We have several series of large drills to meet your construction and industrial needs. The 22 Series works best for general applications up to 22mm holes, while the 33, 44, and 55 Series are better suited for opening and closing large valves, or for drilling larger holes between 1 and 3 inches.
 
Lightweight:
The 22 Series of large drills is strong but lightweight for increased ease of use.
Side Exhaust:
All the Ingersoll Rand large drills come with side exhaust to keep exhaust air pointed away from you and away from your work.
Governed Motor:
No matter which large drill series you’re interested in, you can expect a governed motor that regulates air intake to keep these drills working at the peak of their power curve.
 
33, 44 and 551 Series:
Graduated roll throttle for excellent speed control
Strong, light weight heat-treated aluminum housing for strength without weight
