YINGHUA HRC55 Tapered Ball Nose End Mill

The YINGHUA R1.0x15xD4x50L is a tungsten solid carbide milling cutter with a coated tapered cone profile. It is designed for CNC milling operations requiring a right-angle drill type tool. The cutter features a hardness rating of HRC55 for wear resistance during industrial cutting and engraving tasks.

Suited for CNC operators machining hardened

This tool suits machinists performing detailed 3D contouring or finishing passes where a tapered ball nose geometry is required. It is not intended for buyers needing a flat end mill, a larger shank diameter than those listed, or a cutter for non-industrial hobby use. The safety instructions specify it is not for people under 18 years old.

Single cutter supplied in basic packaging

The package includes one ball nose end mill ready for immediate use in a compatible CNC spindle. No additional accessories, collets, or software licences are bundled. The operator must provide appropriate tool holding and coolant strategy for the specific workpiece material.

Questions about this item

What shank diameter must my CNC machine's collet accept for the 15 mm tapered length cutter?

The tool is offered with 3.175 mm, 4 mm, 6 mm and 8 mm shank options; choose the one that matches your collet size.

Can I run this HRC55 carbide mill in the same holder as my older HSS end mills?

Yes — the shank diameters are standard sizes, so the mill fits existing ER or collet chucks, but reduce feed rates because carbide is more brittle than HSS.

How do I verify the 1.0 mm ball nose radius is cutting correctly after setup?

Inspect the first workpiece for a smooth 1.0 mm radius contour and listen for steady spindle sound; chatter or faceted curves indicate incorrect speed or run-out.
