HiKOKI WH18DD W2Z 18V Brushless Impact Driver (Body Only)

On a busy construction site, a carpenter reaches for the HiKOKI WH18DD W2Z to drive long structural screws into dense timber. The brushless motor delivers 140 Nm of torque, sinking fasteners quickly without stalling. Its compact 130 mm body fits between studs and joists, while the IP56 rating shrugs off dust and rain. Three speed modes let the user match power to the task—from delicate cabinet assembly to heavy deck framing. The LED light illuminates dark corners, and the belt hook keeps the tool within easy reach. This body-only unit is ideal for professionals who already own HiKOKI 18V slide batteries and chargers.

Why choose it

The WH18DD W2Z combines high torque with a lightweight, compact design. The brushless motor runs cooler and more efficiently than brushed alternatives, extending tool life and battery runtime. IP56 protection means you can work in challenging environments without worry. The three-mode speed control provides versatility: use low speed for precision, medium for general fastening, and high for maximum power. An electronic brake stops the bit quickly for safer, faster work. The built-in LED light improves visibility in tight or dimly lit areas.

Ideal use cases

• Framing and structural work
• Decking and fencing
• Cabinet and furniture assembly
• Metal-to-metal fastening
• Automotive and mechanical repair
• Electrical and plumbing installations

Good to know

This is a body-only tool; you will need a compatible HiKOKI 18V slide-type Li-ion battery and charger. The 1/4" hex chuck accepts standard impact-rated bits. The belt hook can be mounted on either side for left- or right-handed users. For optimal performance, use HiKOKI batteries with a capacity of 2.5 Ah or higher. The tool is covered by HiKOKI's professional warranty when registered.
