Tradespeople who rely on efficiency and ease of use can, in future, turn to the new generation of professional cordless angle grinders from Bosch: The GWS 18V-115 and -125 C Professional, as well as the GWS 18V-115, -125 and -150 SC Professional. These are the world’s first angle grinders to have a connectivity function: Thanks to an integrable Bluetooth module and the ”MyTools” function in the Bosch Toolbox app, users can connect the new cordless angle grinders to their smartphone. This enables professionals to personalize their tool, configure it individually, and to call up all of the available tool information, such as the serial number and production date. Users also receive information regarding the status of their tools as well as tips for troubleshooting, for instance if one of their tools shuts down due to overheating, directly on their smartphone. Furthermore, the GWS 18V-115, -125 and -150 SC Professional angle grinders come with a multi-functional user interface for the first time, which means that professionals always have an overview of their tool’s status.

Everything under control thanks to the user interface

On the tool, the user interface informs users about the tool status, the charging status and if the tool is overheating. Furthermore, it offers an easily adjustable three-stage speed preselection. The speed is easily adjusted at the touch of a button to suit the material and accessories in order to achieve optimum work results. The LED light is also helpful as it makes it easier to work in dark areas.

EC motor and high-performance battery for increased power and runtime

The new generation of cordless angle grinders offers up to 35 percent more power and a battery runtime that is up to 100 percent longer than previous 18 volt models, which had a 5.0 Ah battery. The basis for this is its brushless EC motor and the new high-performance GBA 18 V 6.3 Ah EneRacer Professional battery. When combined, they give the tools power that is similar to that of a 1 000 W mains-powered tool. This means that the cordless angle grinders can now also be used for extremely power-intensive applications, such as longer cutting or grinding applications – and, for the first time, the range includes a cordless angle grinder with a 150 millimeter disk for a greater cutting depth.

In the EneRacer battery, improved power connectors and a new manufacturing procedure – laser welding – ensure lower resistance, which means that higher currents can be drawn from the battery pack over a longer time. This results in increased power that can be used while also having the most compact battery size and the lowest weight compared to other high-performance batteries in the 18 volt class. Thanks to the improved CoolPack technology, the GBA 18 V 6.3 Ah EneRacer Professional also offers a 135 percent longer lifetime when compared to a conventional battery pack. Furthermore, if you buy a battery from Bosch, you can use it immediately without having to worry about whether it is compatible: the Flexible Power System from Bosch guarantees compatibility with all existing professional power tools and chargers within a volt class.

Improved ergonomics with increased occupational health and safety

The connectivity angle grinders sit comfortably in the hand thanks to a grip circumference of just 156 millimeters and a weight of 2.8 kilograms, including 6.3 Ah battery, and guarantee low-fatigue work. They also stand out thanks to increased user protection: They are the first angle grinders in the world to have “Drop Control”. If the tool falls, this function immediately switches it off as soon as it hits the floor. The new cordless angle grinders also have “KickBack Control”: If the integrated sensor detects a sudden blockage of the angle grinder – for example, if the disk jams – the integrated sensor immediately switches off the motor. The “Intelligent Brake System” ensures that the disk comes to a complete stop within just two seconds. This equipment is rounded off by soft start, start-up protection and an additional handle with vibration damping.

The angle grinders with connectivity and the high-performance GBA 18 V 6.3 Ah EneRacer Professional battery are available now from specialist retail outlets. They are complemented by the comprehensive range of Bosch accessories with cutting, flap, diamond and grinding disks, brushes and dust guards. All prices are recommended retail prices excluding VAT.
