Product Description
CMT 690.062 Profile Knives for Insert Shaper System are a precision-ground 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, cabinet makers, and millwork professionals who demand consistent profiles and long-lasting cutting performance, these 40x4mm knives deliver repeatable results on a wide range of profiling and molding applications. Whether you are shaping hardwood cabinet door frames or running softwood molding profiles, this pair of SP-grade alloyed steel knives is built to perform through extended production runs.
Key Features
- Pair of profile knives (KSS 40x4mm): sold as a matched set of 2 knives - both knives are included so you can mount and balance the cutter head right away without sourcing a second knife separately.
- Alloyed steel (SP) construction: made of alloyed steel for superior edge retention and durability - meaning fewer interruptions for sharpening during demanding production runs.
- Cutting height of 1-37/64 in.: the generous cutting height allows for substantial profile depth in a single pass, supporting clean and accurate molding profiles without requiring multiple setups.
- Maximum thickness of 5/32 in. (4mm): the knife body is sized to 5/32 in. thick, which is the standard dimension for compatibility with universal insert cutter heads accepting 40mm knives.
- Universal cutter head compatibility: designed for the CMT universal cutter heads, giving shops the flexibility to run a variety of profile knives on a single cutter head system and reduce tooling inventory.
- Long-lasting performance: the alloyed steel material is selected for extended service life, which reduces downtime and replacement costs over time.
Why This Product
- Shops running a spindle moulder, moulder, or profile and edging machine can standardize on one cutter head system and swap profile knives quickly - the 40x4mm format fits universal cutter heads, so changing profiles takes minutes rather than requiring a full tooling changeout.
- Alloyed steel construction means these knives maintain a sharp cutting edge through hardwood, softwood, MDF, and chipboard without rapid dulling, making them a practical choice for mixed-material production environments.
- The CMT insert shaper system profile numbering (profile 062) makes it straightforward to identify and reorder the exact profile you need, reducing the risk of ordering the wrong knife for a repeat job.
- Buying a matched pair ensures both knife seats in the cutter head are loaded with identical cutting geometry, which is essential for balanced cutting, smooth surface finish, and safe tool operation.
