► Step Drill Bits

Multiple Sizes, One Tough Bit

When you’re working with sheet metal, conduit, or thin materials, swapping bits wastes time – a good step drill keeps you moving. The Industrial Shed range of step drill bits is built for trades that need clean, burr-free holes in varying diameters without changing tools. Designed for speed, accuracy, and long life, these bits take on stainless, mild steel, aluminium, plastics, and more with precision.

From SP Tools step drills for heavy-duty industrial sites, Bordo step bits trusted by metal fabricators for smooth cutting and long service life, to Milwaukee step drills with advanced coatings for longer edge life – every option here is engineered for smooth cutting, reduced grab, and effortless deburring.
