Discover our range of cordless impact wrenches for anchoring and bolting

Our range of cordless impact wrenches has been expanded to cover all your anchoring and bolting needs. With the addition of the new SIW 9-A22 cordless impact wrench, we can now meet the demands of heavy-duty applications. This high-torque wrench brings increased safety onsite with low vibration of just 7 m/s2 and handy little innovations such as the retaining strap and E-spring, designed to keep your wrench and socket secure. Built for harsh construction site conditions, the SIW 9-A22 has a fully metal gear housing, a double hammer gearbox and a ¾’’ anvil delivering more than enough muscle for heavy-duty bolting and anchoring applications in steel, concrete and wood.

As you'd expect, all our Hilti cordless impact wrench tools come with 2-years no cost coverage and if your tool does break, we’ll repair it within 3 days – giving you complete peace of mind.

Powered with our B22 V Li-ion batteries, our range of cordless impact wrenches bring you precision, power and safety onsite.
