Frequently Asked Questions

What is an OSG roughing end mill used for?

An OSG roughing end mill is used for high-speed material removal in machining operations. It efficiently cuts steel, stainless steel, and other alloys, leaving a rough surface finish that is later refined with a finishing end mill. This tool is common in mold making, die work, and general industrial machining.

What are the specifications of the OSG 4727100 roughing end mill?

The OSG 4727100 is a general purpose cobalt roughing end mill with 6 flutes, a 2-inch mill diameter, 6-inch length of cut, and 9-3/4-inch overall length. It is designed for aggressive material removal in ferrous metals and is suitable for CNC and manual milling machines.

Where to buy OSG roughing end mills worldwide?

How to select the right roughing end mill for my application?

Select a roughing end mill based on material hardness, required stock removal rate, and machine rigidity. For general steel machining, a cobalt roughing end mill like the OSG 4727100 with 6 flutes offers good chip evacuation and durability. Match flute count to material: fewer flutes for softer materials, more for harder alloys.
