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.

The set includes three HSS step drills in the versions 4–12 mm (9 steps), 4–20 mm (9 steps), 4–30 mm (14 steps) for industrial uses. To ensure reliable torque transmission, all step drills have a three-surface shaft. The sturdy plastic box protects the tools against dirt and damage. The securing of the HSS step drills facilitates the selection and withdrawal of the tools.

Advantages

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 blades 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.
