3500W High-Output Motor: Delivers substantial continuous torque at 700 RPM to smoothly rotate large-diameter diamond core bits through cured concrete and steel rebar.
Integrated Continuous Water Source System: Feeds pressurized water directly into the cutting zone to flush abrasive slurry, cool diamond segments, and eliminate harmful airborne dust.
Large 200mm Maximum Coring Diameter: Slices clean cylindrical openings up to 200mm (8 inches) for heavy MEP pipes, drainage lines, electrical risers, and ventilation ducts.
Rigid Steel Stand & Semi-Automatic Feed: Heavy-duty column provides chatter-free vertical tracking, reducing operator fatigue and protecting core barrels from binding.
Solid 25 kg Stable Workstation: Heavyweight steel and cast construction anchors securely to floors or walls, delivering true axial stability on active construction sites across Nepal.
