Step Drill Bits

DART's step drill bits have the ability to drill metal up to 1/4 inch thick. Featuring HSS ground with straight flutes, they possess a split point for spot drilling without pre-drilling. Step drill bits are a type of drill bit with multiple steps, allowing them to drill holes of different diameters without switching out drill bits.

The step drills in our range are suitable for sheet metal, stainless steel, steel, metal/mild steel, cast iron, aluminium, non-ferrous metals and plastic. Browse the DART range in full below which includes straight flutes, spiral flutes and step drill bit sets.
