• Mark & Wet: Mark the hole and add a puddle of water, or spray or drip water on the spot.

Q: What materials can it drill?
A: Glass, porcelain, ceramic tile, granite, quartz, marble and natural stone. It is not designed for concrete, brick, metal or wood.
Q: Do I need water?
A: Yes. This is a wet-use bit. Keep the cut wet to cool the diamonds, control dust and get a clean, chip-free hole.
Q: How do I start without a pilot bit?
A: Start at about a 45 degree angle to cut a small groove, then bring the drill upright. A scrap-wood template with a matching hole also works.
Q: Will it fit my drill?
A: Yes. The 3/8 inch standard shank fits most corded and cordless drills and drill presses.
Q: What is the difference between Chrome and Vacuum Brazed hole saws?
A: Chrome Series bits have an electroplated diamond coating and are a great value for glass, tile and occasional stone work. Vacuum brazed bits have a thicker diamond layer for heavy use on granite and quartz.
