Product Description
CMT Profile Knives for Insert Shaper System - 1-37/64" x 5/32" (40x4mm), 2-Pack are precision-engineered shaper knives designed for use with CMT universal cutter heads. Made from alloyed steel (SP material grade), these 40x4mm insert knives deliver long-lasting performance in molding, profiling, and edge-shaping operations on wood and wood-composite materials. Sold as a matched pair, they integrate seamlessly into the CMT Insert Shaper System to produce consistent, repeatable profiles on hardwood, softwood, MDF, and chipboard.
Key Features
- Alloyed Steel (SP) Construction - provides the material toughness needed for extended cutting life on both hardwood and engineered wood products, reducing how often knives need to be replaced.
- 1-37/64" Cutting Height - delivers a substantial profile reach, making these knives well suited for full-featured molding profiles and decorative edge work on cabinet doors and frames.
- 15mm Radius - the precisely ground 15mm radius produces smooth, consistent curved profiles in a single pass, minimizing sanding and secondary finishing work.
- 5/32" Maximum Thickness - the compact knife thickness ensures a secure, snug fit within 40x4mm insert shaper cutter head slots, keeping knives stable during high-speed operation.
- Pair of 2 Knives (KSS 40x4mm) - supplied as a matched pair so both sides of a symmetrical cut are covered simultaneously, saving setup time and ensuring balanced cutting performance.
- Compatible with Universal Cutter Heads - works with the full range of CMT 692 series insert shaper heads and other cutter heads accepting 40mm knives, offering broad machine compatibility across spindle moulders and profile machines.
- Long-Lasting Performance - engineered for sustained use in production and shop environments, reducing downtime and tooling costs over time.
Why This Product
- Woodworkers who need a purpose-built profile knife for the CMT Insert Shaper System get a ready-to-use matched pair (profile 177) in the correct 40x4mm size - eliminating the guesswork of sizing and fitment compatibility.
- The alloyed steel SP construction holds an edge through demanding runs on hardwood, softwood, MDF, and chipboard, making these knives a practical choice for both production shops and custom woodworking operations where consistent results matter.
- A 15mm radius and 1-37/64" cutting height combine to handle detailed molding and edge profiling tasks - from cabinet door making to frame and panel work - in a single tool, reducing the number of separate cutters needed in a shop inventory.
- The 40x4mm format is compatible with a variety of universal cutter heads, so these knives can work across multiple machines accepting that knife size, providing flexibility as a shop's equipment lineup changes or grows.
