Description

HSSE step drill 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.

Advantages

Long tool life and temperature resistance due to Co content.
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.
Built-up edges and cold welding on the flutes are prevented.

Recommendations for use

Use HSSE step drills on sheets, pipes and profiles with a maximum thickness of 4 mm.
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.
