MITSUBISHI CARBIDE LJ293A New Products Solid carbide drill Large diameter sizes added. MZ drill Internal and external coolant, multi purpose high performance drill.
MZ drill, characteristics and application Wide groove shape gives excellent chip disposal. MZ Simple straight cutting edge design makes regrinding easy. GP with high wear resistance prolongs tool life. Solid carbide gives higher hole accuracy than HSS. 5 ~ 1 times higher efficiency tool life than HSS drill. Abundant standard inventory maintained. (Ø.78~ Ø.781) Grade is GP2M (tough substrate New PVD ) Straight X shape web thinning Sharp cutting edge with 3-rake faces.
