YINGHUA HRC55 Tapered Ball Nose End Mill

This tungsten steel end mill is designed for industrial CNC milling and engraving tasks. The coated tapered ball nose cutter features an R0.25 radius with a 20.5 mm cutting length and 4 mm shank diameter. It is supplied as a single piece for professional machining operations. The product is restricted to users aged 18 years and over.

Replaces worn or lower-hardness ball nose cutters

Upgrading to this HRC55 carbide tool is worthwhile when the current cutter shows reduced edge retention or poor surface finish on hardened materials. The higher hardness rating extends tool life in demanding milling applications. Buyers who need multiple cutters for batch production or different radius profiles should note this listing includes only one piece.
