Drill DeWALT DCH481N-XJ 540 RPM SDS Max 5.4 kg
The DeWALT DCH481N-XJ 540 RPM SDS Max 5.4 kg is a heavy-duty rotary hammer designed for professional concrete and masonry work. It features a brushless motor and an SDS Max chuck, delivering reliable impact performance with a maximum idle speed of 540 RPM and an impact rate of 3150 bpm. Weighing 5.4 kg, the tool is intended for drilling anchor and fixing holes up to 40 mm in concrete, brick and other masonry materials. The design combines compact dimensions and ergonomic handling with safety features to suit demanding jobsite conditions.
The brushless motor improves runtime and reduces maintenance compared with brushed alternatives while providing consistent torque under load. The anti-rotation system enhances user safety by detecting loss of control and instantly cutting power. Low vibration levels (9.4 m/s²) reduce operator fatigue during prolonged use. Additional features include a bright white LED with a delay function for improved visibility in low-light environments, selectable rotation stop for chiselling, and an impact stop mode for rotary-only drilling with dry diamond cores.
Select an appropriate SDS Max drill bit or chisel for the intended task and secure it in the chuck according to the manufacturer's instructions. Use the rotation stop mode for chiselling operations and the impact stop mode when performing rotary-only drilling with dry diamond cores. Start drilling at low speed to establish the hole and then apply steady pressure while allowing the tool to do the work; avoid excessive side load on the bit. Always ensure the battery system is correctly fitted and charged, and inspect the bit and tool before use. Maintain stable stance and hold the tool with both hands for control, and allow the tool to cool periodically during extended continuous operation.
Wear appropriate personal protective equipment including eye protection, hearing protection and dust control measures when drilling into concrete or masonry. Use suitable dust extraction or local ventilation when performing dry drilling with diamond core bits. For prolonged drilling tasks, use the tool in planned intervals to prevent overheating and to preserve battery life and motor performance.
