18V Cordless Impact Wrenches



  • Our Original Brushless Motor Technology

No wearing parts (carbon brushes, commutator, field coil)
Our original compact controller

Long Lifetime, Maintenance-Free

The brushless motor offers a significantly extended product life cycle by eliminating trouble including armature burnout, layer short or commutator wear even in severe work environments. Besides, no carbon brush replacement is required.


More Torque. More Power.

  • The max tightening torque is 305Nm for the 18V WR18DBDL2 and 285Nm for the 14.4V WR14DBDL2.
    The torque is increased by 55Nm (18V) and 50Nm (14.4V) respectively, compared to our conventional models (WR18DBDL, WR14DBDL).

Compact Design for Better Handling

  • The overall length is 145mm, which is 23mm shorter than that of our conventional models

Highly Efficient

Longer Runtime per Charge (Approx.)

When loosening M20 high-tension bolts tightened at 350 Nm.

Tightening Mode Selector for a Variety of Applications

Tightening Mode Settings






Tightening Mode Indicator Lamp



Light load work
Installing pipe supports, scaffolding, etc.

Heavy load work
Assembling steel frames, etc.

Delicate work
Tightening small diameter screws, etc.

The tightening torque depends on the material, size and class of the bolt. Make a test fastening to adjust the mode setting to suit the bolt.

Smooth Socket Changes with a Friction Ring Anvil

  • The friction ring holds a socket on the anvil, making it easier to install a pin and O-ring to securely lock the socket in place.

    Note : It is possible to temporality hold the socket in place with the friction ring, but be sure to insert the pin and attach the O-ring before use. If the power tools is used while the socket is temporarily held in place, the socket may fall off and cause an injury.

Newly Designed Airflow System for Optimal Cooling Efficiency

  • The rear fan efficiently cools down the motor and hammer case for more durability.
  • Cordless impact driver shown for illustration purposes only.

Well-Balanced Weight Distribution for Better Work Efficiency

  • Less user fatigue due to the well-balanced design with the center of gravity positioned at the middle finger of the grip hand.
  • Cordless impact driver shown for illustration purposes only.

Dust and Water Resistant

  • Thanks to the unique design of dust-protective cooling windows and fully plastic coating on some important inner parts, this product conforms to IP56 protection class ratings (dust and water resistance) for electrical equipment as stipulated by the international IEC regulations.

  • The equipment has been designed to withstand the effects of dust and water, but there is no guarantee that it will not malfunction. Do not use or leave the equipment in locations where it is subject to excessive amounts of dust, or in locations where it is submerged in water or subject to rainwater. (Only the main unit conforms to the IP56 protection class ratings when equipped with a battery.)

Smooth Control Electronic Switch

  • allows for finer adjustments in the low speed range. It is also more efficient in transferring energy resulting in longer tool life.

Fast Charging Offered by Our Original Charging Technology

Built-in cooling system of the UC18YSL3 charger reduces charging time by efficiently cooling both the battery and charger at the same time during charging.

* Included batteries vary by country or area.

Other Features of the UC18YSL3 Charger

  • Large charge indicator lamp with 4 color status LED and sound alert once charging is complete
  • USB port (5V 2A)
Capable of charging at low temperature (-10°C and above)
