Product Description
CMT JT244DDC-5 Jig Saw Blades - Wood/Coarse Curve Duo Cut (HCS) 4" x 6TPI, 5-Piece Pack by CMT delivers fast, aggressive curve cutting through softwood, hardwood, plywood, and OSB. The special "Duo" double-tooth geometry produces rapid curved and plunge cuts in wood stock ranging from 7/32" to 2-3/8" thick, making this 5-pack a go-to choice for carpenters, woodworkers, and contractors who demand consistent performance in coarse freehand and guided curve work.
Key Features
- Special "Duo" Double-Tooth Design: The 4mm tooth distance Duo configuration enables faster curve cuts than standard single-tooth geometry - reducing time spent on each pass through softwood, hardwood, plywood, and OSB.
- High-Carbon Steel (HCS) Construction: Heat-treated HCS material provides the flexibility and toughness needed for aggressive curved cuts in wood - resisting blade flex and breakage during demanding freehand applications.
- Universal T-Shank: The T-shank fits all major jig saws without an adapter - compatible with cordless and corded tools from virtually every major brand, reducing setup time and tool inventory.
- 6 TPI Coarse Tooth Pitch: At 6 teeth per inch, the coarse tooth spacing removes material quickly for fast, rough curve cuts - ideal when cut speed matters more than surface finish.
- Plunge Cutting Capability: Engineered for plunge cuts as well as through-cuts - letting you start a cut in the middle of a panel without a pre-drilled hole, expanding layout flexibility.
- Wide Material Thickness Range: Cuts wood from 7/32" up to 2-3/8" thick - covering thin sheet goods like plywood and OSB all the way through substantial dimensional lumber in a single blade profile.
- 5-Piece Pack Quantity: Supplied as a 5-piece set - giving you multiple blades on hand to swap in during extended projects or when tackling abrasive sheet materials that accelerate wear.
Why This Product
- The Duo double-tooth geometry is purpose-built for coarse curve cutting in wood - if you regularly rough-cut arcs, circles, or freeform shapes in hardwood or plywood, this blade geometry cuts faster than conventional single-tooth profiles of the same TPI rating.
- With a cutting height of 3" and a maximum material thickness of 2-3/8", this blade handles the full range of common wood panel and dimensional lumber thicknesses encountered in framing, cabinetry, and carpentry work without switching to a longer blade.
- Plunge cutting support makes this blade especially practical for rough-in and remodel work where you need to open up panels or create interior cutouts in plywood or OSB without drilling a starter hole first.
- Buying in a 5-piece pack means you have replacement blades ready when one dulls mid-job - particularly valuable when working through abrasive materials like OSB where cutting edges wear faster than on clear softwood.

Frequently Asked Questions
What does the "Duo" or "Duo Cut" designation mean on these blades?
The "Duo" designation refers to the special double-tooth configuration with a 4mm tooth distance. This geometry is designed to make faster curve cuts compared to a conventional single-tooth layout at the same TPI rating. It is specifically optimized for fast, coarse curved cutting in softwood, hardwood, plywood, and OSB.
What material thickness range can these blades handle?
These blades are rated for wood material from 7/32" up to 2-3/8" thick. This covers thin sheet goods such as plywood and OSB on the lower end, and thicker dimensional hardwood and softwood toward the upper limit. The 3" cutting height supports this full range.
Are these blades compatible with my jig saw?
Yes - these blades use a universal T-shank, which fits all major corded and cordless jig saws that accept the standard T-shank interface. No adapter is required for T-shank compatible tools.
Can these blades make plunge cuts, or are they only for through-cuts?
These blades support plunge cutting. This means you can start a cut in the interior of a panel - such as an OSB or plywood sheet - without needing to pre-drill a starter hole, which makes them well-suited for interior cutouts and rough-in work.
