Key Features
- Alloyed Steel Construction - provides the durability and edge retention needed for extended use in demanding shaping and molding operations, reducing the frequency of knife replacement and downtime.
- 40x4mm Knife Size (1-37/64 in. x 5/32 in.) - a standard insert shaper format that fits CMT 692 series cutter heads and other compatible universal cutter heads, giving you broad machine compatibility from a single knife pair.
- 8mm Radius Profile - a defined, repeatable curve geometry that produces smooth, consistent profile results on every pass, which is critical for matched door frames, cabinet moldings, and panel edges.
- Sold as a Matched Pair - both knives in the set are ground to the same profile, ensuring balanced cutting action in the cutter head and reducing vibration for a cleaner surface finish.
- Compatible with Universal Cutter Heads - works across a variety of CMT insert shaper cutter heads, so you can expand your profile library without investing in entirely new tooling systems.
- Long-Lasting Performance - engineered for consistent output over extended production runs, meaning less frequent tool changes and more time on productive work.
Why This Product
- The 8mm radius profile and precise 40x4mm dimensions make this knife pair well-suited for woodworkers who need repeatable, matched profiles for cabinet door making and decorative frame work - where consistency across multiple workpieces is essential.
- Alloyed steel construction holds up through high-volume shaping sessions on hardwood and softwood alike, making this pair a practical choice for shops that run spindle moulders or profile and edging machines regularly.
