The Drilax 3-3/4 Inch Chrome Series Diamond Hole Saw cuts clean, round 3-3/4 inch openings in porcelain, ceramic, tile, glass, granite, quartz and marble. A triple layer of electroplated diamond on a solid steel body grinds through hard, brittle materials instead of cracking them, so you get a smooth hole without an angle grinder. It has a 1-1/8 inch depth of cut and a standard 3/8 inch shank that fits the drill you already own. It is sized for common shower valve access holes and drain holes.

Benefits

Triple-Layer Diamond Coating: Electroplated diamond grit on a notched rim grinds clean, chip-free holes in tile, stone and glass.

Solid Steel Body: Spins true with less wobble, even on a hand drill, and holds up to repeated large cuts.

1-1/8" Depth of Cut: Clears full tile and backer board, and thick countertops.

3/8" Standard Shank: Fits standard corded and cordless drills and drill presses, no adapter needed.

Key Features

  • Triple-Layer Diamond Coating: Electroplated diamond grit on a notched rim for fast, clean, chip-free cutting.
  • Solid Steel Body: Spins true, cools better and holds up to repeated use. Chrome nickel finish.
  • Side Cooling Slots: Improve water flow and debris removal, and make it easier to remove the core.
  • 3/8 Inch Standard Shank: Fits most cordless and corded drills with no special tools.

Compatible Materials

  • Materials: Porcelain, ceramic, tile, glass, granite, quartz, marble and natural stone.
  • Tool Compatibility: Standard corded and cordless drills and drill presses.
  • Not For: Concrete, brick, metal or wood. Do not use hammer mode or run it dry.

How To Use

  • Mark & Wet: Mark the hole and add water, or spray or drip water on the spot. A ring of plumber's putty makes a small water dam.
  • Start at an Angle: Hold the drill at a slight angle and drill slowly to cut a C-shaped groove. A scrap-wood template with a matching hole also keeps the bit from wandering.
  • Bring to Vertical: Slowly bring the drill upright and keep the cut wet.
  • Light Pressure: Use low speed and let the diamonds do the work. Dip the bit in water every 20–30 seconds.

Use Cases

  • Shower Valves: Valve access holes in wall tile.
  • Drains: Drain holes in tile floors.
  • Bathroom Remodels: Plumbing access holes in porcelain and ceramic.
  • Stone & Glass: Clean holes in marble, quartz and glass.

F.A.Q.

Q: What materials can it drill?
A: Porcelain, ceramic tile, glass, 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. Running it dry wears the diamond coating quickly.
Q: How do I start without a pilot bit?
A: Start at a slight 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 tile, glass and occasional stone work. Vacuum brazed bits have a tougher diamond layer for heavy use on granite and quartz.
