The WORX WU384.2 is a 20V cordless brushless rotary hammer kit and the lightweight member of the WU384 hammer range. Its brushless motor and pressure-balancing drive deliver 1.7 J of impact energy, a 0-5180 bpm hammering rate and 1500 rpm no-load speed, with maximum drilling capacity of 20mm in C30 concrete, 13mm in steel and 20mm in wood, and an optimal drilling range of 6-10mm - ideal for anchor holes, conduit runs and fixings in concrete walls and ceilings. The SDS-plus keyless chuck allows one-handed bit changes, and two working modes (rotary drilling and hammer drilling) plus an electronic pulse mode let you start clean holes in tile without chipping. At just 1.5 kg bare and 274 x 76 x 202 mm, with a decoupled floating handle for dual vibration damping, it stays controllable during long overhead sessions. This kit ships with two 20V 5.0Ah batteries and a 6A fast charger for continuous work out of the box.
A brushless motor and WORX pressure-balancing mechanism keep air pressure steady for consistent output; the manufacturer rates drilling efficiency more than 30% higher than the previous WU380S, with 1.7 J impact energy at up to 5180 bpm.
If the bit jams or hits rebar, the active anti-torque system detects the sudden body rotation and cuts power, while the electronic clutch releases the drive - a double safeguard against wrist injury.
