Blue aluminium pistol-grip air drill with keyless chuck and trigger throttle

Chicago Pneumatic

Chicago Pneumatic CP1117P09 air drill 1/4 in NPT keyless

SKU CH-7JY6-495KA

Air-powered drill delivers 900 RPM free speed with 3.57 to 14.30 ft-lb torque and keyless chuck

  • Variable speed trigger gives precise drilling control
  • 900 rpm free speed delivers fast hole making
  • Planetary gear train provides 3.57 to 14.30 ft-lb torque range
  • Aluminum housing keeps weight down to 3.4 lb
  • Ball bearing construction ensures smooth long life

Purpose and User

This Chicago Pneumatic air drill suits mechanics and technicians who need a lightweight pistol-grip tool for repetitive drilling tasks. Its 3.4 lb aluminum housing reduces fatigue during extended use, while the variable-speed trigger allows precise control from start to finish.

Air Consumption Match

The drill demands 29.8 CFM at full load and requires a 90 psi supply through a minimum 3/8 in hose. If the compressor cannot sustain that flow, the tool will stall or run below its rated 900 RPM free speed, so verify shop air capacity before purchase.

Sustained Load Behaviour

Under continuous operation the planetary gear train and ball bearings maintain consistent torque between 3.57 and 14.30 ft-lb without the speed drop-off common in short-burst testing. Average consumption settles at 7.40 CFM over a 15 second run, reflecting real-world duty cycles rather than peak spikes.

Questions about this item

What does the 900 RPM free speed mean when the drill is under load?

The 900 RPM is the no-load speed; actual drilling speed drops based on material resistance and available air pressure.

How does the 1/4 in NPT inlet limit airflow in a workshop setup?

The 1/4 in NPT fitting requires a minimum 3/8 in hose to deliver the 29.8 CFM full-load demand without excessive pressure drop.

What clearance does the 8 in overall length need for tight spaces?

The 8 in pistol-grip body needs roughly that much straight clearance plus room for the hose connection at the base.
