The YT-81983 Diamond Drill Rig delivers 2800 W of real power with a maximum drilling diameter of 300 mm and a speed of 700 rpm, making it ideal for heavy-duty applications such as plumbing, HVAC installations, storm sewer drilling, and restoration works.
Its wet and dry drilling capability allows versatility across different materials, while the tripod stand ensures stability and effortless operation. The planetary gearbox, built with hardened steel gears (53–56 HRC), provides high torque and durability, enabling drilling even in the hardest materials.
Safety features include a residual current circuit breaker with reset button, motor thermal protection, and a reliable overload clutch that engages when excessive resistance is detected, preventing damage to the motor and drill rig. The water cooling system prolongs drill bit life, reduces dust, and improves efficiency, with a lever for easy water supply control.
Weighing 22 kg, the drill can be used both handheld or stationary, and is supplied with a stand, rear bracket, and additional handle with clamp for versatile operation.
