Industrial In-Line Air Drill

The Dynabrade 53078 is a pneumatic drill built for industrial use with a straight inline body. It delivers a free speed of 3,200 RPM and produces 1.20 ft-lb of torque through a planetary gear train. The 1/4 in keyed chuck secures bits for metalworking and assembly tasks. A rubber handle and lever throttle provide grip and control during extended operation.

Compressor And Hose Requirements

Verify that your air supply can maintain 90 psi at the tool inlet with a minimum 1/4 in hose. The drill consumes an average of 3.10 CFM during a 15 second run time, so compressor capacity must meet this demand. Ensure the 1/4 in NPT inlet fitting matches your existing couplers and that the line includes proper filtration and lubrication. The 0.40 HP rating indicates the power level your system must support.

Integration Into Pneumatic Systems

The composite housing keeps the unit light for handheld manoeuvrability in tight workspaces. Ball bearings and planetary gears reduce vibration and wear during continuous industrial duty cycles. Because the throttle is lever operated without variable speed, the drill suits applications where consistent full-speed drilling is preferred. It frees up electric outlets and eliminates cord management in shops with established compressed air networks.

Questions about this item

What drill bits and air fittings come with the 53078, and what must I supply?

The drill includes a 1/4 in keyed chuck and a 1/4 in NPT air inlet. You must provide the 1/4 in minimum hose, a 90 psi air supply, and any drill bits.

How do I decide whether the 3200 RPM free speed suits my application?

3200 RPM free speed suits light-duty drilling in metal, wood or plastic. For larger holes or harder materials a lower-speed drill will deliver more torque.

What does the 1.20 ft-lb torque rating mean when the drill is running on my compressor?

At 90 psi the drill produces 1.20 ft-lb of torque, enough for 1/4 in holes in mild steel; actual torque drops if supply pressure or hose size falls below spec.
