CMT Pair of Knives for Roundover and Chamfer (Top) - R=3mm 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 in a single pass, making edge shaping on hardwood, softwood, plywood, MDF, and chipboard faster and more consistent. The 3mm roundover blended with a 45 deg. chamfer on the top edge is a versatile profile choice for furniture, cabinetry, and architectural moulding work.

Key Features

• Carbide (HW) material construction - tungsten carbide holds a sharp cutting edge significantly longer than high-speed steel, reducing downtime for resharpening during production runs.
• Combined R=3mm roundover plus 45 deg. chamfer top profile - achieves two decorative edge effects in one pass, saving setup time and improving consistency across repeated cuts.
• 20mm diameter knife body - sized to fit compatible CMT spindle moulder cutter heads, ensuring secure seating and accurate profile alignment.
• 20mm cutting height - provides sufficient depth of engagement for full profile production on standard workpiece thicknesses used in moulding and edge-shaping applications.
• Sold as a matched pair - both knives are included together so the cutter head is always properly balanced, which is essential for safe, vibration-free operation at spindle speeds.
• Precision-ground profile - ground to exact specifications so the finished edge is accurate and repeatable from the first cut to the last, minimising waste and rework.

Why This Product

• The dual-profile geometry - 3mm roundover combined with a 45 deg. chamfer on the top edge - handles two of the most common decorative edge treatments in a single tool change, making it a practical choice for shops that run varied moulding or furniture profiles.
• Carbide (HW) construction means the knives maintain their cutting edge through extended production runs on dense hardwoods as well as engineered sheet goods like MDF and chipboard, reducing how often edges need to be reground.
• Because the knives are sold as a matched pair, the cutter head remains balanced as designed - eliminating the need to source individual blades separately or risk running an unbalanced assembly.
• With a 20mm cutting height, these knives engage the full intended profile depth cleanly on standard workpieces used in edging, profiling, and moulding operations - no partial cuts or stepped passes required for typical applications.
