Product Description
CMT Profile Knives for Insert Shaper System - 1-37/64 in. x 5/32 in. (40x4mm), Profile 020, 2-Pack are precision-made alloyed steel shaper knives designed to work with CMT universal cutter heads, giving woodworkers a reliable and consistent solution for molding, profiling, and edge-shaping tasks. Sold as a matched pair, these 40x4mm insert knives are built for long-lasting performance in demanding shop environments, making them a practical choice for cabinetmakers, furniture builders, and millwork professionals who depend on repeatable results.
Key Features
- Pair of KSS 40x4mm Profile Knives - sold as a matched set of 2, so both knives are replaced together for balanced cutting and consistent profile output every time.
- Made of alloyed steel - provides the hardness and edge retention needed to maintain a sharp, clean profile through extended production runs on wood and wood-composite materials.
- Compatible with universal cutter heads - fits the CMT insert shaper system and other cutter heads accepting 40mm knives, giving you flexibility across multiple machines without buying separate tooling for each setup.
- Long-lasting performance - engineered to minimize downtime and tool changeovers, keeping your shaper or moulder running productively for longer between knife replacements.
- Cutting height of 1-37/64 in. (40mm) - provides the profile depth needed for full molding passes, reducing the need for multiple shallow cuts and speeding up workflow.
- Maximum thickness of 5/32 in. (4mm) - a slim knife body that seats securely in the cutter head slot, ensuring stable clamping and vibration-free cutting for smooth surface finishes.
Why This Product
- If you already run CMT universal cutter heads or any insert shaper system accepting 40mm knives, profile 020 drops right in without adapters or special tooling - you get a fast, straightforward setup that keeps production moving.
- Alloyed steel construction means these knives hold their edge through repeated use on hardwood, softwood, MDF, and chipboard, reducing how often you need to stop and swap tooling mid-job.
- Buying a matched pair ensures both cutting edges wear evenly and produce an identical profile, which matters when you are running cabinet doors, frames, or molding that needs to match piece to piece.
- The 40x4mm form factor is part of a broader system of interchangeable CMT profile knives, so once your cutter head is in place, switching to a different profile requires only a knife swap - not an entirely new cutter setup.

Frequently Asked Questions
What cutter heads are these profile knives compatible with?
These 40x4mm profile knives are designed for use with CMT universal cutter heads and other insert shaper systems that accept 40mm knives. They are part of the CMT Insert Shaper System and are intended to pair with compatible cutter heads from that system.
How many knives come in a package?
Each order includes a matched pair of 2 profile knives (KSS 40x4mm). Both knives should be installed together to ensure balanced cutting and a consistent profile on your workpiece.
What materials can these knives cut?
These alloyed steel profile knives are suitable for use on hardwood, softwood, MDF, and chipboard - making them well-suited for cabinetry, millwork, furniture production, and general woodshop profiling work.
What do the dimensions 1-37/64 in. x 5/32 in. refer to?
The 1-37/64 in. (40mm) dimension is the cutting height, which determines how deep a profile pass the knife can make. The 5/32 in. (4mm) dimension is the maximum knife thickness, which corresponds to the slot width in the compatible cutter head bodies. Together, these dimensions define which cutter heads and shaper systems the knife will fit correctly.
