The Bosch GCM 18V-305 GDC BITURBO is a 18V cordless mitre saw with a 305mm blade. Bosch built it for carpenters and joiners who want corded-style cuts without a cable. The brushless motor is tuned for ProCORE18V batteries. Bosch says output matches a 2000W corded saw.
Capacity at 0 degrees is 104 x 341mm. At a 45 degree mitre it cuts 104 x 240mm. With the spacer fitted it reaches 120mm high. The mitre range is 52 degrees left and 60 degrees right. The bevel tilts 47 degrees each way.
Speed runs from 2,550 to 4,000 rpm with an ECO mode. A Bluetooth interface shows battery status. Blade changes need no tools. An automatic motor brake stops the blade fast. The glide arm design saves space. It also mounts on Bosch GTA stands. Bosch advises a 5.5Ah or larger battery.
It suits first fix, second fix and framing work. The saw fits the Bosch 18V Professional system and the AMPShare alliance. Pick it for cordless power and a tidy footprint on site. At 26.8kg it is a solid, steady machine.
