YINGHUA 13x50MM HRC45 Altin Coated Carbide Roughing End Mill

YINGHUA HRC45 Altin Roughing End Mill

This 4-flute solid carbide cutter is built for CNC roughing passes in aluminium cast iron, steel, stainless steel and copper. The Altin coating and HRC45 substrate target workshops that need fast material removal without frequent tool changes. It suits machinists running aggressive feeds on rigid machines. Buyers needing fine finishing profiles or non-ferrous-only geometry should select a different tool.

Sustained Load Behaviour

The HRC45 carbide core resists deformation when the spindle dwells in deep slots or heavy pocketing cycles. Altin coating reduces built-up edge during long cuts in stainless steel and copper, keeping chip evacuation consistent. Heat dissipates through the solid carbide body rather than concentrating at the flute tips. Shops without high-pressure coolant or rigid workholding may see reduced tool life.

Build Quality and Mounting

Raw tungsten steel bar stock is ground to a 13 mm cutting length with a 50 mm overall reach, giving a stiff shank-to-flute transition. The 5 mm shank diameter fits standard ER collets and shrink-fit holders without adapters. Separate packaging protects the coating from handling damage before first use. Users requiring longer reach or smaller shank diameters will need alternative tooling.
