HSS multi diameter step drills produce good quality holes in a wide variety of sheet metal, using either a bench drill or light pedestal drilling machine. Manufactured from high speed steel, they offer sound rigidity, strength and stability when machining. Each tool cuts parallel holes in a range of specific sizes and is compatible with materials up to 1/8" (3mm) thick.

Features and Benefits
• High speed steel construction for greater strength, rigidity and stability
• Excellent wear and heat resistance for prolonged tool life
• Cuts parallel holes in sheet metal

Typical Applications
• Drilling
• Sheet metal

Notes
• Available sizes 1-12mm to 6-37mm
