Concave Quarter Round Milling Cutter with Radius R3 – R60 mm | HSS M2 / HW (K40)

🚀 DYNAMIC PROPERTIES AND PERFORMANCE:

• Optimal Top Radius Configuration: specifically designed for attacking and machining workpieces from above (right-hand operation) — a positioning that allows excellent visibility of the cutting line when working manually on classic routing machines.
• Full Range of Profiles (R3–R60): total production flexibility, from fine decorative R3 roundings to large and massive R60 profiles, used for posts, rustic furniture elements, or beams. Complete geometric details can be found in the technical drawing of each piece.
• Balanced HSS M2 Alloy (6.5% Tungsten): the sharp edge cuts the soft fibers of natural wood (spruce, fir, pine) cleanly, without tearing them and eliminating the risk of burn marks on the finished profile.
• T.C.T. Carbide for Composites: metallic carbide inserts resist the abrasive wear of synthetic binders in MDF, particleboard, and HDF, where HSS would wear prematurely.
• Anti-Shock Structural System: profiled inserts are industrially brazed with silver alloy (Ag), which acts as a cinematic shock absorber, dispersing vibrations during chipping and protecting the machine's bearings.
• Repeated Resharpening Guarantee: the constant geometry of the concave profile allows for multiple resharpenings directly on the face of the insert, without deforming the tool's radius.
• Custom Radius on Request: if your project requires a specific radius, outside the standard R3–R60 range, you can contact us with the technical drawing of your project.
