitable as a one-box solution for frequent metal and plastic work because the available information does not document the same breadth of applications shown by several other sets. Verify the jigsaw’s U-shank requirement before purchase.

4. 54-Piece U-Shank Jig Saw Blade Set – Best for Frequent Replacements
A 54-piece case makes sense for a busy workshop where blades disappear into offcuts, tool bags, and half-finished repairs. This set divides its contents across seven listed tooth counts: 6, 8, and 10 TPI for wood and plastic, plus 14, 18, 24, and 32 TPI for metal or nonferrous metal applications. The blades are also marked with their corresponding TPI, which can make selection faster when the case is open beside the saw.
The product information identifies high-carbon steel construction and lists compatibility with many major jigsaw brands, including Bosch, BLACK+DECKER, Craftsman, SKIL, DeWalt, and Milwaukee. That is a broad seller-provided compatibility claim, not a substitute for checking the individual saw. The storage box and repeated blade quantities make this a replacement-oriented option rather than a small sampler.
Pros
- Largest documented assortment among the selected U-shank sets.
- Seven listed TPI categories.
- Separate tooth ranges are described for wood, plastic, metal, and nonferrous metal.
- High-carbon steel construction is specified.
- Storage box and marked TPI support organization.
Cons
- Many blades may be unnecessary for occasional DIY use.
- Compatibility still requires checking the specific jigsaw holder.
This set is a strong fit for installers, maintenance users, and project shops that prefer keeping replacements on hand. Someone who cuts only occasional wood curves may find the assortment excessive, while a user working across furniture installation, plastic, and thin metal can make better use of its spread. Match the tooth count to the material instead of choosing by blade quantity alone.

5. 30-Piece U-Shank Jig Saw Blade Set – Best Portable Mixed-Material Kit
This 30-piece assortment sits between a compact household kit and a large contractor case. Its listed applications cover wood, plastic, and metal, with 6, 8, 10, 14, 18, 24, and 32 TPI represented. That range gives a user a sensible way to move from rougher wood work toward finer cuts or thin metal tasks without carrying a separate case for every material.
The product title identifies compatibility with Bosch, DeWALT, SKIL, and Black+Decker U-shank jigsaws, and the set includes a 420D zipper bag. The product specifications do not provide a per-tooth-count quantity breakdown, so buyers should view it as a broad portable assortment rather than assume equal coverage of every category.
Pros
- Thirty-piece quantity provides useful spare capacity.
- Seven listed TPI categories cover varied tasks.
- Advertised for wood, plastic, and metal cutting.
- Includes a 420D zipper bag.
- Product title identifies several compatible U-shank tool brands.
Cons
- Check how many blades belong to each TPI for the exact product configuration.
- Brand compatibility should still be confirmed against the individual tool.
The zipper bag makes this a good choice for a mobile tool tote, especially for a user handling small repairs at different locations. It offers more replenishment than a 10- or 12-piece kit without reaching the bulk of a 54-piece box. Buyers who need exact blade counts for repeated metal work may prefer a set with a published breakdown.

6. 50-Piece Contractor U-Shank Jigsaw Blades Set – Best Large Workshop Assortment
The 50-piece contractor set is aimed at users who want a generous supply of assorted blades in one storage case. Its title identifies HCS and HSS construction, wood, plastic, and metal applications, plus 6, 8, 10, 12, 20, and 21 TPI choices. That selection differs from the more common 14-to-32 TPI spread found in several other sets, so it may suit shoppers whose work aligns with these listed categories.
Because the product details do not provide a detailed count for each tooth type, the headline quantity should be read as total inventory rather than proof of broad equal coverage. Still, a case of this size can be convenient for a shared workshop, where one user may need a replacement after a rough cut and another may need a finer option later the same day.
Pros
- Fifty-piece U-shank assortment.
- Lists HCS and HSS blade construction.
- Advertised for wood, plastic, and metal.
- Includes six documented TPI categories.
- Storage case supports workshop organization.
Cons
- The available data does not identify the quantity of each blade type.
- Its TPI range differs from sets that extend to 32 TPI for finer listed cuts.
This set is best for a workshop that values inventory depth and does not need a narrowly defined specialty assortment. It is a less transparent choice for someone trying to match an exact tooth count to a specific metal thickness, since the listing data is limited. Confirm the case contents and the jigsaw’s U-shank holder before starting a project.

