Features & Specification

Festool KHC-S 18-Basic Cordless Rotary Hammer Drill

Compact 18V combi-hammer with SDS-Plus tool holder, chiselling function and 1.7 joules of impact energy.

18V • 1.7J Impact Energy • SDS-Plus

The Festool KHC-S 18-Basic cordless rotary hammer drill combines compact handling with powerful performance for professional assembly, drilling and light chiselling tasks. Its lightweight design makes it easy to control, while the pneumatic hammer mechanism and robust brushless EC-TEC motor deliver 1.7 joules of impact energy for fast progress in concrete, stone and masonry.

The KHC-S 18 supports hammer drilling, chiselling and conventional drilling without impact, making it a versatile choice for a wide range of installation and interior fitting work. A depth stop enables accurate drilling depth adjustment, while the integrated LED provides improved visibility in darker working areas.

Safety features include electronic KickbackStop, which helps reduce the risk of injury if the drill suddenly jams, and a safety lock to help prevent unintended startup. For cleaner working, the tool can also be paired with Festool dust extraction accessories and a compatible mobile dust extractor, with Bluetooth battery functionality enabling automatic extractor activation when the tool starts.
