PFERD Step drill HSS 9 drilling steps dia. 4-12 mm 3-surface shaft dia. 6 mm HICOAT coated
Characteristics
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 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.
