CMT 690.546 Profile Knives for Insert Shaper System are a matched pair of alloyed steel shaper knives sized 1-31/32 in. x 5/32 in. (50x4mm), engineered for use with CMT universal cutter heads in the insert shaper system. Designed for woodworkers who demand consistent molding profiles across hardwood, softwood, MDF, and chipboard, these knives deliver long-lasting performance in spindle moulders, moulders, and profile and edging machines. Whether you are producing cabinet door frames, decorative moldings, or precision edge profiles, the 690.546 profile knives provide a reliable and repeatable cut in demanding production and shop environments.

Key Features

• Alloyed Steel Construction - the SP alloyed steel material resists wear and maintains a sharp cutting edge longer, reducing downtime and regrinding frequency in high-volume shaping operations.
• Sold as a Matched Pair (2 knives) - both knives in the pair are ground and matched together, ensuring balanced performance in the cutter head and a consistent, vibration-free cut every time.
• 1-31/32 in. Cutting Height - the generous 1-31/32 in. cutting height allows this pair to shape substantial profiles in a single pass, improving efficiency when working on larger molding and frame profiles.
• 5/32 in. Maximum Thickness - the 5/32 in. knife thickness is precisely sized to seat securely in compatible insert shaper cutter heads, maintaining tight tolerances for accurate, repeatable profile reproduction.
• 25mm Radius - the 25mm radius profile is suited for producing smooth, flowing curves in molding, edge profiling, and decorative frame work without requiring multiple passes or additional tooling.
• Designed for Universal Cutter Heads - compatible with the CMT 692 series and other universal insert shaper systems accepting 50x4mm knives, giving woodworkers the flexibility to use these knives across a range of machines.
• Long-Lasting Performance - engineered for durability in shaping hardwood, softwood, MDF, and chipboard, these knives maintain profile fidelity over extended use, making them cost-effective for both production shops and craftsmen.

Why This Product

• The 50x4mm knife size and universal compatibility with CMT 692 series cutter heads means you can expand your profile library without investing in new tooling systems - these knives slot into equipment you likely already own.
• The 25mm radius and 1-31/32 in. cutting height make the 690.546 pair well suited for cabinet door making, frame and panel work, and decorative molding profiles where a consistent, smooth curve is critical to the finished result.
• Alloyed steel construction and precision pairing of both knives support long service life and balanced cutter head operation, which matters in production settings where unplanned tool changes are costly.
• The variety of profile knives available in the CMT insert shaper system means you can build a comprehensive set of shaping profiles over time, using this same system and the same cutter heads across many different molding applications.
