YINGHUA HRC55 Tapered Ball Nose Cutter

This YINGHUA tapered ball nose end mill is made from tungsten solid carbide and rated HRC55 for hardness. It is intended for CNC milling and engraving work in industrial settings. The cutter suits machinists and fabricators who need a coated carbide tool for contouring and finishing operations.

Shank options and coating implications

The tool is offered with shank diameters of 3.175 mm, 4 mm, 6 mm and 8 mm to fit various collets and holders. A total length range of 38 mm to 100 mm allows selection for reach and rigidity requirements. The coated carbide construction resists wear during prolonged cutting cycles.

Application limits and safety

The product is designated for industrial cutting and engraving only and must not be used by anyone under 18 years of age. It is not a general-purpose drill bit and cannot substitute for tools designed for other materials or operations. Buyers needing non-coated geometry or different taper angles should select another tool.
