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.

Special features

• 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 HSS 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.
