Product Description
CMT 690.089 Profile Knives for Insert Shaper System are a matched pair of alloyed steel shaper knives sized 1-37/64 in. x 5/32 in. (40x4mm), designed to work with CMT universal cutter heads in the insert shaper system. These knives bring a specific molding profile to woodworking operations such as cabinet door making, edge profiling, and frame and panel work - delivering long-lasting, repeatable results on hardwood, softwood, MDF, and chipboard. Whether you are running a spindle moulder, a moulder, or a profile and edging machine, these 40x4mm knives integrate smoothly into the CMT 692 series cutter head platform and other compatible insert shaper systems accepting 40mm or 50mm knives.
Key Features
- Alloyed steel construction - provides the toughness and durability needed for sustained production runs across hardwood, softwood, MDF, and chipboard without premature wear.
- Matched pair (2 knives per pack) - both knives are balanced and paired together so the cutter head stays dynamically balanced during high-speed profiling operations.
- 40x4mm knife format (1-37/64 in. x 5/32 in.) - a widely used insert knife size that fits CMT 692 series cutter heads and other universal insert shaper systems, reducing the need for additional tooling investments.
- Long-lasting performance - engineered to maintain profile accuracy over extended use, meaning fewer tool changes and more consistent surface finishes across a production run.
- Part of the CMT universal cutter head system - one cutter head body accepts a wide variety of profile knives, so switching between profiles is fast and cost-effective rather than requiring separate dedicated heads.
- Profile number 089 - a specific, identifiable profile designation that makes reordering and matching profiles across jobs straightforward and error-free.
Why This Product
- If you already own a CMT 692 series cutter head or a compatible universal insert shaper head, these 40x4mm knives let you expand your profile library without purchasing additional tooling bodies - just swap the knives and run a different profile.
- The alloyed steel material and long-lasting performance design mean these knives hold their edge through demanding production work on hardwood and engineered panels like MDF and chipboard, reducing downtime from frequent resharpening or replacement.
- Sold as a matched pair, these knives are ready to install directly into the cutter head as a balanced set - no extra sourcing or pairing required before getting back to work on molding, edge profiling, or cabinet door making.
- The 40x4mm format is compatible with both 40mm and 50mm insert shaper systems, making these knives a flexible choice for shops running more than one machine platform.
