Bosch GDB 350 WE Professional Diamond Core Drill 3200 Watt 350 millimeter Black/Blue/White

The Bosch GDB 350 WE Professional Diamond Core Drill is a dedicated corded electric machine built for structural concrete work. It draws 3,200 W from the mains to bore through standard and reinforced building materials. Site engineers use this core drill mainly for large-diameter penetrations needed for plumbing, ductwork, and electrical installations. The tool must be mounted on a compatible drill stand to stay stable during heavy-duty use. A continuous wet-drilling process cools the cutting head while flushing out debris. The machine is strictly rotary: it relies entirely on diamond core extraction and has no hammer action.

Built for demanding construction environments, the drill holds its output over extended work periods. Operators select the right rotation rate for the hole size using the adjustable speed control. Power is supplied through a direct AC mains connection to prevent interruptions during deep coring. The external housing comes in Bosch's familiar black, blue, and white colour scheme. When set up correctly, the equipment handles high-torque applications without stalling in dense mineral structures. Maintenance follows standard care for electrical construction equipment that is regularly exposed to water.

• Maximum concrete drilling diameter of 350 mm accommodates large pipes and ventilation ducts.
• 1¼" UNC spindle mounting ensures direct compatibility with standard professional core bits.
• 3-speed mechanical gearbox allows operators to match the cutting rate to the core size.
• 1,250 RPM maximum rated speed maintains steady cutting progress through heavy reinforcement.
• 11.9 kg overall weight provides the necessary physical mass for stable stand-mounted drilling.
