4 Inch Diamond Drill Bit with Pilot - Porcelain & Tile Hole Saw

• Compatible Materials: Ceramic Wall & Floor Tile, Porcelain Tile, Natural Stone (Granite, Marble, Slate), Engineered Stone (Quartz), Glass Tiles.
• Compatible Tools: Standard corded/cordless drills (DeWalt, Milwaukee, Makita, Ryobi, Bosch, etc.), right-angle drills, and drill presses with a standard 3/8 inch or larger chuck.

1. Mark & Secure: Mark your center point on the tile. Use the included pilot drill bit to create a shallow 1/8-inch guide ring.
2. Remove the Pilot: For best results and to prevent binding, remove the pilot bit after creating the guide ring. The diamond hole saw will use this ring to stay on track.
3. Drill at Low Speed: Using a standard drill with a 3/8 inch chuck, apply steady, light pressure. Use a low RPM setting (300-500 RPM) and keep the area lubricated with water for cooling and dust control.
4. Complete the Cut: Continue drilling until you cut through the material. The diamond grit does the work—let the tool's weight provide the pressure for a clean, precise finish.

Q: What materials can this diamond hole saw cut?
A: This bit is engineered for hard, brittle materials including ceramic tile, porcelain tile, marble, quartz, granite, and slate. It is not designed for wood, metal, or plastic.

Q: Is it compatible with my drill?
A: Yes. It features a standard 3/8-inch round shank, making it compatible with most standard corded drills, cordless drills, and drill presses. No special adapter is needed.

Q: Why should I remove the pilot drill bit?
A: The pilot bit's sole purpose is to create a small starter guide ring. Removing it prevents the bit from binding in the material, reduces friction and heat, and allows the diamond core to cut more efficiently for a smoother, faster result.
