Frequently Asked Questions

What is an OSG square end mill used for?

An OSG square end mill is used for general-purpose milling operations such as slotting, profiling, and contouring in metalworking. Its square cutting edge produces 90-degree shoulders and flat-bottomed slots. It is suitable for machining a wide range of materials including steel, stainless steel, and cast iron.

What are the specifications of the OSG 402-3150 end mill?

The OSG 402-3150 is a carbide square end mill with 2 flutes, an 8 mm mill diameter, 21 mm length of cut, and 64 mm overall length. It is designed for general-purpose milling and is manufactured by OSG. 3G Electric supplies this genuine OSG part and can source it for worldwide delivery.
