Product Description
CMT 690.096 Profile Knives for Insert Shaper System are a pair of alloyed steel shaper knives sized 1-37/64 in. x 5/32 in. (40x4mm), designed to work with CMT universal cutter heads for precision molding and profiling operations. These KSS-format insert knives deliver long-lasting performance on a wide range of wood-based materials, making them a practical choice for woodworkers and cabinet makers who rely on consistent, repeatable profiles in spindle moulder and shaper applications.
Key Features
- Alloyed steel construction - provides durability and edge retention for extended cutting sessions on hardwood, softwood, MDF, and chipboard without premature dulling.
- KSS 40x4mm knife format - sized at 1-37/64 in. x 5/32 in. to fit the CMT universal cutter head insert system, ensuring a secure, repeatable fit every time the knives are mounted or swapped.
- Part of a broad profile knife family - one of a variety of profile knives available for the universal cutter heads, giving woodworkers the flexibility to change profiles quickly without replacing the entire cutter head assembly.
- Sold in pairs - two matched knives are included per pack, so both cutter slots are covered for balanced cutting and smooth surface results right out of the box.
- Long-lasting performance design - engineered for repeated use across production runs, reducing tool change frequency and downtime on the shop floor.
Why This Product
- Profile flexibility without a new cutter head - because these knives are part of a large family of insert profiles for the universal cutter heads, shops can maintain a single cutter head body and simply swap knives to achieve different molding profiles, keeping tooling costs lower over time.
- Right-size format for common shaper setups - the 40x4mm (1-37/64 in. x 5/32 in.) knife size is a widely used insert dimension, making these knives compatible with CMT 692 series heads and other shaper systems that accept this knife format.
- Matched pair for balanced cutting - using a factory-matched pair of knives minimizes vibration and chatter during profiling passes, which translates directly to cleaner edges and better surface finish on finished parts.
- Alloyed steel for production durability - the alloyed steel material is well-suited for shops running molding profiles on hardwood, softwood, MDF, and chipboard, reducing the frequency of knife replacement in day-to-day production environments.
