Application

  • Heavy Steel & Tough Alloy Drilling: Bores 1/2" holes through thick plate steel, cast iron, and stainless steel at an ultra-low 220 RPM without burning cutting edges.

  • Large-Diameter Thread Tapping & Reaming: Drives heavy machine taps and bridge reamers smoothly with massive low-speed torque and instant reverse control to back out tooling cleanly.

  • Heavy Hole Sawing & Core Cutting: Powers large-diameter hole saws and annular cutters through heavy enclosures and structural pipe without motor stall.

  • Tube Rolling & Mechanical Maintenance: Performs boiler tube expanding, mechanical drive rotation, and high-resistance machinery servicing where maximum torque is critical.

Description

The Zipp Air Tool USA ZRD220 1/2-Inch Industrial Reversible Pneumatic Drill is an ultra-low-speed, maximum-torque drilling machine built for heavy fabrication, structural steel construction, and industrial MRO. Precision-geared to run at an ultra-low 220 RPM free speed, this heavy-duty air drill multiplies motor torque to drive large cutting bits and hole saws up to 1/2" (13 mm) through hardened metals, structural plate, and tough alloys without bogging down.

Constructed with a rugged industrial-grade metal housing, the ZRD220 delivers the leverage and mechanical durability needed to withstand extreme rotational resistance. Measuring 230 mm in length and weighing 3.8 lbs (1.7 kg), its balanced pistol-grip frame allows operators to maintain steady tool alignment and control during demanding cutting cycles. Featuring a 3/8"-24 spindle thread, one-touch forward/reverse selector, and an efficient 5 CFM (141 l/min) air consumption rating at standard shop pressure, the ZRD220 is the premier choice for extreme-duty metalworking and tapping operations.
