Instructions (for maximum durability):
1. DIP IN WATER before drilling and about every 5 seconds during drilling (more often when going through harder materials). We find dipping in water is more effective at cooling the PorcelainPlus speed bits than spraying.
2. FIRM PRESSURE: Let the bit do the work – Do not apply excessive pressure. Place the drill bit on the specified mark, apply pressure, listen for a slight CRUNCH, and start your drilling process.
3. USE PROPER DRILLING SPEED: Cyclone: 600 rpms and slowed down while breaking through the hole.
The Cyclone can be used in a Handheld or Hammer Drill.
Do not use dull or damaged bit.
Wear ANSI-approved safety goggles and heavy-duty work gloves during use and when handling bit.
