SDS-MAX rotary hammer 2x18V LXT aws/aft DHR400ZKUN

Heavy-duty tasks without cables and compromises

Working with concrete, stone, or brick in difficult conditions requires a tool that not only generates sufficient force but also allows for freedom of maneuver. This model combines 36V power (achieved by connecting two 18V LXT batteries) with a brushless DC motor, resulting in impact energy of 8,0 J. This value allows for fast drilling of holes up to 40 mm in diameter in concrete and efficient chiseling. This allows installers to avoid constantly plugging in extension cords, while end users gain the mobility necessary for renovation work in hard-to-reach places.

Working comfort and operator safety

Hammers of this type are naturally heavy and generate large vibrations, which during prolonged work can lead to hand fatigue. Here, AVT (Anti-Vibration Technology) is key, reducing vibration levels to 5,0 m/s². This is not only comfort for the operator but real protection against carpal tunnel syndrome. Additionally, built-in Active Feedback sensors automatically shut off the tool in the event of sudden kickback, which is a vital safety element when using large drill bits or chisels. The tool also features an electronic speed control system and soft start, which prevents sudden current surges during startup and facilitates precise control over the drilling process.

Application and resistance to external conditions

The device offers two operating modes: hammer drilling and pure chiseling, making it a versatile tool for installing anchors, punching installation holes, or removing plaster. The SDS-Max type chuck ensures a rigid grip for the heaviest drill bits and chisels. It is worth noting the XPT technology, which increases resistance to dust and moisture – essential when working in construction dust or outdoor conditions. The tool is also compatible with the AWS (Auto-start Wireless System), allowing for the automatic activation of construction vacuums upon starting to drill, which significantly improves air quality on the construction site.

The set includes a durable plastic carrying case and essential accessories: side grips (auxiliary rod and D-handle) for better control, a depth gauge, and grease for the maintenance of drill bits and chisels. Please note that this version is supplied without batteries and a charger – it requires two LXT series batteries with a capacity of 3 Ah or higher for optimal performance. This allows you to easily adapt the set to your own Makita machine fleet. The tool weighs approximately 7.3 kg without batteries, and its dimensions are 473 x 120 x 285 mm, ensuring good ergonomics despite the high impact power.
