Jigsaw Blades HCS - High Carbon Steel, U-Shank 4"L, 10 Variable Gullet TPI, Very Clean Cut Cut - 0 Each

Bosch Jigsaw Blades U101B For Clean Wood Cuts

Bosch jigsaw blades U101B are high carbon steel U-shank blades that cut wood and wood byproducts, so you get a versatile option for jobsite and shop tasks using common sheet goods. The 4 inch length provides reach for material in the 3/16 inch to 1-1/4 inch range, matching the stated application thickness and helping maintain control through the full stroke. A 10 variable gullet TPI design manages chip clearance as you cut, which supports both cutting speed and cut quality in wood and composites. Ground teeth paired with a taper ground back create a straight, fine cut, which matters when you are following layout lines on visible parts such as cabinet sides, shelves, or trim. The blades are described as producing clean, fast cuts in wood and wood byproducts, so you can move from rough sizing to final fit with less sanding on edges.

Key Bosch U101B Blade Details For Woodwork

• The high carbon steel construction forms the cutting body, giving you a blade suited to wood and wood byproducts where toughness and a keen edge support repeated cuts on sheet material.
• The U-shank design matches jigsaws that accept universal shank blades, so the blades sit securely in compatible tools and allow straightforward blade changes during repetitive cutting.
• The 4 inch length and application range of 3/16 inch to 1-1/4 inch material thickness align blade reach with common plywood, OSB, and laminated particle board jobs in cabinet and casework builds.
• The 10 variable gullet TPI pattern regulates tooth spacing, helping control chip flow in hard and soft woods so cuts stay efficient while limiting excessive tear at the surface.
• The ground teeth and taper ground back shape the cutting profile for straight, fine cuts, which helps keep jigsaw kerfs tight and accurate when following guides or templates on finished parts.

Fit, Shank Design, And Jigsaw Mounting Use

The U-shank design on these Bosch U101B jigsaw blades interfaces with jigsaws using universal shank blades, supporting consistent clamping and stroke control in that style of tool. The product description notes that they fit Bosch models BL3230, BL3230VS, and BL3238VS, so installers working with those saws can match blade style directly to their tools. A 4 inch blade working in 3/16 inch to 1-1/4 inch material keeps the teeth engaged through the thickness without excessive overtravel, which supports smoother tracking along cut lines. The straight, fine cut type pairs well with cabinet-grade materials such as plywood and laminated particle board, where edge quality influences banding fit and visible seams.

Real-World Cutting Performance And Material Range

Where These Bosch Jigsaw Blades Work Best

These Bosch U101B jigsaw blades are identified as one of the most popular Bosch wood cutting blades for all-around use, which positions them for general shop and onsite cutting in wood and wood byproducts. The stated applications include hard and soft woods, plastics, OSB, plywood, and laminated particle board in 3/16 inch to 1-1/4 inch thickness, so a single blade type can support tasks from subcomponents to finished panels within that range. Clean, fast cuts in wood and wood byproducts reduce edge tear on plywood veneers and laminated particle board faces, supporting visible cabinet sides and shelves. The ability to cut both wood-based products and plastics within the described thickness band helps keep setups consistent when moving between case parts, backers, and light plastic components. A straight, fine cut type supports layout-driven work such as cutouts or notches where a narrow, accurate kerf guides later fitting.

Design Details Supporting Consistent Cut Quality

The high carbon steel body on these Bosch wood cutting jigsaw blades provides the structure for ground teeth, which can be sharpened to a precise profile for controlled cutting in wood, OSB, and plywood. The 10 variable gullet TPI tooth design varies spacing between teeth, influencing chip removal so the blade can maintain speed while working toward a very clean cut description in wood and wood byproducts. Ground teeth combined with a taper ground back help the blade track along a line with reduced side friction, which supports straight, fine cuts that are important when parts must align tightly in assemblies. The U-shank format holds the blade in jigsaws that use universal shank blades, so the reciprocating motion transfers effectively into the teeth for predictable performance. Described as efficient and economical for professional or DIY users, these attributes combine to support repeated cutting on common cabinet and woodworking materials within the stated thickness range.
