Multi-Step Drills – HSS DM O5 More precise hole diameter through cylindrical steps. Hole deburring through the next step. Standard execution with 2 chip spaces, spiral grooved. n More precise hole diameter through cylindrical steps. n Immediate deburring through the next step n Drilling of sheet metals as thin as 4 mm possible. n Use coolant stick! n The keyway allows the drill to make a chipping cut during drilling for better chip removal.
