CMT Multiradius Roundover Cutter Head by CMT is an industrial-grade shaper cutter head engineered for spindle moulder machines, double-end tenoner machines, and shaper machines. Designed to support two interchangeable knife sets, this cutter head produces four distinct roundover radius profiles in a single tool body - making it a highly versatile solution for furniture makers, millwork shops, and production woodworking operations that require consistent, repeatable edge profiles across solid hardwood, softwood, and engineered wood panels.

Key Features

• Multiradius design supporting two different knife sets - a single cutter head body produces four roundover profiles, reducing the need to purchase and store multiple dedicated heads and cutting downtime between profile changes.
• Standard knife set included for 15mm and 20mm radii - delivers two of the most commonly specified roundover sizes right out of the box, allowing immediate production use on spindle moulder and shaper machines.
• Optional additional knife set available for 12mm and 18mm radii - expands the range of achievable profiles to four distinct roundovers without requiring a second cutter head body, supporting flexible shop production runs.
• 5-13/64 in. diameter cutter head body - the large working diameter provides stability and smooth cutting action, reducing vibration and improving edge quality on solid hardwood and engineered panels alike.
• 1-25/32 in. cutting height - sufficient vertical capacity to engage thick workpieces and produce full-depth roundover profiles on cabinet doors, mouldings, and furniture components in a single pass.
• 19/32 in. - 25/32 in. radius range (standard knives) - covers mid-to-large roundover profiles suitable for heavy-duty edge profiling, industrial moulding production, and raised panel work.
• Hardmetal (HW) carbide cutting material - delivers long tool life and consistent edge quality when machining abrasive materials such as MDF, chipboard, and laminates in addition to natural wood species.
• 1-1/4 in. (31.75mm) bore diameter - fits standard industrial spindle moulder and shaper machine spindles, ensuring secure, runout-free mounting for precision profiling results.
• Operating speed range of 5,700 - 9,500 RPM - a defined safe speed window that accommodates both lower-speed heavy-stock removal and higher-speed finish passes, giving operators flexibility to tune feed rates for optimal surface quality.
• 2-tooth (2-knife) configuration - balanced cutting geometry distributes cutting load evenly across the workpiece, contributing to smooth profiles and reduced machine stress during production runs.

Why This Product

• Four profiles from one tool body - by accepting two interchangeable knife sets, this cutter head eliminates the cost and storage overhead of maintaining four separate profile cutters. Shops running varied roundover specifications benefit immediately from the built-in flexibility.
• Built for production-grade machines - rated for spindle moulder, double-end tenoner, and shaper machines, this cutter head meets the demands of industrial woodworking environments where throughput, repeatability, and spindle compatibility are non-negotiable requirements.
• Expandable profile capability through optional knife sets - the availability of a second knife set (12mm and 18mm radii) means the tool can grow with a shop's profile requirements without replacing the head body, protecting the initial tooling investment.
• Hardmetal carbide construction for material versatility - the HW carbide cutting material handles a broad range of substrates from solid hardwoods to MDF and laminates, making this cutter head a dependable choice for shops that run mixed material workflows on the same machine.
