Product Description
CMT Pair of Knives for Roundover and Chamfer (Top) - R=4mm plus 45 deg. by CMT are precision-ground carbide profiling knives designed for spindle moulders, shapers, profiling machines, and edging machines. This matched pair delivers a combined roundover and chamfer profile on top edges, making them a practical choice for furniture makers, cabinetmakers, and millwork professionals who need clean, repeatable edge profiles on hardwood, softwood, plywood, MDF, and chipboard.
Key Features
- Dual-profile geometry - R=4mm roundover plus 45 deg. chamfer (top): combines two edge treatments in a single knife pair, so you achieve both a softened roundover and a crisp chamfer angle in one pass without changing tooling.
- Carbide (HW) material: tungsten carbide construction resists wear and retains a sharp cutting edge far longer than standard steel knives, reducing downtime between sharpenings on demanding production runs.
- 20mm cutting height: provides adequate depth of cut for profiling solid wood and engineered panels in a single pass, improving workflow efficiency on spindle moulders and shapers.
- 20mm diameter profile knives: sized to fit CMT spindle moulder cutter heads, ensuring precise, consistent engagement with the cutter body for safe and accurate operation.
- Sold as a matched pair: both knives in the set are ground to identical profile specifications, so balance and symmetry are maintained in the cutter head - critical for smooth, chatter-free cuts and a quality finished surface.
- Precision-ground profile: each knife is ground to exact profile dimensions, delivering accurate, repeatable results across production volumes in moulding, profiling, and edge shaping applications.
Why This Product
- For woodworkers who need to run a roundover and a 45 deg. chamfer on the same top edge, this pair eliminates the need for two separate knife sets - saving setup time and tooling cost on spindle moulders and shapers.
- The HW carbide construction is well suited to demanding materials like MDF and chipboard that quickly dull less durable tooling, helping maintain edge quality through longer production runs.
- Matching the knives as a pair ensures balanced loading in the cutter head, which reduces vibration and contributes to a cleaner surface finish on profiled and moulded workpieces.
- The 20mm cutting height gives these knives enough depth to handle typical solid wood and panel profiling tasks in one pass, supporting efficient operation on profiling machines and edging machines alike.
