Product Description
CMT 690.034 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), designed for use with CMT universal cutter heads in the insert shaper system. These KSS-style profile knives deliver long-lasting performance when molding, profiling edges, and shaping cabinet components on spindle moulders and profile machines. Sold as a pair of 2 knives, the 690.034 set is built for woodworkers and millwork shops that demand consistent, repeatable profiles across hardwood, softwood, MDF, and chipboard.
Key Features
- Pair of profile knives (KSS 40x4mm) - two matched knives per set means balanced cutting and no need to source individual blades separately, reducing setup time at the cutter head.
- 1-37/64 in. cutting height - a generous cutting height allows the knife to engage deeper profiles in a single pass, supporting efficient molding and reduced multi-pass operations.
- 5/32 in. maximum thickness - the precise knife thickness ensures a secure, consistent seat in compatible 40mm insert cutter head slots, minimizing vibration during profiling runs.
- Made of alloyed steel (SP material) - alloyed steel construction provides the toughness needed to hold a sharp edge through extended production runs on hardwood and engineered wood materials.
- Compatible with universal cutter heads - designed to fit a variety of insert shaper cutter heads, giving shops flexibility to use one knife system across multiple machines and head configurations.
- Long-lasting performance - durable material and precision knife geometry translate directly to fewer blade changes, lower tooling costs, and more consistent profile output over time.
Why This Product
- For shops running spindle moulders or profile and edging machines, the 40x4mm knife format fits a wide range of universal insert cutter heads - meaning this pair integrates into an existing tooling setup without requiring a dedicated proprietary head.
- The alloyed steel construction holds up across hardwood, softwood, MDF, and chipboard, making these knives a practical choice for cabinet door making, frame and panel work, and edge profiling without frequent tool changes.
- Sold as a matched pair of 2, the 690.034 set ensures both knives in a balanced cutter head are replaced or installed together, maintaining proper balance and profile consistency critical to smooth surface finishes.
- Profile number 034 is part of a variety of profile knives available for the insert shaper system, so woodworking shops can build a library of profiles around a single compatible cutter head platform.
