21PC HOLE DOZER™ General-Purpose Hole Saw Kit

The Milwaukee 21PC HOLE DOZER™ General-Purpose Hole Saw Kit (49-22-4171) gives you 14 bi-metal hole saws from 3/4" to 5", two arbors and three pilot bits in a customizable hard case. The saws are made in the USA and are covered by a lifetime tooth break warranty.

What it does well

• 3.5 TPI tooth design with more steel behind each tooth for long life in metal.
• Bi-metal construction with 8% cobalt for wear resistance.
• ALL-ACCESS slots and a plug jack make it quick to pop out slugs.
• Thermoset coating cuts friction and drag, so cordless drills cut faster and go further per charge.
• Quick-change pull-back arbor for the large saws and a small thread arbor for the small saws (both 3/8" shank).
• Case with interchangeable pegs, reinforced top and bottom grids and a removable accessory box.

Is this the right kit for you?

It is a general-purpose set: the sizes cover common conduit, pipe, box and fixture holes in metal, wood and plastic. If you mostly cut electrical knockouts, the 19PC HOLE DOZER™ Electricians kit is built around electrical sizes; if you want more sizes, the 28PC general-purpose kit adds them.
