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.

- Version: HC-FEP
- Drill steps: 4.0/6.0/8.0/10.0/12.0/14.0/16.0/18.0/20.0
- Dia. shank, metric: 8 mm
- Drilling range, from: 4 mm
- Drilling range, to: 20 mm
- Length, total: 75 mm
Advantage:
- Drilling and deburring in a single step.
- Completely smooth running and a high cutting performance.
- The high-quality drill tip ensures effortless centring and drilling.
- The tool taper makes it easier to pull back from drilled plates.
- Chips which do not break are neatly removed as with a spiral drill.
Application:
- 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 especially well-suited to use on stainless steel (INOX).
