YINGHUA HRC55 Carbide End Mill for CNC Machining

This solid tungsten carbide cutter features a tapered ball nose profile with a 0.25 mm corner radius and a 15 mm taper length. The shank diameter is 3.175 mm and the overall length measures 38 mm. It is supplied as a single piece for precision milling and engraving tasks in industrial environments.

Sustained Cutting Performance with HRC55 Hardness

The HRC55 coating maintains edge integrity during extended CNC runs, reducing wear when profiling deep cavities or contoured surfaces. Heat buildup is managed by the solid carbide substrate rather than by forced cooling. The tool is not intended for hand-held drilling or for operators under 18 years of age. Buyers needing a larger radius or a different shank size should select another model.

Questions about this item

How much heat does the HRC55 tapered ball nose end mill generate during extended CNC runs?

The solid carbide construction and coating help dissipate heat efficiently, but sustained cutting speed and coolant use determine actual temperature rise.

What shank size must my CNC collet or holder accept for this 3.175 mm diameter tool?

The end mill has a 3.175 mm shank, so your collet or holder must grip that exact diameter for secure clamping.
