Milwaukee 48-89-9203 #3 Step Drill Bit 1/4in to 3/4in
9-Step Black Oxide Drill Bit with Rapid Strike Tip for Metal and Plastic
The Milwaukee 48-89-9203 Step Drill Bit is designed for drilling multiple hole sizes in metal and plastic using a single bit. This #3 step drill bit features nine hole sizes in precise 1/16-inch increments, ranging from 1/4-inch to 3/4-inch, making it a versatile choice for professional drilling and hole enlargement applications.
Its dual-flute design provides JAM-FREE performance with greater speed and control, while the Rapid Strike tip is engineered to create fast, accurate starts with less heat generation. The optimized geometry and Black Oxide coating help enhance durability, hole quality, and bit life during demanding drilling applications.
Laser-engraved reference marks allow users to identify hole sizes while drilling, helping improve accuracy when stepping up to the required diameter. The 3-flat Secure-Grip shank provides a solid connection with the drill chuck and helps reduce bit slippage during operation.
Optimized for high-speed use with most professional 18-volt cordless drills featuring lithium-ion battery technology, the Milwaukee 48-89-9203 is suitable for drilling and enlarging holes in steel and plastic. Its compact 3/8-inch shank and nine-step design make it a practical addition to professional tool collections.
