This premium HSS step drill bit (4–32 mm) with a durable TiN coating is engineered for smooth drilling, deburring and countersinking in a single operation. The right-cutting, progressively fluted geometry ensures clean hole transitions, reduced vibration and optimal chip removal.
The TiN coating significantly increases the tool’s lifetime and heat resistance, making it ideal for frequent use in workshops, industrial environments and installation work across the DACH region (Germany, Austria, Switzerland).
Delivered in a robust metal storage case, the step drill is safely protected and ready for daily use on job sites, in workshops or for professional mobile service.
