End mill OSG

OSG is pleased to present our first-class line of Cobalt (HSS-Co) end mills. Our HSS-Co end mills have a higher hardness range than regular High-Speed Steel (HSS) end mills due to an 8% cobalt content, which results in increased tool life and overall performance.

HSS-Co end mills are designed to mill difficult-to-machine materials, and are more forgiving than carbide tooling. Where carbide has a tendency to break or chip in less rigid operations, HSS-Co is ideal for such applications.

OSG uses a premium HSS-Co substrate, while some competitor products utilize a more basic grade of HSS, resulting in reduced hardness and a decreased selection of materials for which their tools can be effective.
