YINGHUA R0.5 Tapered Ball Nose End Mill

The YINGHUA R0.5x30.5xD6x75L is a solid tungsten carbide milling cutter coated for hardness rated at HRC55. It features a tapered ball nose geometry with a 30.5 mm flute length and 75 mm overall length. The tool is designed for CNC milling operations requiring precise contouring and finishing passes.

Suited for industrial engraving

This cutter serves machinists and fabricators performing fine detail work on hardened materials in a professional workshop. The bladed product is restricted to users aged 18 and over and is intended solely for industrial cutting and engraving tasks. It is not suitable for hobbyists seeking general-purpose drill bits or operators needing tools for non-industrial applications.

6 mm shank diameter for compatible tool holders

The cutter uses a 6 mm shank dimension taken from the available specification range of 3.175 mm, 4 mm, 6 mm and 8 mm. Select this shank size to match the collet or holder fitted to your CNC spindle. Total length varies between 38 mm and 100 mm across the product line, so verify the 75 mm overall length meets your machine’s clearance requirements.

Questions about this item

What shank diameter must my CNC machine's collet or tool holder accept for this 6 mm shank cutter?

This cutter has a 6 mm shank, so the machine's collet or holder must grip a 6 mm diameter.

Can I run this HRC55 carbide end mill in the same job as older high-speed-steel tools without changing spindle speed?

Carbide tolerates higher surface speeds than HSS, so you will need to raise the spindle rpm or reduce feed when switching to this cutter.

How can I confirm the 0.5 mm corner radius is cutting correctly after the first pass?

Measure the fillet radius on the workpiece with a radius gauge or calibrated probe; it should match the 0.5 mm spec.
