1. Fixed the drill machine tightly Make sure the spindle is stable and check the electrical and mechanical parts of the drill core bit are good.
2. Concentricity Ensure the concentricity between the spindle and core bit, otherwise, the drill core bit will be rolled from side to side.
3. Cool water Prepared enough water when drilling. The better performance and speed we want, the more water is needed.
4. Pressure Do not press heavily and heat the tube except that you want to see deformation. Give appropriate pressure when drilling.
FAQ
Diamond Drill Core Bit Blunt?
* Find a used grind wheel to grind the segment end and side surface. * Try to drill some holes on the ordinary brick.
Difficult in Coring?
* Flush the residue in the pipe with water. * Tap the core with a rubber or wooden hammer and make the core vibrate. * Take out the core slowly.
Core Bit Stuck?
* Flush the stone chips and debris with a large amount of water * Through different directions with hand to activate the core bit. Do not give a strong twist or lift. * Ensure the segment is good. Kindly take it out of the hole if it is broken before continuing the drill. * Please find a larger drill core bit to cover if the above solutions failed.
