Product Description
CMT 690.054 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 in the insert shaper system. Designed for woodworkers and cabinet makers who demand consistent, repeatable profiles, these knives bring long-lasting performance to molding, edge profiling, and frame-and-panel work on hardwood, softwood, MDF, and chipboard. Sold as a set of 2 knives, the 690.054 pair offers a specific profile geometry suited to professional shaper operations where precision and repeatability are essential.
Key Features
- Alloyed Steel Construction - delivers long-lasting performance and resistance to dulling during repetitive production runs on dense or abrasive workpieces.
- 40x4mm Knife Size (1-37/64 in. x 5/32 in.) - fits a wide range of universal cutter heads designed for this insert shaper system, making it easy to integrate into your existing setup without additional tooling changes.
- Part of a Variety of Profile Knives for Universal Cutter Heads - allows you to swap profiles on the same cutter head body, expanding your shaping capabilities without purchasing entirely new tooling for each profile.
- Sold as a Matched Pair (KSS 40x4mm) - both knives are matched to the same profile and tolerances, ensuring balanced cuts and a smooth, consistent surface finish on every pass.
Why This Product
- The 40x4mm insert knife format works with CMT universal cutter heads, giving you the flexibility to run multiple profiles from a single cutter head body - reducing tooling costs and changeover time at the shaper.
- Alloyed steel construction means the cutting edges maintain their geometry over extended use, reducing the frequency of knife replacements during high-volume molding and profiling tasks.
- Purchasing in a matched pair ensures both knives in the cutter head are performing identically, which is critical for balanced cutting, reduced vibration, and a quality surface finish on hardwood, softwood, MDF, and chipboard.
- Profile number 054 is a specific geometry within the CMT insert shaper knife range, making it straightforward to identify and reorder the exact profile you need for cabinet door making, frame-and-panel assemblies, and edge profiling work.
