Frequently Asked Questions

What is the OSG Corner Radius End Mill 44450004 used for?

This OSG carbide end mill is designed for machining hardened materials up to 65 HRC. The WXL coating reduces heat and wear, while the 0.02" corner radius strengthens the cutting edge to prevent chipping, making it suitable for finishing and semi-finishing operations in tool and die work.

What are the specifications of the OSG 44450004 end mill?

The OSG 44450004 is a carbide corner-radius end mill with WXL coating, 4 flutes, 3/16" mill diameter, 3/4" length of cut, and 0.02" corner radius. It is designed for hardened materials and comes with a 3/16" shank diameter. The manufacturer part number is 44450004.

Where to buy the OSG 44450004 end mill worldwide?
