Product Description
CMT 690.076 Profile Knives for Insert Shaper System are a pair of alloyed steel shaper knives sized 1-37/64 in. x 5/32 in. (40x4mm), engineered for use with CMT universal cutter heads. Designed for woodworkers who demand consistent, repeatable profiles on hardwood, softwood, MDF, and chipboard, these knives deliver long-lasting performance as part of the CMT Insert Shaper System. Whether you are shaping cabinet door profiles, running molding passes on a spindle moulder, or edge-profiling solid wood frames, the 690.076 knife pair provides the precision and durability to support production and fine woodworking alike.
Key Features
- Alloyed steel construction - provides long-lasting performance and resistance to wear during extended shaping operations on a variety of wood-based materials.
- 1-37/64 in. cutting height with 5/32 in. maximum thickness (40x4mm) - delivers a precise profile depth that matches the specifications of the CMT Insert Shaper System for accurate, repeatable results on every pass.
- Sold as a matched pair (2 knives) - both knives are dimensionally matched so the cutter head remains balanced, reducing vibration and producing a smoother surface finish.
- Compatible with CMT universal cutter heads - fits the range of CMT cutter heads designed for insert-style profile knives, allowing quick knife changes and the flexibility to run a variety of profiles on the same machine.
- Profile number 076 - a specific molding profile within the CMT Insert Shaper System, enabling consistent profile reproduction across production runs without the need for custom-ground tooling.
Why This Product
- The insert shaper system design means you can swap profiles quickly between jobs without replacing an entire cutter head - reducing downtime and tooling costs compared to single-profile solid heads.
- Alloyed steel material is matched to the demands of profiling hardwood, softwood, MDF, and chipboard, making this knife pair a practical choice for shops working across a range of panel and solid wood products.
- Because the knives are sold in a matched pair, the cutter head receives balanced cutting forces on both sides, helping maintain a smooth, consistent profile finish from the first pass to the last.
- Profile 076 is a defined, repeatable profile within the CMT system, making it straightforward to source replacement knives when the set eventually wears, rather than relying on custom tooling orders.
