Product Description
CMT Profile Knives for Insert Shaper System - 1-37/64 in. x 5/32 in. (40x4mm), 2-Pack are precision-crafted shaper knives designed for use with CMT universal cutter heads, giving woodworkers the flexibility to produce consistent molding profiles on hardwood, softwood, MDF, and chipboard. Made from alloyed steel (SP grade), these 40x4mm profile knives are sold as a pair and are engineered for long-lasting performance in demanding shaping and profiling applications including cabinet door making, frame and panel work, and edge profiling.
Key Features
- Alloyed Steel (SP) Construction - provides durability and resistance to wear, extending the working life of each knife even through repeated use on dense materials like hardwood and MDF.
- 1-37/64 in. Cutting Height - delivers a generous profile sweep, making these knives suitable for producing full molding profiles in a single pass and reducing the need for secondary operations.
- 5/32 in. (4mm) Knife Thickness - precisely machined to fit securely within compatible insert shaper cutter heads, ensuring stable seating and vibration-free cuts.
- 40x4mm Insert System Format - compatible with CMT universal cutter heads (692 series) and other insert shaper systems accepting this knife size, giving buyers broad machine compatibility across spindle moulders and profile machines.
- Sold as a Matched Pair - both knives in the pack are ground to the same profile for balanced cutting, reducing machine vibration and producing smoother surface finishes.
- Variety of Profile Knives Available - part of a broader family of insert shaper profiles, allowing woodworkers to build a versatile knife library for a wide range of molding and cabinetry applications.
Why This Product
- For shops running a CMT 692 series cutter head or any compatible insert shaper system, these 40x4mm knives swap in quickly and lock securely, minimizing downtime between profile changes on the spindle moulder.
- The alloyed steel construction holds an edge through extended production runs on hardwood, softwood, MDF, and chipboard - reducing the frequency of knife changes and keeping operations running smoothly.
- Purchasing knives as a matched pair ensures balanced cutter head loading, which translates directly to cleaner, smoother surface finishes and less sanding time after profiling.
- As part of CMT's broad insert shaper knife system, these 40x4mm knives can be mixed and matched with other available profiles, giving woodworkers a cost-effective way to expand their molding and cabinetry capabilities without investing in additional cutter heads.
