Tool Steel O1

O1 tool steel has good machinability but may require slower speeds and feeds compared to some other tool steels. CNC machining of O1 steel often involves pre- or post-machining heat treatment. The material is typically supplied in an annealed condition and needs to be hardened for use in tool applications. The usual heat treatment involves austenitizing at a specific temperature, followed by quenching in oil to achieve the desired hardness. When machining O1, we use carbide inserts because of their hardness and wear resistance. We also use high-speed steel (HSS) tools for less demanding conditions.

We carefully select cutting tool geometry and coatings to enhance tool life and surface finish. We put adequate flood coolant and lubrication to dissipate heat and enhance tool longevity. We regularly monitor tool wear during machining and make adjustments to cutting speed, feed rate, and depth of cut as needed to preserve optimal tool performance. O1 tool steel generally yields a good surface finish when machined correctly. Depending on the application, post-machining operations such as grinding or additional heat treatment may be required to achieve the desired material properties.
