Choose the Correct Fit
Confirm that the required finished diameter is among the #4 bit’s marked sizes.
Use a cordless drill at low speed for stainless steel or high speed for mild steel, as Milwaukee recommends.
Installation & Care
Seat the shank securely in the drill chuck. Start square and stop advancing once the chosen step reaches the required depth.
Allow the cutter to cool before handling it. Clear chips safely and inspect the cutting edges before the next hole.

Important Product Questions
Which hole sizes does this bit provide?
It has 12 steps covering 3/16–7/8 in. Use the etched size marks to select the required diameter.
What speed should I use?
Milwaukee recommends low speed for stainless steel and high speed for mild steel. The cobalt bit is recommended for material up to 14 gauge.
How do I avoid making the hole too large?
Watch the laser size references and stop feeding when the chosen step finishes the hole. The next step enlarges the diameter if advanced into the work.
