Makita DHS680RTJ 18v Brushless Circular Saw 165mm inc 2x BL1850B 5.0Ah Batteries, DC18RC Charger and Makpac Type 3 Carry Case The DHS680RTJ is Makita\'s first brushless circular saw, which becomes one of the latest member of Makita\'s impressive line up of 18v Lithium-ion cordless tools. Boasting a brand new brushless motor and some new in-built features, the DHS680 looks set to become one of the most popular cordless circular saws on the market MAKITA DHS680RTJ FEATURES Highly efficient brushless motor, that has several benefits over the non brushed equivalent. Firstly, because their are no brushes within the motor, none of the battery power is wasted on creating the heat and friction that happens when using brushes, so consequently the battery lasts longer (per charge) and the energy created by the battery is far more efficient, allowing your tool to achieve higher capacities, so this saw will be able to cut longer, faster and into tougher materials Another benefit of the brushless motor is that, because there are no moving/touching parts in the motor there is nothing wearing away at anything else and getting damaged. Your motor is actually going to be kept in far better condition than before One more impressive new feature is the \'Automatic Speed Control\' found on this saw. This feature allows the computer chip built into the saw to determine the most efficient cutting speed for the job that you\'re doing! It speeds up or reduces the speed of the saw making sure that it only uses the right amount of energy when required - making sure you get the most out of your saw, blade and battery Another handy new feature is the battery state indicator which uses 3 LED lights to illuminate the amount of battery charge you have left so you\'ll never be caught without power just when you need it Soft start for smooth start-up Tool hanger allows you to hang the saw when not in use Blower function blows sawdust off cutting line Larger base than similar models that gives a more stable operation Electronic current limiter for overload protection Large lock off lever for ultimate safety The twin LED job light ensures full visibility of the work piece The Ergonomic soft grip and overall compact & lightweight design gives the user full control and comfort Guide rail adaptor available separately 196953-0 MAKITA DHS680RTJ SPECIFICATION Blade Diameter: 165 mm Bore Diameter: 20 mm Max Cut @ 0º: 57 mm Max Cut @ 45º: 41 mm Max Cut @ 50º: 37 mm Maximum Output: 680 w No Load Speed: 5,000 rpm Overall Dimensions: 350 mm Net Weight: 3.3 kg DHS680RTJ NOISE & VIBRATION Noise Sound Pressure: 83dB(A) Noise Sound Power: 94dB(A) Noise K Factor: 3dB(A) Vibration K Factor: 1.5m/sec² Vibration: Cutting Wood: 2.5m/sec²
