  • 5 mm flute length reaches deep cavities

Tungsten Solid Carbide End Mill

The YINGHUA HRC55 tapered ball nose end mill is a solid carbide cutting tool built for industrial CNC milling and engraving. It is intended for professional workshops and operators aged eighteen or over who need a coated carbide cutter for precision profiling work.

55 HRC Hardness and 50 mm Overall Length

The cutter reaches a hardness of 55 HRC and measures 50 mm in total length with a 1.0 mm corner radius and a 20.5 mm taper length on a 4 mm shank. This geometry handles detailed contouring and finishing passes in hardened materials but does not suit heavy roughing or large-volume material removal.

Questions about this item

Will the R1.0 ball nose and 20.5 mm flute length reach the same depths in my older CNC router without changing the tool holder?

The cutter has a 50 mm overall length and a 20.5 mm flute length, so it reaches the same depths as any tool with those dimensions in your existing holder.

How can I confirm the HRC55 tungsten carbide coating is performing correctly after the first cuts?

Check for a smooth surface finish and consistent chip evacuation; the HRC55 hardness and tungsten carbide material should show minimal flank wear after the initial test pass.
