The Makita BO002CG 40V XGT 125mm Brushless Random Orbit Sander is a lightweight and versatile disc sander with an external battery connection.Unlike other similar style sanders, the BO002G’s battery unit is at the end of an adapter unit that can be clipped to your belt. By doing so, it massively reduces the size and weight of the sander which results in better manoeuvrability and control.From the top of sander to the sanding pad, it is only 96mm in height ensuring that as a compact tool, you are give the freedom to easily move it around your work surface.The sander produces a 5mm eccentric diameter while the speed of the sander won’t lessen, even under load thereby providing consistent performance. Supplied with a pad saver, this prevents clogging of the sander resulting in continuous operation.Thanks to the inclusion of the brushless motor, the BO002G delivers 6000-10,000 rpm no load speed with a 5mm eccentric action. Dust is collected neatly into the supplied dust bag, although an external dust extractor can be connected for efficient extraction.Auto-Start Wireless System (AWS) allows the connection to a compatible dust extractor for automatic start-up and shut down via Bluetooth. This saves time and power – using only what is required.At the heart of this Sander is the brushless motor that allows you to use the tool 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.
