CMT Pair of Knives for Roundover and Chamfer (Top) - R=6mm plus 45 deg. are precision-ground carbide profiling knives designed for shaping clean roundover and chamfer profiles on the top edge of workpieces. Engineered from hard metal (HW) carbide, these matched knives deliver consistent, repeatable results across a wide range of wood-based materials including hardwood, softwood, plywood, MDF, and chipboard. Whether you are running a spindle moulder, shaper, profiling machine, or edging machine, these knives are built to integrate with CMT cutter heads and produce crisp, professional-quality profiles in demanding production environments.

Key Features

• Dual profile - R=6mm roundover plus 45 deg. chamfer (top edge): two complementary profiles in one pair of knives, giving woodworkers flexibility to achieve a smooth rounded edge or a crisp angled chamfer without swapping tooling.
• Hard metal (HW) carbide construction: carbide material maintains a sharp cutting edge longer than high-speed steel alternatives, reducing downtime for resharpening and keeping production moving efficiently.
• Precision-ground profile to exact specifications: each knife is ground to match the stated R=6mm radius and 45 deg. angle, ensuring accurate, repeatable profiles pass after pass with minimal setup adjustment.
• Sold as a matched pair: both knives in the set are ground and balanced together, promoting smooth, vibration-reduced cutting and consistent profile depth across the full cut width.
• 20mm cutting height: provides sufficient depth of cut for edge profiling applications on standard stock, reducing the need for multiple passes on typical workpiece thicknesses.
• Compatible with spindle moulders, shapers, profiling machines, and edging machines: broad machine compatibility means these knives fit into existing workshop tooling setups without requiring dedicated equipment.

Why This Product

• The combined R=6mm roundover plus 45 deg. chamfer profile on a single pair of knives handles two of the most common edge treatments in furniture and millwork production, reducing the number of tooling changes needed during a workflow.
• Carbide (HW) construction means the cutting edges hold up through long production runs on demanding materials such as MDF, chipboard, and hardwood - materials that would quickly dull lesser tooling.
• Because both knives in the pair are precision-ground together, they are balanced for use as a set, helping to minimize vibration and surface chatter that can cause tearout or uneven profiles.
• The top-edge chamfer and roundover geometry specifically addresses shaping the upper face of a workpiece, making these knives the appropriate choice when a top-profile treatment is required rather than a full edge profile from both directions.
