Description
STEP step drill
  • For burr-free drilling and reaming of sheet metal, pipes and sections and one-sided deburring in a single operation
  • The exact bore diameter results from the cylindrical graduation, the ground section of each step deburrs the next smaller bore diameter
  • Point thinning in accordance with DIN 1412 C
  • Especially suitable for use on hand drills when drilling thin materials
  • Corner breakers for double-sided deburring (up to 1.5 mm sheets)
  • No need for pre-drilling or center punching even with curved surfaces
  • Straight shank with 3 driving planes prevents “slipping” in the chuck
  • Laser scaling of bore diameters and rotational speed data
  • Note: material thickness suitable up to 5 mm
