This Drilax 3/8 Inch Diamond Drill Bit 5-Pack gives you 5 identical 3/8 inch bits, so you always have a sharp one ready. Each bit has a triple-layer diamond coating on a solid alloy steel body and grinds clean, round holes in glass, porcelain, ceramic tile, granite, quartz and marble instead of chipping or shattering them. The 3/8 inch size is handy for bottle lamps, aquarium tubing and small fixtures.
Benefits
5-Pack Value: Backups on hand for big jobs, so you never stop mid-project when one bit wears.
Clean, Chip-Free Holes: Diamond grinding edge cuts brittle materials without cracking them.
Triple-Layer Diamond Coating: Longer life with proper wet drilling.
Fits Standard Drills: Works in common corded and cordless drills, no special tools.

- Mark & Wet: Mark the hole and spray or drip water on the spot. A small water dam of putty or a wet sponge works well.
- Start at an Angle: There is no pilot bit. Start at about 45 degrees to cut a small groove, or use a drill guide or scrap-wood template.
- Go Upright: Slowly bring the drill upright and drill slow and steady with light pressure.
- Keep It Wet: Keep adding water until you break through, and clear the core from the bit after each hole. Don't use hammer mode.
