CMT 690.077 Profile Knives for Insert Shaper System are a matched pair of alloyed steel shaping knives sized 1-37/64 in. x 5/32 in. (40x4mm), engineered for use with CMT universal cutter heads in the insert shaper system. Designed for woodworkers and shop professionals who demand consistent molding profiles on hardwood, softwood, MDF, and chipboard, these KSS-format profile knives deliver long-lasting performance in spindle moulding, cabinet door making, edge profiling, and frame-and-panel applications. Sold as a pair of 2 knives, the 690.077 set offers a precise profile geometry matched to CMT 692 series cutter heads and other insert shaper cutter heads accepting 40mm knives.

Key Features

• Alloyed steel construction - provides durability and edge retention over extended production runs, reducing the frequency of knife changes during demanding shaping tasks.
• 1-37/64 in. cutting height (40mm) - delivers ample profile depth for a wide range of molding and edge profiling work on furniture components, cabinet doors, and architectural trim.
• 5/32 in. (4mm) maximum thickness - ensures a precise, stable fit within compatible CMT insert shaper cutter heads for repeatable, chatter-free cuts.
• KSS 40x4mm format - matches the standardized insert shaper knife slot size, making these knives compatible with CMT universal cutter heads and other 40mm insert shaper systems for broad workshop versatility.
• Sold as a matched pair - both knives in the pair are ground to the same profile, so balanced cutting is maintained on the cutter head, resulting in smoother surface finish and reduced vibration.
• Profile variety available - part of a wide range of CMT profile knives for the universal cutter head system, allowing woodworkers to build a library of profiles for different molding, edging, and door-making applications.

Why This Product

• For shops running CMT 692 series cutter heads or other insert shaper systems accepting 40mm knives, the 690.077 provides a direct drop-in fit with no modification, saving setup time and keeping production moving.
• The alloyed steel material and precision-matched pair format mean both edges wear evenly, which helps maintain profile accuracy across large production batches of moldings, cabinet doors, and frames.
• Because these knives are part of a broad CMT profile knife range for the universal cutter head system, a single cutter head body can be shared across many profiles - replacing only the knives rather than buying separate tooling sets for each profile.
• With compatibility across hardwood, softwood, MDF, and chipboard, these insert shaper knives serve as a versatile solution for custom woodworking shops, millwork operations, and cabinet manufacturers working with multiple material types.
