Frequently Asked Questions

What is the OSG 4911900 roughing end mill used for?

The OSG 4911900 is a general purpose cobalt roughing end mill used for heavy material removal in industrial machining. It is designed for roughing operations on steel, stainless steel, and other ferrous alloys, providing efficient chip evacuation and reduced cutting forces.

What are the specifications of the OSG 4911900 roughing end mill?

The OSG 4911900 is a cobalt roughing end mill with 6 flutes, a 1-1/4 inch mill diameter, 4 inch length of cut, and 6-1/4 inch overall length. It is a general purpose tool suitable for roughing applications on ferrous materials.

Where to buy the OSG 4911900 roughing end mill worldwide?

You can source the OSG 4911900 roughing end mill through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring the tool reaches your facility reliably.

How to select the correct OSG roughing end mill for your application?

Select the OSG roughing end mill based on material type, required flute count, and cut dimensions. For heavy roughing on steel, a 6-flute cobalt end mill like the 4911900 with 1-1/4 inch diameter and 4 inch LOC is suitable. Match the tool to your machine's spindle speed and rigidity.
