  • Heavy-Duty Thread Tapping & Reaming: Drives large thread taps and alignment reamers with high rotational torque and effortless forward/reverse switching to back out tools cleanly.

  • Hole Sawing & Large-Diameter Boring: Cuts through heavy metal enclosures, piping, and hard woods using hole saws and large step bits without motor stall.

  • Cylinder Honing & Heavy Wire Brushing: Powers engine cylinder hones, heavy cup brushes, and deburring wheels that require steady, low-speed pulling power.

Description

The Zipp Air Tool USA ZRD400 1/2-Inch Industrial Reversible Pneumatic Drill is an ultra-high-torque drilling tool engineered for demanding fabrication shops, heavy equipment maintenance, and structural steel assembly. Geared to operate at a controlled low speed of 410 RPM, this industrial drill maximizes cutting torque, allowing operators to drill large-diameter holes up to 1/2" (13 mm) and tap heavy threads without stalling under severe loads.

Built for rugged industrial duty, the ZRD400 features a durable metal housing with an ergonomic pistol grip that provides positive control during high-torque operations. Measuring 230 mm in overall length and weighing 3.8 lbs (1.7 kg), the tool is balanced to resist torsional twist while reducing operator strain. Equipped with a standard 3/8"-24 spindle thread, an instant forward/reverse lever, and an efficient air consumption rate of 5 CFM (141 l/min), the ZRD400 delivers maximum low-speed power and industrial reliability.
