YINGHUA R1.0x30.5xD6x75L HRC55 Tapered Ball Nose End Mill

CNC Milling Cutter for Industrial Engraving

This solid carbide end mill is built for precision contouring and finishing on CNC machines. Its tapered ball nose geometry suits 3D profiling and detailed engraving work in a workshop environment. The cutter is intended for industrial use only and must not be handled by anyone under eighteen years of age. It arrives ready for direct installation into compatible tool holders.

Shank Options and Length Range for Tool Holders

The tool is offered with shank diameters of 3.175 mm, 4 mm, 6 mm and 8 mm to match common collet sizes. Overall lengths span from 38 mm to 100 mm, allowing selection based on machine clearance and reach requirements. Choosing the correct shank and length combination frees up rigidity and reduces the need for extended tooling setups. No other mounting hardware is required beyond a standard ER or shrink-fit holder.

Single-Piece Package for Immediate Use

Each package contains one coated tungsten steel ball nose end mill with an R1.0 tip radius, 30.5 mm taper length, 6 mm major diameter and 75 mm overall length. The HRC55 hardness and protective coating are designed to extend tool life during continuous cutting cycles. No additional accessories, software or documentation are included in the box.
