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.

Advantages

Drilling and deburring in a single step.
Completely smooth running and a high cutting performance.
The high-quality drill tip ensures easy centering and drilling.
The tool taper makes it easier to pull back from drilled plates.
Long and solid chips are quickly and easily removed similar to the chip produced by 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.
Step drills with a HICOAT® coating can also be used without the addition of coolants.
Step drills with a HICOAT® coating are ideal for use on stainless steel (INOX).
