CMT Multiradius Roundover Cutter Head by CMT is a precision-engineered shaper cutter head designed for spindle moulders, double-end tenoners, and shaper machines. With a 4-29/64 in. body diameter and a 1-1/4 in. bore, this cutter head accepts interchangeable knife sets to produce six distinct roundover radius profiles in a single tool - making it an exceptionally versatile solution for solid wood moulding, panel processing, and edge profiling on a wide range of wood-based materials.

Key Features

• Multiradius design supporting three different knife sets for six roundover profiles - one cutter head replaces multiple dedicated profile bits, reducing tooling costs and changeover time on the spindle moulder or shaper.
• Includes 2x HWM (hard metal) knives with 5 mm and 10 mm radii (25 x 24.8 x 2 mm, Z2) - ready to cut standard roundover profiles right out of the box without additional knife purchases.
• Two additional knife sets available separately covering radii of 4-8 mm and 3-6 mm - expands the cutter head to cover a full radius range of 3/16 in. to 25/64 in. for maximum shop versatility.
• Hard aluminium alloy body - lightweight yet rigid construction reduces spindle load while maintaining stability at operating speeds between 6,700 and 11,000 RPM.
• Suitable for solid wood, panel materials, and composite substrates - one tool handles production across hardwood, softwood, chipboard, MDF, and plywood without switching cutter heads.
• 2-knife (Z2) configuration - balances cutting forces for smooth, consistent roundover profiles and manageable feed rates on industrial shaper equipment.
• Cutting height of 63/64 in. - provides sufficient depth of engagement to complete roundover profiles cleanly in a single pass on typical solid wood and panel stock thicknesses.

Why This Product

• Six profiles from one tool head - because this cutter head supports three interchangeable knife sets producing six different radii, shops can standardize on a single 4-29/64 in. body rather than stocking multiple dedicated roundover bits, which directly reduces tooling inventory and setup time.
• Industrial speed range (6,700-11,000 RPM) matched to spindle moulder and double-end tenoner equipment - this is not a hand-router accessory but a purpose-built production tool sized and rated for the machines used in high-volume moulding and millwork operations.
• Interchangeable HWM knives allow rapid profile changes without replacing the cutter body - when production shifts from a 5 mm to a 10 mm roundover, only the knife set changes, keeping the heavy-duty aluminium alloy body in service and minimizing downtime.
• Radius range of 3/16 in. to 25/64 in. with optional knife sets covers the most commonly specified roundover profiles in furniture, cabinetry, and architectural millwork, making this cutter head a practical all-in-one profiling solution for solid wood and panel material edge work.
