Product Description
CMT JT144D Jig Saw Blades - Wood/Coarse Straight (HCS) 4" x 6TPI from CMT deliver very fast, straight, and coarse cuts through hardwoods, softwoods, plywood, and OSB - making them an ideal choice for high-volume production work, framing tasks, and rough-cut applications where speed matters. This contractor-grade 100-piece bulk pack features High-Carbon Steel (HCS) construction and a universal T-Shank design, letting you work through material ranging from 7/32 in. to 2-3/8 in. thick without swapping tools or adapters. Whether you are ripping rough lumber, trimming sheet goods, or performing plunge cuts, these blades are built to keep up with demanding job site conditions.
Key Features
- High-Carbon Steel (HCS) Construction - heat-treated HCS material provides the toughness needed for fast cutting in hardwood, softwood, plywood, and OSB, reducing blade fatigue over extended use.
- 6 TPI Coarse Tooth Pattern with 4mm Tooth Distance - aggressive coarse geometry drives very fast straight cuts, clearing chips efficiently so cuts stay clean even at high feed rates.
- Universal T-Shank Compatibility - the T-Shank design fits all major jig saw models, cordless and corded, so there is no need for adapters or brand-specific tooling.
- Wide Material Thickness Range (7/32 in. to 2-3/8 in.) - handles everything from thin plywood panels to thick hardwood stock, giving you a single blade solution across a broad range of cutting depths.
- Plunge Cutting Capability - suited for plunge cuts where you need to start an interior cutout without a pre-drilled pilot hole, expanding versatility on finish and rough work alike.
- 100-Piece Bulk Pack - large-quantity format means you always have a fresh blade ready, reducing downtime on production runs or multi-crew job sites.
- 4-Inch Total Blade Length with 3-Inch Cutting Height - proportions optimized for controlled blade flex and stable tracking during straight coarse cuts through dense wood materials.
Why This Product
- When production speed is the priority, the 6 TPI coarse tooth geometry cuts aggressively through hardwood and softwood up to 2-3/8 in. thick - fewer passes, less time per cut, more throughput per shift.
- The universal T-Shank format eliminates compatibility headaches on mixed-brand job sites, fitting all major jig saw platforms so your crew can share blades without sorting through multiple shank types.
- At 100 blades per pack, this bulk format is purpose-built for contractors, cabinet shops, and production facilities that burn through blades regularly and need a reliable supply on hand at all times.
- Plunge cutting support combined with coarse straight performance means one blade type handles both interior cutouts and through-cuts in plywood, OSB, and dimensional lumber - fewer SKUs to stock, more flexibility on site.

Frequently Asked Questions
What jig saw models are these blades compatible with?
These blades use a T-Shank design, which is a universal shank format that fits all major jig saw models - both cordless and corded - from virtually any brand, with no adapter required.
What is the maximum material thickness these blades can handle?
The CMT JT144D blades are rated for material thicknesses from 7/32 in. up to 2-3/8 in., covering thin plywood panels through thick hardwood and softwood stock.
Can these blades be used for plunge cuts?
Yes. The JT144D is specifically suited for plunge cutting, allowing you to start an interior cut directly into the material surface without requiring a pre-drilled pilot hole.
Why would I choose a 6 TPI blade over a higher TPI option for wood cutting?
A 6 TPI coarse tooth pattern is designed for very fast cutting speed rather than a fine finish. It is the right choice when production rate and throughput matter more than edge smoothness - for example, in rough framing, OSB sheathing work, or high-volume wood processing where cuts are subsequently refined or concealed.
