Frequently Asked Questions

What is a Milwaukee step drill bit used for?

A Milwaukee step drill bit is used for drilling clean, burr-free holes in thin materials like sheet metal, plastic, and drywall. Its stepped design lets you drill multiple hole sizes—from 1/4" to 3/4"—with a single bit, ideal for electrical, HVAC, and maintenance work.

What are the specifications of the Milwaukee 48-89-9203 step drill bit?

The Milwaukee 48-89-9203 step drill bit is a high-speed steel (HSS) bit with a black oxide finish, ranging from 1/4" to 3/4". It features a 3-flats shank for secure chuck grip and is not impact rated. The manufacturer part number is 48-89-9203.

How to select the right step drill bit for metal?

To select the right step drill bit for metal, match the bit's size range to your hole requirements—the Milwaukee 48-89-9203 covers 1/4" to 3/4". Use high-speed steel (HSS) for general metal drilling; black oxide coating adds lubricity. Ensure the shank fits your drill chuck and avoid impact driving.
