The SX Series Face Mill has free cutting positive geometry which is ideal for all gray cast iron materials and the stepdex configuration generates metal removal rates up to 2 inchł per minute per unit of horsepower. The stepdex configuration provides excellent force and load management during overextended or weak setups. Self-locating precision anvils provide quick accurate indexes and little down time. Lovejoys LTC-1200 silicon nitride material operates in the advanced range machining parameters.
