Key Features
- Alloyed Steel Construction - made of alloyed steel for long-lasting cutting performance through repeated use in demanding production and shop environments.
- 40x4mm Knife Size (1-37/64 in. x 5/32 in.) - precise dimensions ensure a consistent profile cut every time, reducing tearout and the need for excessive sanding.
- Compatible with Universal Cutter Heads - fits a variety of CMT universal cutter heads, so one set of cutter heads can serve multiple profiles simply by swapping knives.
- Pair of 2 Knives Included - both knives are matched and supplied together, so setup is straightforward and balanced cutting is maintained from the start.
- Profile Number 133 - Available in Multiple Radius Options (4mm, 6mm, 8mm) - the range of available radius options within this profile family gives woodworkers the flexibility to match the right curve to their specific project without changing systems.
Why This Product
- Woodworkers who already use CMT universal cutter heads can expand their profile repertoire without investing in additional cutter head bodies - simply change the knives to change the profile.
- The alloyed steel material ensures the cutting edge holds up through extended runs on hardwood and softwood alike, reducing downtime for sharpening or replacement.
- Selling as a matched pair means both knives are ready to install together, keeping the cutter head balanced and producing a clean, smooth surface on moldings, frames, and cabinet door edges.
- Multiple radius options (4mm, 6mm, and 8mm) within this profile system give shops the ability to dial in the right look for different applications - from subtle eased edges to more pronounced decorative profiles.
