Frequently Asked Questions

What is the OSG 5265100 ball end mill used for?

The OSG 5265100 is a reduced-neck cobalt ball end mill designed for contouring, 3D profiling, and die/mold machining. Its ball nose shape creates smooth curved surfaces, making it ideal for aerospace, automotive, and general metalworking applications requiring precision radii and fine finishes.

What are the specifications of the OSG 5265100 ball end mill?

The OSG 5265100 is a 2-flute, cobalt ball end mill with a 1" mill diameter, 2-1/2" length of cut, and 7-1/4" overall length. The reduced-neck design provides clearance for deep cavity machining. Cobalt construction offers heat resistance for cutting hardened steels and high-temperature alloys.

Where to buy the OSG 5265100 ball end mill worldwide?

3G Electric supplies the OSG 5265100 ball end mill worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time; we source and deliver this OSG tool to any international destination.

How to select the right OSG ball end mill for your application?

Select an OSG ball end mill based on material hardness, required finish, and depth of cut. For the 5265100, use its 1" diameter for roughing or semi-finishing in steels and alloys. Match flute count (2-flute for chip evacuation) and cobalt grade for heat resistance. Consult OSG's technical data for optimal speeds and feeds.
