A new performance dimension for woodworking ‒ Bosch is systematically extending the Biturbo series for professionals: The GCM 18V-305 GDC Professional is the first Bosch cordless miter saw with an interactive display and connectivity on the market, making it more convenient to use than previous models. The Biturbo saw is optimized for maximum performance with ProCore18V batteries, thus enabling very power-intensive sawing applications for the first time. Craftsmen in woodworking trades now have access to a performance class which up until now was reserved for corded tools with 2,000 Watts. The GCM 18V-305 GDC Professional is operated most efficiently with the ProCore18V 12.0 Ah battery. As a result, it offers the highest cutting performance in its class, with up to 70 percent more cuts per battery charge, as measured by square spruce timber with 10 x 10 centimeters. This has been confirmed by an independent test institute. With the GCM 18V-305 GDC Professional, Bosch provides a total of five powerful Biturbo saws ‒ ranging from a hand-held circular saw through to a miter saw. The Biturbo saws thus cover all common applications.

Highest convenience on the market

The GCM 18V-305 GDC Professional offers high convenience and precision when cutting wood and aluminum profiles to length, cutting floor, wall and ceiling panels, and adjusting components on the construction site. It is the first Bosch miter saw on the market to be equipped with a User Interface ‒ an interactive display ‒ and connectivity. This allows craftsmen to keep an eye on the tool and battery status at all times. In addition, the “Eco Mode” allows you to make up to 20 percent more cuts per battery charge for light applications such as cutting softwood and wooden strips, or you can adjust the cutting speed to suit your application. The pull mechanism of the saw also contributes to its high convenience: The saw is not guided by a carriage, but by a sliding arm made of robust die-cast aluminum. This arm is mounted on ball bearings and is maintenance-free, making the miter saw particularly smooth-running and precise. The miter saw can also be directly placed on the wall to save space. The maximum cutting width is 400 millimeters, the maximum cutting height is 120 millimeters. All control elements ‒ including the bevel control ‒ are situated on the front of the saw and are clearly visible. A double line laser shows where the saw will cut: the cutting line is exactly in the middle of the two projected laser lines. If the saw blade has to be changed, this task can easily be done without additional tools thanks to a clamp screw. The cordless miter saw also features a motor brake to protect the user.

Bosch competence from A to Z

With the Professional 18 Volt System, Bosch ensures compatibility with new and existing power tools and chargers in this voltage class, offering craftsmen planning and cost certainty. There is a wide range of accessories: “Expert for” and “Standard for” blades with carbide technology, which are optimized for cordless saws, extend the runtime.
