The WORX WU387.9 is the bare-tool version of the WORX 20V professional brushless cordless rotary hammer. It combines a brushless motor with an SDS-Plus quick-change chuck, delivering 2.0 joules of single impact energy, a no-load speed of 0-1450rpm and an impact rate of up to 4700bpm. Three operating modes - rotary drilling, hammer drilling and chiselling - cover concrete drilling up to 22mm, steel up to 13mm and wood up to 28mm, with an optimal bit range of 6-10mm, making it suitable for installation work, plumbing and fire services, air-conditioning, CCTV and signage mounting. A 19.5mm large-bore cylinder and dual anti-oil-leak sealing keep the tool stable through long shifts, and the bare tool weighs just 2.1kg. This SKU is supplied as a bare tool: no battery and no charger are included, making it ideal for users already on the WORX 20V MAX KROSS PACK battery platform.
A brushless motor paired with a 19.5mm large-bore hammering cylinder delivers 2.0 joules per blow and up to 4700bpm, drilling concrete up to 22mm in diameter. The brushless design removes carbon-brush wear for higher transmission efficiency and longer tool life.
The function dial selects rotary drilling, hammer drilling or chiselling, while the SDS-Plus chuck allows tool-free bit changes. Drilling, hammer drilling into concrete and light chipping are all handled by one tool, with an optimal bit range of 6-10mm.
