Frequently Asked Questions

What is an OSG square end mill used for?

An OSG square end mill is used for precision milling operations such as slotting, profiling, and contouring in metalworking. Its square tip creates sharp 90° corners, making it ideal for die and mold making, aerospace, and automotive applications where tight tolerances are required.

What are the specifications of the OSG 447-3750 end mill?

The OSG 447-3750 is a carbide square end mill with 4 flutes, a 3/8" mill diameter, 1" length of cut, and 2-1/2" overall length. It features a left-helix design for improved chip evacuation in certain materials. 3G Electric supplies this genuine OSG tool worldwide.

Where to buy OSG 447-3750 end mills worldwide?
