Steps to drill clean and precise holes:

  • 1. Start Drilling the hole at an angle about 45 degrees to the surface, so the drill has the chance to start and will prevent the drill slipping
  • 2. Slowly move the drill bit into a more upright position and wobble the drill bit in the circular motion
  • 3. Do not need to apply much pressure, let the drill bit do the work, you will feel the drill bit break through the back of the glass or tile once the hole is completed
  • 4. Take care when using them as a bit can glaze and burn out if used too fast
