Available In 110v & 240vMakita GA5040R01 125mm Angle Grinder with AVT Handle The Makita GA5040R series angle grinders include the Makita Anti-Restart function, and have been developed based on the current GA5040 series. The Anti-Restart function prevents accidental startup after machine failure for extra user safety. The GA5040R01 comes with an Anti-Vibration Handle (AVT) - as the anti vibration grip receives movement from the machine through the shaft the vibrations are dissipated with help of a ball joint functioning as the fulcrum. The rubber damper between grip and shaft absorbs the vibration from the ball joint decreasing vibration emission and increasing user comfort. When used in conjunction with the Makita SJS II (Super Joint System) vibration control system, the vibration emissions are reduced by up to 25%. FEATURES Anti-Vibration side grip Anti-Restart function Soft start Double insulation Ergonomically best possible barrel grip, with a perfect circumference size and shape which fits the hand for extra comfortable handling \"Super Joint System II\" provides increased machine durability by absorbing the vibration produced by the wheel grinding or cutting material Tool-less wheel cover is adjustable to any desired position Lock-on switch to reduce user fatigue SPECIFICATION Bore Diameter: 22.23 mm Disc Diameter: 125 mm Max Wheel Thickness: 6 mm Anti Restart Function: Yes  Max Wheel Diameter: 125 mm Input Wattage: 1,100 w No Load Speed: 11000 rpm Net Weight: 2.5 kg NOISE & VIBRATION Noise Sound Pressure: 86 dB(A) Noise Sound Power: 97 dB(A) Noise K Factor: 3 dB(A) Vibration K factor: 1.5 m/sec² Vibration: Sanding: 2.5 m/sec² Vibration: Surface Grinding with Anti-Vibration Side Grip: 6.0 m/sec²
