Description

HSS step drills for drilling and deburring thin sheets, pipes and profiles made from various materials. To ensure reliable torque transmission, all step drills have a three-surface shaft. HSS step drills with premium HICOAT® coating HC-FEP are wear resistant and versatile as they can be used to process steel, stainless steel (INOX), non-ferrous metals, thermoplastics and duroplastics. Step drills with HICOAT® coating HC-FEP provide good high-temperature hardness and resistance to oxidation. They can therefore also be used on hard materials without the addition of coolants.
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 HSS step drills on sheets, pipes and profiles with a maximum thickness of 4 mm.
  • Step drills with a HICOAT® coating can also be used without the addition of coolants.
  • Step drills with a HICOAT® coating are ideal for use on stainless steel (INOX).
