Fast drilling with Milwaukee
- Superior resistance to heat: Engineered with cobalt steel and an AlCrN coating, it lets you drill through stainless steel without overheating.
- Accurate starts without walking: The specialized tip geometry engages immediately on metal surfaces so you avoid pre-drilling and unwanted slipping.
- Secure non-slip chuck grip: Featuring a 3-flat shank design, this accessory prevents slippage inside the tool chuck during heavy drilling tasks.
With the Milwaukee 48899372 step drill bit, you can drill and deburr clean holes from 4 to 20 mm in sheet metal, control panels, and tough stainless steel. You eliminate the hassle of swapping standard bits, smoothly stepping through 10 hole sizes with one tool. Built from cobalt steel with a heat-resistant AlCrN coating, it reduces friction and delivers up to 10x longer tool life in challenging metals. The dedicated centering tip starts immediately on contact without walking or pre-drilling on slick surfaces. Fitted with an 8 mm 3-flat shank, this bit stays firmly locked in your chuck for maximum torque transfer and complete drilling control.
