The YT-81980 Diamond Drill Rig delivers 2200 W of power with a maximum drilling diameter of 180 mm and a speed of up to 1200 rpm, making it ideal for heavy-duty applications such as drilling sewer pipe passages, ventilation ducts, and electrical installations.
Its wide drilling range (30–180 mm) makes it suitable for common pipe diameters (110 mm and 125 mm). The drill can be used handheld or stationary with the included stand, offering flexibility for different job site conditions.
The centrifugal mechanical clutch (5 springs) ensures smooth drilling through reinforcement bars, while the water cooling system increases efficiency, safety, and drill bit longevity. Built from corrosion-resistant materials, the rig guarantees long-term reliability.
Safety and comfort are enhanced by low vibration levels (2.90 ± 1.5 m/s²), no impact operation (eliminating destructive vibrations), and a stand with gearbox that reduces operator effort when drilling hard materials.
The YT-81980 comes equipped with:
- Drilling rig body
- Stand / tripod with gearbox
- Rear bracket
- Additional handle with clamp
- Compatible with:
- Diamond core bits YT-60371 to YT-60379 (32–182 mm)
