Threading Holders (Work Pieces / Corner)Tool Life Threading Tools Threading Insert General Features Dimple breaker Indexable inserts l A positive rake angle encourages good chip TME type for external control and reduces cutting resistance. threading l Two tier dimple-style chip breakers evacuate chip smoothly and easily. l M-class tolerance reduces insert cost. New sintered threading insert with special dimple shaped chip breaker l Four available grades cover a wider range of applications. l The LTER type holder is designed for easy Comparison of Chip Control clamping and replacement.
