A cordless 40mm rotary hammer powered by 40Vmax XGT li-Ion battery The Makita HR005GD201 SDS Max hammer contains a variety of features such as Active Feedback Sensing Technology (AFT) which shuts down the tool if the rotation speed suddenly slows down, Auto-Start Wireless System (AWS) which allows you to connect it to compatible dust extractors for efficient dust extraction and an Anti-vibration housing for greater comfort upon use. Alongside all of these, it has a powerful brushless motor and will drill up to 25mm. Features: Auto-Start Wireless System (AWS) connects to compatible dust extractors with Bluetooth. The dust extractor automatically runs while the switch is on. Active Feedback Sensing Technology (AFT) shuts down the tool if the rotation speed suddenly slows down Anti-vibration housing and AVT for reduced operator fatigue Brushless motor Variable speed Electric brake Soft start Constant speed control Torque limiter LED job light The soft no-load function automatically reduces the motor speed during idling to suppress the vibration of the machine body 2-mode operation: Rotation with hammering/Hammering only Comes with: 2 x 2.5Ah 40V batteries DC40RA fast charger ADP10 XGT to LXT charger adaptor Side handle Depth stop Bit grease Cloth Carry case Specification: Voltage: 40V Max in concrete (TCT bit): 40mm Max in concrete (TCT core): 105mm Optimum Drilling Range: 18-25mm Impact energy: 8J Shank: SDS Max Blows per minute: 1450-2900 bpm Noise sound pressure: 91 dB(A) Noise sound power: 102 dB(A) Noise K factor: 3 dB(A) No Load Speed: 250-500 rpm Vibration K factor: 1.5 m/sec² Vibration: Hammer Drilling: 5 m/sec² Vibration: Chiselling: 4 m/sec² Net weight: 7.4 - 8.2kg
