Key Features
- Alloyed Steel Construction - made of alloyed steel for durability and long-lasting performance, reducing the frequency of knife replacement during demanding production runs.
- 40x4mm Knife Size (1-37/64 in. x 5/32 in.) - precise dimensions ensure a secure, accurate fit in compatible cutter heads, producing clean and consistent profile cuts with minimal tear-out.
- Sold as a Matched Pair - both knives in the set are matched for balanced cutting performance, helping maintain smooth operation and reducing vibration in the cutter head.
- Designed for the CMT Universal Cutter Head System - purpose-built compatibility with CMT insert shaper cutter heads means no guesswork in fitment, giving users confidence that the knives will seat and perform as intended.
- Profile Number 066 - a specific molding profile in the CMT Insert Shaper System range, allowing woodworkers to select the exact shape needed for cabinet door making, frame and panel work, or decorative edge profiling.
- Wide Material Compatibility - suitable for hardwood, softwood, MDF, and chipboard, making these knives a versatile choice across cabinetry, furniture, and millwork applications.
Why This Product
- A complete insert shaper solution - the CMT Insert Shaper System approach means profile knives can be swapped in and out of a universal cutter head, reducing the cost of owning multiple dedicated shaper heads while expanding the range of profiles available in the shop.
- Consistent, repeatable profiles - with a fixed profile number (066) and matched pair design, these knives produce the same molding shape run after run, which is critical for cabinet door production and frame-and-panel joinery where uniformity matters.
- Built for longevity in production environments - the alloyed steel material is selected for long-lasting performance, meaning fewer interruptions to production and a lower cost per profile cut over the life of the knives.
- Broad machine compatibility - the 40x4mm knife size is a standard format accepted by spindle moulders, moulders, and profile and edging machines, giving these knives flexible utility across different shop setups.
