Tungsten Carbide Tapered Ball Nose End Mill

The YINGHUA R0.75x20.5xD6x50L is a solid carbide milling cutter coated for CNC engraving and contouring. It is built for machinists and fabricators who need precise 3D profiling in hard materials. The HRC55 hardness rating supports aggressive cutting parameters. This tool is not for hand-held drilling or general-purpose fastening tasks.

Fits Standard CNC Collets And Holders

The 6 mm shank diameter seats directly in common ER collets and shrink-fit holders without adapters. A 50 mm overall length clears deep cavities while keeping overhang short for rigidity. The tapered cone geometry reaches angled walls that straight end mills cannot access. It requires a capable CNC spindle with runout control; it is not suited for manual drill presses.

HRC55 Carbide Holds Edge In Extended Cuts

Tungsten steel construction resists deflection and heat buildup during long contouring passes. The coating reduces friction and chip welding when profiling steel or hardened alloys. Consistent flute engagement prevents chatter in deep pockets. The tool is rated for industrial use only and must not be operated by anyone under 18 years of age.

Questions about this item

How long is the cutting section before the shank?

The tapered ball nose section measures 20.5 mm from tip to transition.

What spindle speed range keeps the carbide cool during long CNC runs?

Run the tool at the feed and speed your machine manual recommends for HRC55 tungsten carbide to limit heat buildup.

Which collet size matches the 3.175 mm shank option?

Use a 3.175 mm (1/8 inch) ER collet or shrink-fit holder for that shank diameter.
