Advantages
  • Drilling and deburring in a single step.
  • Completely smooth running and a high cutting performance.
  • The high-quality drill tip ensures easy centering and drilling.
  • The tool taper makes it easier to pull back from drilled plates.
  • Long and solid chips are quickly and easily removed similar to the chip produced by a spiral drill.
  • Built-up edges and cold welding on the blades are prevented.
Recommendations for use
  • Use cutting oil/compressed air as a coolant and lubricant in the case of step drills without a coating.
Safety notes
  • To ensure reliable torque transmission, step drills have a three-surface shaft.
