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 woodworking professionals who demand clean, repeatable molding profiles. Made of alloyed steel for long-lasting durability, this pair of 40x4mm profile knives integrates with CMT universal cutter heads, making them a versatile addition to any spindle moulder, moulder, or profile and edging machine setup. Whether you are shaping cabinet door frames, creating decorative moldings, or profiling solid wood edges, these insert shaper knives deliver consistent results across hardwood, softwood, MDF, and chipboard.

Key Features

• Alloyed steel construction - provides long-lasting performance through extended production runs, reducing the frequency of knife changes and downtime on the shop floor.
• 1-37/64 in. cutting height with 5/32 in. maximum thickness (40x4mm) - precise knife dimensions ensure the profile registers correctly in compatible cutter heads for accurate, repeatable molding and profiling results every time.
• Designed for the CMT Universal Cutter Head (Insert Shaper System) - fits into the KSS 40x4mm knife slot system, giving woodworkers the flexibility to swap profiles quickly without replacing the entire cutter head assembly.
• Sold as a matched pair - both knives in the set are ground to the same profile specification, ensuring balanced cuts that reduce vibration and deliver a smoother surface finish.
• Wide profile knife selection available - part of a variety of profile knives offered for the universal cutter head system, so shops can build a library of profiles using the same compatible cutter heads.

Why This Product

• For woodworking shops that run a variety of molding profiles, the insert shaper system approach means investing once in cutter heads and then simply swapping 40x4mm knife pairs - reducing tooling costs and changeover time compared to dedicated single-profile heads.
• The alloyed steel material provides durability across demanding materials including hardwood, softwood, MDF, and chipboard, making these knives a practical choice for production environments where multiple material types are processed daily.
• The 40x4mm knife size is compatible with universal cutter heads in the KSS format, giving buyers the assurance that this investment in profile knives will work across a range of compatible machines rather than being locked to a single proprietary tool body.
• Purchasing knives in a matched pair (2 per pack) means both cutting edges are balanced by design - an important factor for smooth, chatter-free cuts on profile and edging machines, spindle moulders, and moulders alike.
