The Hilti ST 1800-A22 is an entirely new cordless screwdriver developed for use in the field of metal construction. Thanks to its high power reserves, this tool makes light work of the toughest screwdriving jobs – even on thick steel beams. Its special ergonomic design concept ensures maximum convenience and speed of use. Good balance, the compact grip form specially developed for this type of work and the pressure bulge above the grip ensure optimum power transmission and a comfortable, relaxed hand position without pressure points. Overtightening when driving screws is prevented by the adjustable torque clutch.
