Drill up to 14 different sizes with one Milwaukee step drill bit. Increasing in 2-3mm intervals from 6-35mm, it’s a great option for enlarging existing holes and a far more durable alternative to twist drill bits – the thicker core offers a much higher resistance to breakages.
Milwaukee step drills can be drilled into a variety of materials including ferrous and non-ferrous sheet metals, profiles and pipes, as well as copper, brass, aluminium, stainless steel and plastic. Suitable for material thicknesses of up to 4mm, with the use of coolant recommended for longer bit life.

• 2-3mm step intervals – choice of 14 steps from 6-35mm
• Laser-engraved size markings – easy to identify
• 10mm shank diameter – overall length of 90mm
• More durable than twist drills – thick core resists breakage
• Suitable for metals and plastics – 4mm maximum thickness
• Optimised for cordless – ideal for high-speed cordless drills
• Rapid Strike tip – precise centering and jam-free performance
• Longer life – custom steel and black oxide coating