7. OSVJE 14-Piece U-Shank Jig Saw Blade Set – Best TPI Variety in a Compact Set
OSVJE packs two blades at each of seven TPI levels: 6, 8, 10, 14, 18, 24, and 32. The even two-per-category layout is useful because it provides a spare when a blade is worn, bent, or left in another toolbox. The listing assigns the lower three counts to wood and plastic, 14 TPI to medium metal cutting, and the higher counts to nonferrous metal applications.
The high-carbon steel construction and stated U-shank format make this a straightforward mixed-material assortment. The product information also mentions thin copper sheet and PVC among the intended uses. Those applications should be treated as listed guidance rather than a promise that every blade suits every thickness, but they do help define the set’s intended range.
Pros
- Fourteen blades are evenly divided across seven TPI levels.
- Includes both fast wood/plastic and fine metal-oriented options.
- High-carbon steel construction is specified.
- Thin copper sheet and PVC are listed applications.
- Compact quantity includes a replacement for each tooth category.
Cons
- Only two blades are supplied at each TPI.
- Material suitability remains dependent on workpiece thickness and tool compatibility.
This is a useful pick for a DIY user who wants a predictable sample of each listed tooth count. It avoids the mystery of a large mixed box, though a contractor cutting the same material repeatedly will use up the two matching blades sooner. The 32 TPI options are especially relevant to shoppers seeking a finer listed metal-oriented choice, provided the workpiece matches the blade’s intended use.

8. 14-Piece U-Shank Jig Saw Blade Set – Best Compact General-Purpose Set
This set uses the same practical two-blade-per-category structure across 6, 8, 10, 14, 18, 24, and 32 TPI. The product information describes high-carbon steel blades for wood, plastic, and metal, with the lower counts intended for faster work and the higher counts positioned for finer cutting. For a small household toolbox, that is a simple selection system that does not require sorting through dozens of nearly identical pieces.
The listing describes the blades as fitting a vast majority of U-shank jigsaws. That wording is broad, so the actual holder on an older or unusual machine remains the deciding factor. The set is best understood as a basic mixed-material supply, rather than a specialized kit for a particular metal, curve radius, or finish requirement.
Pros
- Includes seven useful TPI categories.
- Two blades are supplied at each listed tooth count.
- High-carbon steel construction is documented.
- Advertised for wood, plastic, and metal.
- Simple format suits occasional household projects.
Cons
- Does not document specialized blade geometry beyond the TPI range.
- Broad compatibility wording should be checked against the jigsaw model.
This compact set makes sense for a homeowner who wants a few options for shelves, craft panels, plastic, and light metal tasks. It may be too limited for a professional who needs many replacements or a blade engineered for one demanding material. Its appeal is the tidy spread of common tooth counts, not a deep supply of any one blade type.

9. EupHHonycs 14-Piece Universal U-Shank Blade Set – Best Balanced DIY Assortment
EupHHonycs offers another evenly divided 14-piece set, with two blades each at 6, 8, 10, 14, 18, 24, and 32 TPI. The listing identifies high-carbon steel and applications across wood, plastic, and metal. That combination gives a beginner a clear progression from faster, coarser work toward finer listed options without requiring a separate wood-only and metal-oriented purchase.
The product description refers to a vast majority of U-shank jigsaws and also uses broad compatibility language. Buyers should read that as a general fit claim rather than universal proof, especially if the machine uses a less common clamp. The inclusion of several tooth counts makes the set flexible, but the product details do not document blade dimensions or exact thickness limits.
Pros
- Fourteen blades cover seven TPI categories.
- Two pieces are supplied at each listed count.
- High-carbon steel construction is stated.
- Advertised for wood, plastic, and metal.
- Useful introduction to mixed-material blade selection.
Cons
- Exact blade dimensions and thickness limits are not supplied.
- Broad compatibility claims require confirmation with the actual jigsaw.
This set is a reasonable choice for a new jigsaw owner building a basic blade drawer. It offers enough variety for common repair and craft jobs, though a user cutting thick stock or demanding a particular edge finish will need more specific manufacturer guidance. Its close similarity to other 14-piece assortments means buyers should compare fit, storage, and current listing details rather than assume the label alone makes it superior.

