Product description

PFERD step drill HSS 14 drilling steps dia. 4-30mm 3-surface shaft dia. 10mm 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.
