YINGHUA Solid Carbide Roughing End Mill

This YINGHUA solid carbide roughing end mill measures 12x12x30x75MM with four flutes and an Altin coating. It is manufactured from raw solid tungsten steel with a hardness of HRC45. The tool is designed for CNC milling operations on aluminum cast iron, steel, stainless steel, and copper.

Suited for roughing passes on listed metals.

The roughing geometry removes material quickly on the specified metals. Machinists needing a fine surface finish or tight tolerances should select a finishing end mill instead. This cutter is not intended for non-metallic materials such as wood, plastics, or composites.

4-flute Altin-coated carbide with HRC45 hardness

The four-flute design combined with the Altin coating and HRC45 substrate determines chip evacuation and heat resistance during heavy roughing cuts. Verify that your machine spindle and holder accommodate the 12MM shank and 75MM overall length before purchase.

Questions about this item

How hot does the 12 mm solid carbide body get during extended roughing in steel?

The HRC45 tungsten carbide substrate and Altin coating are designed to handle the heat generated when roughing steel, cast iron and stainless steel at recommended feeds.

What holder or machine interface is required for the 12 mm shank?

The 12 mm cylindrical shank fits standard ER collets, Weldon flats or shrink-fit holders on any CNC mill or router with a matching collet size.

Will the 4-flute geometry and Altin coating work on an older manual knee mill?

Yes, the right-hand roughing profile cuts aluminum, steel and stainless steel on conventional machines, though rigid CNC setups give the best chip evacuation.
