With the Makita D-40135 step drill bit, you can effortlessly drill multiple hole sizes from 4 to 32 mm without constantly switching bits. Featuring 15 steps, it delivers clean, burr-free holes in sheet steel, aluminium, non-ferrous metals, cast iron, and plastic without deforming thin materials. The durable TiN coating minimizes friction and heat buildup, extending the cutting edge lifespan during intensive tasks. Ideal for creating cable entries in electrical enclosures or pipe penetrations in thin-walled metal, its 10 mm straight shank with three flats prevents slipping in the chuck to ensure accurate, controlled drilling.
