YINGHUA HRC55 Carbide End Mill

The YINGHUA R1.0x20.5xD6x50L is a solid tungsten carbide cutter with a tapered ball nose profile. It is designed for CNC milling operations requiring precise contouring and 3D profiling in hardened materials up to HRC55 hardness.

6 mm Shank Fits Standard Collets

The cutter uses a 6 mm shank diameter compatible with common ER collet systems and shrink-fit holders. Ensure the tool holder is rated for carbide shanks and that run-out is minimised; excessive vibration will chip the coating and reduce tool life.

1.0 mm Radius Defines Corner Geometry

The 1.0 mm ball nose radius determines the minimum internal fillet and surface finish achievable in a single pass. Buyers needing larger corner radii or flat-bottom pockets must select a different tool profile.