Buying Guide
Confirm the U-Shank Holder
U-shank blades use a different interface from T-shank blades. A blade can look close enough in a product photograph yet fail to lock into the tool’s clamp. Check the jigsaw manual, the blade-holder shape, and the model-specific compatibility information before ordering. A listing that says “fits most” is helpful, but it does not remove the need to verify an older machine.
Confirm T-shank versus U-shank compatibility before ordering a replacement for an unfamiliar blade clamp.
Match TPI to the Material and Cut
The selected sets use lower counts such as 6, 8, and 10 TPI for faster wood or plastic work, while higher counts such as 18, 24, and 32 TPI are commonly listed for finer cuts or nonferrous metal. Tooth count alone does not determine the result. Material thickness, blade geometry, feed pressure, and workpiece support also matter. Use the manufacturer’s stated application as the starting point.
Read Material Claims Precisely
“Metal” is a broad label. Some listings specifically mention thin metal, copper, aluminum, or nonferrous metal, while others simply name metal among several applications. Do not assume that a general metal blade is intended for stainless steel or thick steel. The Craftsman and Bosch sets provide more specific application information than several generic assortments, which makes them easier to match to a defined task.
Choose Quantity Based on Replacement Needs
A 54-piece case is useful when several people share a toolbox or when blades are consumed regularly. A 10-, 12-, or 14-piece kit is easier to sort and may be sufficient for occasional shelves, trim, and craft work. Large counts can include many duplicates, so inspect the breakdown of tooth types rather than judging the case by total quantity alone.
Check Blade Length and Workpiece Thickness
The product details do not provide complete blade dimensions for every set. Do not assume that every blade in an assortment has the same usable length or suits the same thickness. A blade must have enough working length for the material and the jigsaw’s stroke. For thick stock, consult the blade maker’s application guidance and avoid transferring a thin-material recommendation to a deeper cut.
Separate Fit From Cutting Suitability
A U-shank blade may physically fit a jigsaw and still be wrong for the job. A coarse wood blade is a poor choice for thin sheet metal, while a fine metal blade may be slow or unsuitable for a thick wood cut. Keep a few clearly labeled categories in the case so the blade selection does not become guesswork halfway through a project.
Best U-Shank Jigsaw Blades FAQ
What is a U-shank jigsaw blade?
A U-shank blade has a U-shaped mounting end intended for compatible jigsaw holders. It is an interface standard, not a guarantee that the blade fits every jigsaw. Check the tool’s manual or clamp before purchase, especially with older machines.
Can U-shank blades fit a T-shank jigsaw?
Do not assume they can. T-shank and U-shank systems use different mounting shapes, and compatibility depends on the specific jigsaw holder. Choose a blade type documented for your tool rather than relying on a similar-looking base.
Which TPI is best for wood?
The answer depends on material thickness and the desired cut. In the supplied sets, 6, 8, and 10 TPI options are listed for wood or plastic applications, while some 10- and 12-TPI blades are positioned for smoother or scroll work. Follow the blade maker’s material guidance and support the workpiece securely.
Can these U-shank sets cut metal?
Several sets list metal applications, but the recommendations differ. Craftsman documents 14 and 24 TPI metal options with specific thin-material ranges. Bosch identifies thin-metal blades, while the larger mixed sets list metal or nonferrous metal use. Do not treat every blade in a mixed pack as suitable for every metal.
Are high-carbon steel blades durable?
High-carbon steel is the documented construction for several sets, and the listings describe it as wear-resistant or durable. That does not establish a fixed service life. Blade life depends on the material, thickness, feed pressure, cutting heat, and whether the blade is used for its intended application.
Is a larger blade set automatically better?
No. A larger case provides more replacements, but a smaller kit may offer clearer selection and less storage clutter. Compare the number of distinct TPI categories, material guidance, storage, and the quantity of blades you actually expect to use.
Can one blade cut wood, plastic, and metal?
Some assortments contain blades for all three materials, but that usually means different blades within the set. Select the blade marked or described for the material being cut. A blade that fits the tool is not automatically appropriate for every workpiece.
Final Verdict
The CRAFTSMAN CMAJ2SET12 is the best overall selection for Best U-Shank Jigsaw Blades because its compact assortment provides the clearest application map. Fast-cut, down-cut, wood, scroll, and metal categories are identified, and several material thickness ranges are listed. That information helps a homeowner make a sensible choice at the workbench instead of sorting through a box based only on tooth count.
Bosch is the stronger alternative for buyers focused on common wood work and thin metal, while Lenox suits users who prefer a smaller wood-oriented kit with a hard case and documented clean-cut design. The 54-piece assortment is the practical choice for frequent replacements. Whichever set you choose, verify the U-shank holder first, match TPI and material guidance to the workpiece, and treat broad compatibility claims as a prompt to check the exact jigsaw model.
