Name: WORX WU391T.3 20V 26mm Brushless Cordless 3-Mode Rotary Hammer Kit with 2 x 5.0Ah Batteries and 6A Charger
Brand: Worx
SKU: WORX-WU391T3
Price: 1680 HKD
Availability: InStock

The WORX WU391T.3 is a 20V cordless brushless 26mm rotary hammer built around an SDS-plus quick-change chuck and a 22mm large-bore hammering cylinder. It delivers 3.0 J of impact energy, 0-950 rpm and 0-4700 bpm, drilling up to 26mm in C30 concrete (optimum range 10-16mm), 13mm in steel and 30mm in wood. A single selector dial switches between rotary drilling, hammer drilling, chiselling and chisel-position adjustment, so one tool covers drilling, breaking and channelling for rebar dowelling, ceiling and interior fit-out, appliance installation and pipework. The bare tool weighs 2.96 kg and measures 344 x 96 x 214 mm; the brushless motor and 20V battery platform keep it cordless for overhead and confined-space work. This kit ships with two 20V 5.0Ah batteries and a 6A charger.

Features & Benefits

3.0 J impact energy with a 22mm cylinder

A 22mm bore cylinder and heavy striker deliver 3.0 J of impact energy at up to 4700 bpm for fast drilling in brick and concrete, with an optimum bit range of 10-16mm and a 26mm maximum.

Four-position mode dial, three working modes

Select rotary drilling (wood, metal, ceramic and driving), hammer drilling (brick and concrete), chiselling (channelling and breaking out) or chisel-position adjustment from one dial - no second tool needed.

Dual vibration damping

Balanced-pressure hammering combined with a suspended, decoupled handle that absorbs high-frequency vibration through elastic elements, reducing transmitted vibration and hand fatigue on long runs.

Electronic and mechanical clutch with anti-kickback

A mechanical clutch and electronic detection act together if the bit jams, and a gyroscopic sensor cuts power when unexpected tool rotation is detected. The trigger also has a centre safety-lock position to prevent accidental starts.

Brushless motor and optimised cooling

The brushless motor needs no brush maintenance and runs more efficiently, while a dedicated air channel through the hammering system plus an under-mounted fan keeps hammer-mechanism temperatures down. A variable-speed trigger matches the speed to the material and bit size.

Dust-extraction port (dust box sold separately)

The nose of the tool carries a mounting interface for the WORX WA1603 PURE FORCE dust extraction module with HEPA filter, sold separately, for cleaner overhead and indoor drilling. The dust box is not included in this kit.

SDS-plus quick-change chuck for tool-free bit and chisel changes
Auxiliary side handle for stable, controlled operation
