Description

Version:

  • HSS

Description:

  • HSS step drills for drilling and deburring thin sheets, pipes and profiles made of various materials.
  • All step drills are equipped with a three-surface shank for secure torque transmission.
  • Adapted to the common diameters of cable pipe fittings.

Feature:

  • Number of drill steps: 11 pieces
  • RPM of, hard NF metals: 180 rpm
  • RPM of, rust and acid resistant steels: 90 rpm
  • RPM of, soft NF metals: 180 rpm
  • RPM of, steels up to 700 N/mm²: 180 rpm
  • RPM of, Thermoplastics, Fiber Reinforced Plastics (GRP/CFRP): 90 rpm
  • RPM BIS, hard NF metals: 1400 rpm
  • RPM BIS, rust and acid resistant steels: 920 rpm
  • RPM BIS, soft NF metals: 1400 rpm
  • RPM BIS, steels up to 700 N/mm²: 1400 rpm
  • RPM BIS, Thermopl. Plastics, fibrous Plastics (GRP/CFRP): 920 rpm
  • Version: HSS
  • Drill steps: 7/32.5,5/12,5/14,5/10,20/18,5/5,5/16,5/25,5/30,5/23
  • Ø Metric shaft: 12 mm
  • Drilling range, from: 7 mm
  • Drilling range, to: 32.5 mm
  • Length, total: 96.5 mm

Advantage:

  • Drilling and deburring in just one step.
  • Absolute smoothness and high cutting output.
  • Effortless centering and drilling through high-quality drill tip.
  • Facilitated retraction of through-drilled sheets by means of tool cone.
  • Non-breaking chips are removed cleanly, as with a spiral drill.

Application:

  • Application recommendations: Use HSS step drills on sheets, pipes and profiles up to a maximum material thickness of 4 mm. For step drills without coating, use cutting oil or compressed air as coolants/lubricants.
