Bosch GCM 18V-305 GDC BITURBO 18v Cordless Mitre Saw 305mm

The Bosch GCM 18V-305 GDC BITURBO is an 18V cordless mitre saw designed for carpenters, joiners, and construction professionals who need corded-class cutting performance without the cable.

Powered by a brushless motor fully optimised for Bosch's ProCORE18V battery technology, this saw delivers cordless performance equivalent to a 2000W corded machine. It achieves a maximum cutting depth of 120mm with the spacer fitted, making it well suited to compound cutting across a broad range of materials. The variable no-load speed of 2,550–4,000 rpm, combined with Bosch's wide saw blade range, gives tradespeople the flexibility to adapt to different applications and material types.

The GCM 18V-305 GDC features an onboard user interface with Bluetooth connectivity, allowing quick battery status checks and speed selection including ECO mode. A tool-less blade change system, upfront bevel control, and automatic motor brake all contribute to safe, efficient use on site. The space-saving glide arm design keeps the footprint manageable, and the saw is compatible with multiple Bosch GTA stands for fixed workstation setups.

Compatible with all Bosch Professional 18V batteries and chargers, this saw integrates seamlessly into the 18V Professional system. For maximum output, Bosch recommends a ProCORE18V battery of 5.5Ah or above. The saw is also compatible with the AMPShare multi-brand battery alliance, offering additional flexibility for those working across multiple battery platforms.
