The Bosch GCU 18V-30 18V Brushless Drywall Cut-Out Tool will provide all day performance from a single battery. The compact machine with slim body delivers both impressive power and the comfort in design to let you keep using it for longer periods of time before fatigue sets in. On a single 4.0Ah ProCORE battery, the Cut-Out Tool is capable of cutting over 100m of 12mm plasterboard with a 3.17mm blade. Due to the dust that gets created when cutting, the power switch is completely sealed to prevent dust from entering the controls. This prevents accidental start ups as well as ensuring that the saw can power down correctly. The cut-out tool includes a soft-start control so that the bit builds up to speed efficiently and doesnt jolt when power is turned on. The GCU 18V-30 is supplied with a vacuum adapter so that your health and working environment remains clear and free from potentially harmful dust. A powerful LED work light lets you light up the working area so that you are able to clearly see what youre doing while a motor brake instantly stops the rotation of the bit when needed At the heart of this tool is the brushless motor that allows you to use it efficiently. As part of the design, the tool utilizes every bit of battery power when you need, all while reducing the need for ongoing maintenance by reducing the amount of heat generated and working more efficiently. The technology in creating a brushless motor system allows for perfect symmetry between battery power and usage ensuring you get all the power you need, when you need it.
