The Milwaukee Step Drill Bit (#9) is built for professional electricians and contractors who need clean, precise holes in metal and plastic on the job site. Featuring a single cutting edge design for superior control and a cleaner finish, this high speed steel bit handles panel knockouts, electrical boxes, and conduit entry points with ease. The speed start tip eliminates bit walking for faster penetration, while the black oxide coating resists corrosion and works seamlessly with drilling lubricants. Laser-etched size markings keep you accurate without guesswork — ideal for rough-in work, service upgrades, and any application where time and precision matter.
