1800W High-Torque Electric Motor: Provides sustained rotational power to drive diamond core bits through hard cured concrete, stone, and structural brick without thermal bogging.
Optimized 1200 r/min Rotational Speed: Engineered to achieve fast material penetration and smooth cylindrical hole cutting for core barrels up to 130mm in diameter.
Integrated Continuous Water Cooling System: Features a dedicated fluid inlet that feeds water into the cutting zone to flush abrasive slurry, preserve diamond segments, and eliminate airborne silica dust.
Solid 130mm Coring Capacity: Built for drilling accurate service penetrations for sanitary pipes, drainage lines, electrical conduits, and exhaust flues.
Portable 11.6 kg Job-Site Architecture: Provides rigid, vibration-damping column stability while remaining manageable for transport and vertical mounting across construction sites in Nepal.
