TUNGCUT – Pulley – AH725


DGM type demonstrates remarkable chip control even when machining Fe360 material, which has difficult chip control. This is possible because DGM type breaks chips into smaller pieces credit to well-designed chipbreaker. DGM type significantly improves productivity since it allows higher feed than the competitor and the fact that it does not require step-feed. AH725’s excellent wear resistance doubles the tool life.
