YINGHUA HRC55 Carbide End Mill

This single-flute tapered ball nose cutter is made from tungsten steel with an HRC55 hardness rating. It measures 75 mm in overall length and features a 30.5 mm cutting section on a 6 mm shank. The coated carbide construction is intended for CNC milling operations in industrial environments.

Suited for precision 3D contouring

Machinists producing complex curved surfaces in hardened materials will benefit from the tapered profile and ball nose geometry. The tool is restricted to users aged 18 and over and is not designed for handheld drilling or general-purpose fastening tasks. Buyers needing a standard twist drill or a flat-bottom end mill should consider other tool types.

Questions about this item

How do I confirm the cutter is performing correctly after installing it in my CNC machine?

Verify the tool runs true at the rated 55 HRC hardness and produces a smooth radius of .5 mm without chatter or excessive flank wear during the first test cuts.

What exactly ships in the package and what additional items must I source separately?

The box contains one tungsten-steel tapered ball-nose end mill with 30.5 mm flute length, 6 mm shank and 75 mm overall length; you must supply the collet, tool holder and any coolant or dust-extraction system yourself.
