    D1 1" D2 1" OAL 4" LOC 1-1/2" Radius .030" or .060" 4-flute Ballnose and Radius End Mills perform exceptionally well in most ferrous materials. They are also used with great success on Stainless Steel when coated with InoxoCon. They are intended for applications using Trochoidal or High-Speed Milling operations and feature a 40° Helix. AlTiN offers very good performance in harder materials and is good in high speed milling operations. For improved tool life and performance we recommend FerroCon coating for all steels and steel alloys especially tool steel. For Stainless Steel milling we recommend InoxoCon. In the materials they are made to operate in the FerroCon and InoxoCon will dramatically improve the capability of the end mills over the standard coatings.
