Product Description
CMT JT144D-5 Jig Saw Blades - Wood/Coarse Straight (HCS) 4" x 6 TPI are high-carbon steel jig saw blades engineered for very fast, straight, and coarse cuts through hardwood, softwood, plywood, and OSB ranging from 7/32" to 2 3/8" thick. This 5-piece set delivers reliable performance for demanding wood cutting applications including plunge cutting, making them a practical choice for contractors and woodworkers who need speed and efficiency across a wide range of lumber thicknesses.
Key Features
- High-Carbon Steel (HCS) construction - provides durability and aggressive cutting performance in both hard and soft wood materials, allowing fast material removal without premature blade wear.
- 6 TPI coarse tooth configuration with 4mm tooth distance - delivers very fast cuts through hardwood, softwood, plywood, and OSB, reducing cutting time on large or thick workpieces.
- Universal T-Shank design - fits all major jig saws without an adapter, making these blades a versatile drop-in solution for most cordless and corded jig saw models.
- 3" cutting height with 4" total blade length - optimized for material up to 2 3/8" thick, giving the blade enough working length to clear chips and maintain a clean, stable cut.
- Plunge cutting capability - allows starting a cut in the middle of a workpiece without a pre-drilled entry point, expanding the range of tasks these blades can handle.
- 5-piece pack quantity - ensures you have replacement blades on hand for extended projects, reducing downtime when working through dense hardwood or thick sheet goods.
Why This Product
- Designed specifically for very fast, coarse straight cuts in hardwood and softwood from 7/32" to 2 3/8" thick - ideal when cut speed matters more than surface finish, such as rough framing, demolition carpentry, or construction lumber work.
- The T-Shank fits all major jig saw brands, so these blades integrate immediately into an existing tool setup without purchasing adapters or specialty tooling.
- Plunge cutting capability means the blades handle interior cutouts in plywood and OSB - tasks like installing electrical boxes, HVAC openings, or countertop cutouts - without needing a separate tool or pre-drilled pilot holes.
- Sold as a 5-piece set, giving you multiple blades for back-to-back cuts or extended project runs, which is especially useful when working through dense hardwood that accelerates blade wear.

Frequently Asked Questions
What jig saw shank type do these blades use, and will they fit my saw?
These blades use a T-Shank (universal T-Shank) design, which fits all major jig saw models - both corded and cordless - without requiring an adapter. If your jig saw accepts T-Shank blades, these will be a direct fit.
What is the maximum material thickness these blades can cut?
These blades are rated for materials from 7/32" up to 2 3/8" thick (approximately 5mm to 60mm), covering a wide range of lumber, plywood, and OSB thicknesses commonly encountered in construction and woodworking.
Are these blades suitable for fine finish cuts?
No - with 6 TPI and a coarse tooth configuration, these blades are optimized for very fast, straight cuts with a coarse finish. They are best suited for applications where cutting speed is the priority over surface smoothness, such as rough carpentry, structural lumber, and sheet goods like plywood and OSB.
Can these blades be used for plunge cutting?
Yes. The CMT JT144D blades support plunge cutting, allowing you to start a cut in the interior of a workpiece without a pre-drilled hole. This makes them useful for cutouts in plywood panels, OSB decking, and similar applications.
