Description

Milwaukee 48899398 Cobalt Step Drill Bit Set (2 Pieces)

The Milwaukee 48899398 Cobalt Step Drill Bit Set includes 2 step drill bits with advanced aluminium chrome nitride (AlCrN) coating, providing up to 10 times longer life than standard Milwaukee step drills. Designed for use with steel and stainless steel, these bits feature a RAPID STRIKE tip for precise, fast starts without material runout or pre-drilling. The bits have optimised tip and step geometry to minimise jamming and distortion, making them ideal for cordless tools. Ground cutting edges with dual spirals enable smoother and faster cutting, while 3-flat safe handles prevent slipping and ensure maximum torque transfer. Laser-engraved size markings provide long-lasting visibility. The set covers diameters from 4 mm to 35 mm.
