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.
