Insert Grade Selection
In 1984, Sumitomo Electric Hardmetal first released the MINI Tool Holder series for small product machining in small NC autolathes. A full range of insert grades including AC530U and AC1030U as well as Cermet T1500A, Carbide BL130, SUMIBORON BN2000, and SUMIDIA DA1000 are available to meet a variety of machining requirements. A high-precision grade, ACZ150, has been added to support a wide range of precision application requirements, from automotive to electronic component machining.
