Product Description
CMT JT144D Jig Saw Blades - Wood/Coarse Straight, HCS, 4" x 6 TPI (25-Piece Pack) by CMT are high-carbon steel jig saw blades engineered for very fast, straight, and coarse cuts through hardwood, softwood, plywood, and OSB. With a 6 TPI tooth count and a 4 mm tooth distance, these blades rip through material from 7/32 in. to 2-3/8 in. thick with aggressive speed - making them an ideal choice for production cutting, framing work, and plunge-cut applications where throughput matters.
Key Features
- High-Carbon Steel (HCS) Construction - delivers fast, aggressive cutting performance through hard and soft woods, plywood, and OSB, maintaining a sharp edge across high-volume cuts.
- 6 TPI Coarse Tooth Configuration with 4 mm Tooth Distance - optimized for very fast straight cuts, removing material quickly and keeping the blade clear of chips during extended use.
- 4 in. Total Length / 3 in. Cutting Height - provides a practical cutting reach suitable for boards, panels, and sheet goods up to 2-3/8 in. thick.
- Universal T-Shank Design - compatible with all major jig saw models without an adapter, so these blades drop right into your existing cordless or corded jig saw.
- Plunge Cutting Capability - allows starting cuts in the middle of a workpiece without a pre-drilled entry hole, expanding the range of cuts you can make without additional setup.
- 25-Piece Pack - stocked in quantity for production environments, job-site crews, and shops that need a reliable supply of blades on hand.
- Wide Material Thickness Range (7/32 in. to 2-3/8 in.) - covers everything from thin plywood and OSB panels to thick hardwood and softwood stock in a single blade selection.
Why This Product
- When job-site speed is the priority, the 6 TPI coarse geometry delivers very fast straight cuts through hardwood and softwood up to 2-3/8 in. thick - reducing passes and keeping production moving.
- The universal T-shank fits all major jig saws, so these blades work with the tools already on your job site or in your shop - no adapters, no compatibility guesswork.
- Plunge cutting support means you can start interior cuts without pre-drilling, saving setup time on sheet goods, plywood, and OSB panels.
- The 25-piece bulk pack is sized for production use - keeping a full supply of replacement blades on hand reduces downtime when blades wear through on high-volume cutting tasks.

Frequently Asked Questions
What type of shank do these jig saw blades use?
These blades use a T-shank (universal T-shank) design, which is compatible with all major jig saw brands - both corded and cordless - without requiring any adapter.
What material thickness range can the CMT JT144D handle?
These blades are rated for material thicknesses from 7/32 in. to 2-3/8 in., covering thin plywood and OSB sheet goods as well as thicker hardwood and softwood lumber.
Are these blades suitable for plunge cuts?
Yes. The CMT JT144D is specifically listed for plunge cutting, which means you can start a cut in the middle of a workpiece without needing a pre-drilled entry hole.
Why are these blades sold in a 25-piece pack?
The 25-piece pack is intended for production use and high-volume cutting environments. Coarse 6 TPI blades cutting through dense hardwood or rough sheet goods will wear over time, and having a bulk supply on hand keeps work moving without interruption.
