Product Description
CMT 690.082 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), engineered for use with CMT universal cutter heads and compatible insert shaper systems. Designed for woodworkers who demand consistent, repeatable molding profiles, these knives deliver long-lasting performance on a wide range of wood-based materials - from solid hardwood and softwood to engineered sheet goods. Whether you are producing cabinet door profiles, decorative moldings, or edge details, the 690.082 knife set brings precision and reliability to spindle moulder and shaper operations.
Key Features
- Alloyed steel construction - provides durability and edge retention through extended production runs, reducing the frequency of knife changes and downtime.
- 40x4mm knife size (1-37/64 in. x 5/32 in.) - the standardized KSS 40x4mm format ensures a secure, repeatable fit in compatible universal cutter heads, delivering consistent profile geometry cut after cut.
- Sold as a matched pair - both knives are balanced and matched to work together in the cutter head, promoting smooth, vibration-free cutting for cleaner surface finishes.
- Compatible with the CMT Insert Shaper System and universal cutter heads - a variety of profile knives are available in this system, allowing you to build a versatile library of profiles without investing in multiple dedicated cutter heads.
- Long-lasting performance - the alloyed steel material is selected specifically for shaper knife applications, meaning you get more linear feet of profiling before resharpening is needed.
Why This Product
- Versatile profile library in one system - because the CMT Insert Shaper System supports a variety of profile knives in the KSS 40x4mm format, the 690.082 knives let you expand your profiling capabilities without purchasing entirely new tooling for each new shape.
- Matched pair for balanced cutting - receiving two knives together means you can immediately load a properly balanced pair into your cutter head, avoiding the imbalance and vibration that can affect cut quality and machine wear.
- Alloyed steel for production durability - for woodworkers running medium to high production volumes in hardwood, softwood, MDF, or chipboard, the alloyed steel composition supports sustained cutting performance without frequent interruptions for sharpening.
- Standardized 40x4mm footprint - the KSS 40x4mm format is widely compatible with universal insert shaper cutter heads, making these knives a practical, flexible choice for shops already invested in insert-style shaper tooling.

Frequently Asked Questions
What cutter heads are these profile knives designed for?
The 690.082 knives are designed for use with CMT universal cutter heads that accept KSS 40x4mm format knives, which is the standard sizing for the CMT Insert Shaper System. Always confirm your cutter head accepts 40x4mm knives before mounting.
How many knives come in each pack?
Each pack includes 2 profile knives - sold as a matched pair. Both knives are intended to be loaded together into the cutter head to maintain proper balance during operation.
What materials can these knives be used on?
These alloyed steel profile knives are suited for use on hardwood, softwood, MDF, and chipboard, making them a practical choice for both solid wood and engineered wood panel applications in cabinetry and millwork production.
What is the knife size and what do the dimensions mean?
The knives measure 1-37/64 in. in cutting height and 5/32 in. in maximum thickness, corresponding to the metric 40x4mm KSS standard. The cutting height refers to how deep a profile the knife can produce, while the thickness determines compatibility with the insert slot in your cutter head.
