  • Dual-Use Handheld & Vertical Versatility: Operates freehand with an ergonomic shoulder rest for horizontal wall penetrations or mounts onto a vertical column stand for stable, deep floor coring.

  • High-Speed 1920 r/min Core Grinding: Produces rapid rotational speed to accelerate diamond segment cutting through dense cured concrete, stone, and brickwork.

  • Integrated Mechanical Safety Clutch: Protects the operator by automatically uncoupling the gear drivetrain if the core barrel jams or binds on internal steel rebar.

  • No-Water-Seal Protective Design: Features an internal fluid-routing architecture that eliminates traditional wear-prone water seals, preventing electrical shorts and internal bearing contamination.

  • Continuous Water Source Connection: Directs pressurized fluid into the cutting zone to cool diamond cutting segments, flush heavy aggregate slurry, and suppress hazardous silica dust across job sites in Nepal.
