48-89-9204 #4 Step Drill Bit, 3/16-7/8 In., 12 Steps

The Milwaukee 48-89-9204 #4 Step Drill Bit is a precision tool designed for drilling clean, accurate holes in metal and plastic materials. This stepped drill bit eliminates the need for multiple traditional bits, allowing you to create holes ranging from 3/16 to 7/8 inches in a single operation. The dual-flute design delivers faster drilling with reduced vibration, making it ideal for use with cordless drills operating at high speed. The black oxide coating resists corrosion, cuts faster, generates less heat, and extends the life of the bit compared to uncoated alternatives.

The laser-engraved reference marks let you stop at any hole size with precision, and the rapid strike tip prevents bit walking for faster, more accurate starts. Whether you're drilling metal or plastic, this step drill bit reduces tool changes and improves overall productivity.
