CMT 690.545 Profile Knives for Insert Shaper System are precision-ground, alloyed steel shaping knives engineered for use with CMT universal cutter heads. Sold as a pair, these 50x4mm (1-31/32 in. x 5/32 in.) knives are designed to deliver long-lasting, consistent molding profiles on a wide range of wood-based materials. Whether you are running a spindle moulder, moulder, or profile and edging machine, these insert-style profile knives slot into the CMT 692 series cutter head system to produce smooth, repeatable results across production and custom woodworking applications.

Key Features

• Alloyed Steel Construction - made of alloyed steel for durability under repeated use, reducing the frequency of replacement and maintaining profile accuracy over time.
• Cutting Height of 1-31/32 in. - provides ample depth of cut for molding and profiling work including cabinet door making, frame and panel construction, and edge profiling.
• Maximum Thickness of 5/32 in. (4mm) - a precise knife thickness engineered to seat securely within compatible insert shaper cutter heads, ensuring stable, chatter-free cutting.
• 35mm Radius - the built-in radius profile of 35mm allows the knives to produce a specific curved molding shape, making them suited for decorative edge work and architectural millwork.
• Universal Cutter Head Compatibility - designed to work with the CMT insert shaper system, compatible with a variety of profile knives and universal cutter heads so you can expand your profile library without purchasing new heads.
• Sold as a Pair (2 knives) - both knives are included in a single pack, so you have a matched, balanced set ready to install and run without sourcing individual pieces separately.
• Long-Lasting Performance - the material and construction are optimized for extended service life, lowering the cost-per-profile cut across high-volume woodworking operations.

Why This Product

• For woodworkers and cabinet shops that already use the CMT universal cutter head system, these 50x4mm insert knives allow easy profile changes without swapping entire tooling assemblies - saving setup time and tooling cost.
• The 35mm radius profile built into the 690.545 knives delivers a specific decorative shape, making them a targeted solution for molding, frame and panel work, and cabinet door edge profiles rather than a general-purpose option.
• Alloyed steel construction is engineered for long-lasting performance, meaning fewer interruptions for replacement or sharpening during demanding production runs on hardwood, softwood, MDF, and chipboard.
• Buying knives in a matched pair ensures balanced cutting forces in the cutter head, which contributes to smoother surface finishes and more consistent profile results across every workpiece.
