Precautions for Diamond Core Drilling

  • During operation, ensure the water drill is securely fixed to prevent accidents. When working at heights, implement necessary safety measures. Before operating, check if the machine frame is firmly fixed and the drill bit is properly installed.
  • Ensure there is sufficient water supply during drilling to prevent dry operation.
  • During operation, the ventilation openings of the drilling machine must not be blocked to prevent the motor from overheating and burning out.
  • When drilling into rebar, the current will suddenly increase. At this time, reduce the pressure on the drill bit appropriately, but not too much. If the current is too high, the protection switch will automatically shut off; if the current is too low, the drilling speed will slow down, increasing wear on the drill bit. When the concrete quality is poor, causing sand particles or a stuck drill, stop drilling immediately and do not force it. When encountering wooden blocks or asphalt felt, the current will also increase, but no strong vibration will occur, so you can proceed at normal speed.
  • When drilling into the floor, drill slowly to prevent the drill bit from getting stuck due to sudden downward pressure.
  • If the core gets stuck in the drill bit, remove the drill bit and flush the inner cavity with tap water, then carefully extract the core.
  • The core drill can only be used in rotary mode, not in hammering mode.
  • Adopt good safety measures before utilizing the diamond core drill bits.

An 1 1/4” to SDS or SDS plus is needed to run this bit and a constant flow of water is needed. A gallon jug of water with small holes flows plenty of water if you don’t have a hose hook up. I can’t vouch for the long term use of this bit yet but it worked great the first few holes.
