Mill 4-11™ Shoulder Milling Inserts
Designed for smaller machining centers, the Mill 4-11 series of inserts accommodates 40-taper CAT and BT, HSK 50, and similarly-sized spindles. Due to its free-cutting capabilities, it is ideal for successful metal removal in less-than-rigid setups and on light-duty machine tools, multitaskers, and live-tool lathes. The Mill 4-11 strong insert design offers an 11 mm (0.433 in.) maximum cut length, addressing the needs of job shops and manufacturers. The inserts are also easy to use. Each insert is securely locked in place with a single M3 screw and marked with a series of dimples to indicate geometry and insert style.
