Product Description
CMT 690.015 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), designed for use with CMT universal cutter heads in the insert shaper system. These KSS-format knives deliver long-lasting performance across a wide range of profiling and molding operations, making them a reliable choice for woodworkers who demand consistent, repeatable results in cabinet making, edge profiling, and frame and panel work. The 40x4mm format is compatible with a variety of universal insert cutter heads, giving craftsmen the flexibility to run different profiles without changing the entire tooling setup.
Key Features
- Alloyed Steel Construction - material designation SP (special alloyed steel) provides durability and edge retention through repeated cuts in hardwood, softwood, MDF, and chipboard, reducing the need for frequent replacement.
- 1-37/64 in. Cutting Height - a generous cutting height allows the knife to produce deep, full profiles in a single pass, improving efficiency and surface consistency on molding and profiling tasks.
- 5/32 in. (4mm) Maximum Thickness - the precise knife thickness matches the 40x4mm KSS insert slot specification, ensuring a secure, accurate fit in compatible universal cutter heads and eliminating chatter or movement during operation.
- Sold as a Matched Pair - two knives are included per package, allowing balanced loading of the cutter head for safer operation and smoother surface finish on profiled workpieces.
- Variety of Profiles Available - profile number 015 is part of a broad range of insert shaper knife profiles designed for the same universal system, so expanding a shop's profiling capability is straightforward without investing in entirely new tooling.
- Long-Lasting Performance - engineered for extended service life, these shaper knives maintain profile accuracy over time, lowering cost-per-cut across high-volume production or frequent use in custom woodworking.
Why This Product
- The 40x4mm KSS format is compatible with a variety of universal insert cutter heads, meaning a single set of cutter heads can accept many different profile knives - profile 015 included - making tooling investments go further.
- Alloyed steel construction (SP material) supports long-lasting edge retention, so production runs on hardwood, softwood, MDF, and chipboard stay consistent without constant re-sharpening or knife swaps.
- Selling as a matched pair of 2 knives ensures the cutter head is properly balanced from the start, reducing vibration and contributing to a cleaner, smoother profile on the finished workpiece.
- Profile number 015 is part of a large library of compatible insert shaper profiles, giving woodworkers and millwork shops the ability to expand their molding and edge profiling capabilities without replacing the entire cutter head assembly.

Frequently Asked Questions
What cutter head system are these profile knives designed for?
The CMT 690.015 knives are designed for the CMT Insert Shaper System and are compatible with universal cutter heads that accept 40x4mm (KSS format) insert knives. They are sold as part of a variety of profile knives intended for use with universal cutter heads in that system.
How many knives are included in one package of the 690.015?
Each package contains 2 knives - a matched pair. Using a matched pair ensures proper balance in the cutter head during operation, which contributes to smoother cutting and a more consistent profile on the workpiece.
What materials can these shaper knives be used on?
The 690.015 profile knives are suited for use on hardwood, softwood, MDF, and chipboard. Their alloyed steel (SP) construction is intended to provide long-lasting performance across these common woodworking and millwork materials.
What does the knife size 1-37/64 in. x 5/32 in. (40x4mm) refer to?
The 1-37/64 in. dimension is the cutting height of the knife, which determines the maximum depth of profile the knife can produce. The 5/32 in. (4mm) dimension is the maximum thickness of the knife body, which must match the insert slot specification of the cutter head - in this case the 40x4mm KSS standard.
