The Ralli Wolf RAD402 is a heavier-duty reversible pneumatic drill built for tougher drilling jobs than the standard 3/8" range. Its powerful motor is designed to hold speed under load, so it keeps driving through resistant materials rather than stalling — a must for rugged daily use in fabrication and maintenance shops.

With a 1/2" drilling capacity and a lower 800 RPM free speed, the RAD402 trades top-end speed for higher torque, making it better suited to larger-diameter holes and denser materials than the RAD302. Its reversible function lets operators back out fasteners without switching tools, and the housing is built for rugged, repeated workshop use.

Running off a compressed air supply through a 1/4" air inlet and 3/8" air hose, it draws 8 cfm — more than the RAD302, reflecting its larger capacity. At 1.6kg and 203mm overall length, it's noticeably heavier than the 3/8" model, matching the added torque this size of drill delivers.
