Precision Tapered Ball Nose End Mill

The YINGHUA R0.5x15xD3.175x38L HRC55 is a tungsten solid carbide coated tapered cone CNC milling cutter designed for industrial cutting and engraving. Its right-angle drill configuration and HRC55 hardness suit detailed 3D profiling in hardened materials. The shank diameter of 3.175 mm fits compatible precision collets.

For Detailed CNC Engraving Work

This cutter suits machinists producing fine contours, mould cavities or intricate reliefs where a 0.5 mm radius tip and 15 mm taper length are required. It is not for operators under 18 years of age. Buyers needing larger shank diameters such as 4 mm, 6 mm or 8 mm or total lengths beyond 100 mm should select a different tool.

Consistent Carbide Performance Under Load

Tungsten steel construction with a protective coating maintains edge integrity during sustained CNC milling passes. The HRC55 rating resists wear when cutting abrasive or hardened workpieces over long runs. Heat buildup stays controlled, reducing the risk of premature tip breakdown in continuous operation.

Questions about this item

What shank diameter must my CNC collet or holder accept for the 3.175 mm shank on this end mill?

The tool has a 3.175 mm shank, so your machine needs a collet or chuck that grips that exact diameter.

Will the 38 mm overall length fit in the same tool holder I use for longer 100 mm cutters?

Yes, the 38 mm length is shorter than the 100 mm maximum, so it will seat in any holder that accommodates the longer tools.

How can I confirm the HRC55 hardness is performing correctly after the first cuts?

Check for clean edges, minimal flank wear and consistent chip formation in the workpiece after the initial passes.
