HSS Step Drill Bits are perfect for drilling multiple-size holes in thin sections of metal, plastic and wood using a single bit.
 
Each step drills does the work of many drill-bit sizes. Drills round holes in most metals (steel, brass, aluminum, copper) up to 1/8" (3.2mm) thick as well as in plastic and wood.
 
No center punching or pilot hole drilling is required on most sizes. The bits are easy to keep sharp,  and the hole size is easily determined by the diameter markings that are permanently laser-etched in the flute area.


Step drills are ground from solid high speed steel. A range of hole diameters can be drilled using only one tool and holes are deburred automatically by the following step.
*Suitable for drilling in alloyed and non alloyed steel sheet, pipes and profiles upto 900N/mm2 and upto a wall thickness of 5mm. Also suitable for wood and plastics.
