Product Description
CMT 690.058 Profile Knives for Insert Shaper System are precision-ground, alloyed steel cutting knives designed to work with CMT universal cutter heads, giving woodworkers a reliable solution for molding, profiling, and edge-shaping tasks. Sold as a pair, these 40x4mm knives (1-37/64 in. cutting height x 5/32 in. maximum thickness) slot into the CMT insert shaper system to deliver consistent, repeatable profiles in hardwood, softwood, MDF, and chipboard applications.
Key Features
- Alloyed steel construction - provides long-lasting performance and durability through extended production runs, reducing the need for frequent knife replacement.
- Pair of KSS 40x4mm profile knives - sold in a matched set so both knives maintain symmetrical, balanced cuts for smooth, accurate profiling on every pass.
- 1-37/64 in. cutting height x 5/32 in. maximum thickness - the specific knife geometry delivers a defined profile shape, ensuring dimensional accuracy across repeated cuts without adjustment.
- Compatible with CMT universal cutter heads - part of a comprehensive insert shaper system, these knives work with a variety of CMT cutter heads for versatile molding and profiling applications.
- Wide material compatibility - cuts cleanly through hardwood, softwood, MDF, and chipboard, making these knives well-suited for cabinet door making, frame and panel work, and edge profiling.
Why This Product
- For woodworkers who need interchangeable profile options without investing in a new cutter head for every molding pattern, this insert knife system allows quick, cost-effective profile changes using the same universal cutter head body.
- The alloyed steel construction ensures these shaper knives maintain their edge through demanding production work, keeping downtime low and surface finish quality high on both solid wood and engineered sheet goods.
- The matched pair format eliminates imbalance concerns - both knives are ground to the same profile specification, which is essential for achieving a smooth finish and safe operation on a spindle moulder or moulder machine.
- With a cutting height of 1-37/64 in., profile number 058 is engineered to produce a specific decorative or functional profile, giving cabinet makers and millwork shops a repeatable result that fits within the broader CMT insert shaper system lineup.
