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 | | Specifications | HSS | Uncoated | | Typical Applications | Drilling | Sheet metal | | Notes | Available sizes 1-12mm to 6-37mm
