Product Description
CMT 690.541 Profile Knives for Insert Shaper System - 1-31/32" x 5/32" (50x4mm), 2-Pack are precision-engineered shaper knives designed for use with CMT universal cutter heads, delivering consistent molding profiles across a wide range of woodworking applications. Sold as a matched pair, these alloyed steel profile knives slot directly into the CMT insert shaper system to produce repeatable, smooth profiles on hardwood, softwood, MDF, and chipboard - making them a reliable choice for cabinet door making, frame and panel work, and edge profiling on spindle moulders and profile machines alike.
Key Features
- Alloyed Steel Construction - made of alloyed steel for long-lasting performance, resisting wear during extended production runs on dense or abrasive materials.
- 50x4mm Knife Size (1-31/32" x 5/32") - precise dimensional format ensures a secure, repeatable fit in compatible insert cutter heads, reducing setup time and profile inconsistency.
- Profile Number 541 - Radius Range 8mm-16mm - delivers a specific, defined curve geometry suited to molding, edge profiling, and decorative shaping tasks where a consistent radius is critical to the finished result.
- Sold as a Matched Pair (2 knives) - both knives are manufactured and ground to the same profile, so they balance correctly in the cutter head and produce a uniform cut without vibration or chatter.
- Compatible with CMT Universal Cutter Heads (692 Series) - designed specifically for the CMT insert shaper system, allowing woodworkers to swap profiles quickly without changing the entire cutter head assembly.
- Wide Profile Knife Variety Available - part of a broad family of profile knives for the universal cutter head system, giving shops the flexibility to expand their molding capabilities over time using the same cutter body investment.
Why This Product
- Efficient Profile Changeovers - because these knives mount into a universal cutter head rather than requiring a dedicated head per profile, shops can switch between molding patterns quickly, reducing downtime between setups.
- Consistent Radius Output Across the 8mm-16mm Range - the defined radius geometry of profile 541 means every workpiece comes off the moulder or spindle shaper with the same curve, critical for matched sets of cabinet doors or frame components.
- Long-Lasting Alloyed Steel - the SP alloyed steel material resists edge degradation, so these knives stay sharp longer through production runs on hardwood and abrasive sheet goods like MDF and chipboard, lowering the cost per cut over time.
- Broad Machine Compatibility - sized at 50x4mm to work with spindle moulders, moulders, and profile and edging machines, these knives fit into existing shop equipment without requiring dedicated or specialized tooling.

Frequently Asked Questions
What cutter heads are these profile knives compatible with?
These knives are designed for use with the CMT Insert Shaper System, specifically the CMT 692 series universal cutter heads. They are also compatible with other insert shaper systems that accept 50x4mm profile knives.
What is the radius range produced by profile 541?
Profile 541 produces a radius in the range of 8mm to 16mm, making it suitable for curved molding and edge profiling work where a consistent arc geometry is required.
How many knives come in this package?
This listing includes 2 knives - a matched pair. Both knives carry the same profile 541 geometry and are intended to be installed together in the cutter head to ensure balanced cutting and a uniform profile.
What materials can these profile knives cut?
These alloyed steel profile knives are suitable for use on hardwood, softwood, MDF, and chipboard, covering the range of materials commonly used in cabinetry, furniture, and millwork production.
