How To Use
How To Use
- Submerge or Spray: Always use water as a coolant. Submerge the material in a shallow tray of water or use a steady drip.
- The Angle Start: Start the drill at a 45-degree angle to create a small "notch" so the bit doesn't "walk" across the surface.
- Level Up: Slowly bring the drill to a 90-degree vertical position once the hole is started.
- Light Touch: Use very light pressure and low RPM. Let the diamonds grind the hole; do not force the bit.
Expert Tip: Frequent "pulsing" (lifting the bit up and down slightly) allows fresh water to enter the hole and flush out debris, extending the life of the bit.

Q: What materials can I drill with these?A: They are perfect for sea glass, beach stones, sea shells, gemstones, ceramic, porcelain, and small glass bottles.
Q: Do I really need to use water?
