55 series- Solid Carbide Corner Radius Endmill

The 55 series corner radius endmill is a precision milling cutter engineered for high-performance finishing and roughing in mold-base machining and tool steel work. Combining the surface-finishing finesse of rounded corner geometry with the flat-bottom capability of a traditional endmill, the HRC55 delivers superior edge strength, excellent surface integrity, and smooth transitions—ideal for demanding CNC operations.

Geometry & Benefits

• Corner-radius edge profile: Offers increased edge strength, reduces chipping, and improves part aesthetics compared to sharp-corner cutters—especially important in high-wear mold and die applications.

• Flat-bottom endmill design: Retains the capability for helical cutting and flat-surface machining—unlike ball-nose cutters—enabling precise contour transitions and clean finishes.

• Solid carbide substrate: Offers the rigidity, wear resistance, and thermal stability required for tight tolerance finishing and roughing tasks.

• Optimized for mold-base work: Particularly suitable for roughing mold cavities and side finishing in steels and tool steels, where both surface quality and tool life matter
