Chicago Pneumatic CP785 air drill

The Chicago Pneumatic CP785 is a pistol-grip air drill built for general-duty tasks. It uses a 3/8 inch keyed chuck and runs at a free speed of 2,400 RPM. The aluminum housing and handle keep the tool light while standing up to shop conditions. A trigger throttle gives variable speed control for precise starts.

1/4 inch NPT inlet and 3/8 inch hose requirement

The tool connects through a 1/4 inch NPT air inlet and needs a minimum 3/8 inch hose to deliver adequate flow. At 90 psi it draws 4.10 CFM during a 15 second run and 16.5 CFM at full load. A compressor that can sustain this volume keeps the drill operating without pressure drop. The non-reversing design simplifies the air circuit for forward-only drilling.

Sustained torque range of .77 to 3.10 ft-lb

Under continuous load the drill delivers between .77 and 3.10 ft-lb of torque. Ball bearings support the spindle to reduce friction during extended runs. The aluminum body dissipates heat while the trigger throttle lets the operator feather power to match material resistance. This combination helps maintain steady performance through repetitive holes.

Questions about this item

How much air does the CP785 consume when running continuously at full load?

The drill requires 16.5 CFM at full load, so the compressor and hose must supply that volume steadily.

What pressure and hose size are needed for the CP785 to deliver its rated torque?

It is rated at 90 psi with a minimum 3/8 in hose; lower pressure or a smaller hose will reduce the 0.77 to 3.10 ft-lb torque range.

What size air inlet does the CP785 have and what fitting will connect to it?

The tool has a 1/4 in NPT air inlet, so a matching 1/4 in NPT quick-connect or hose barb is required.
