Makita HR4511C Corded Rotary Hammer SDS-max, 45 mm, 9.4 J

Rotary hammer with SDS-Max chuck and a powerful 1350 W motor, designed for the heaviest drilling and demolition work in concrete, reinforced concrete, and stone. The tool supports two modes: "Hammer drilling" and "Chipping only". Equipped with the AVT active vibration damping system. A safety friction clutch automatically disconnects rotation if the bit jams, protecting the operator and preventing gearbox damage. The constant speed control system automatically increases power under load. Soft start ensures a smooth start without jerks. No-load stroke suppression automatically reduces engine speed and body vibration in idle mode. LED indicators notify about the need to replace carbon brushes and about a malfunction of the power cable or switch. A special anti-vibration rear handle provides a secure grip.
