The 1‑1/4 inch diamond drill bit includes a removable pilot drill bit, allowing you to create a stable locator ring before continuing the cut. This ensures accurate starts on smooth tile and stone surfaces, especially important for countertop and backsplash installations.
A triple‑layer diamond coating provides enhanced cutting speed and durability, delivering clean, chip‑free holes through quartz, granite, porcelain, ceramics, and tile. This coating ensures long life and consistent performance even in dense materials.
The solid steel body spins true and cools efficiently, reducing vibration and improving precision. With a 1‑3/8 inch cutting depth, it handles thicker stone and tile with ease while maintaining dust‑free, smooth cutting.
A standard 3/8 inch shank makes it compatible with common household drills. For glass drilling, this bit is used without the pilot drill to prevent cracking and ensure a clean entry.
Compatible Materials

How To Use
How To Use
- Mark & Secure: Mark your center point on the tile. Use the included pilot drill bit to create a shallow 1/8-inch guide ring.
- 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.
- 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.
- 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.

F.A.Q.
F.A.Q.
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.
