2-1/2 Inch Diamond Hole Saw with Removable Pilot Bit – Tile, Porcelain, Granite & Quartz

• Removable Center Pilot Bit: Holds position as the cut starts, so the bit does not skate across smooth tile or stone.
• Triple-Layer Diamond Coating: Industrial diamond coating on a solid steel body for fast cutting and long life on hard materials.
• 1-3/8 Inch Depth of Cut: Deeper body for thick tile and countertops.
• Triangular 3/8 Inch Shank: Fits standard drills with no adapter and resists slipping in the chuck.

• Materials: Ceramic, porcelain, tile, granite, quartz, marble and glass. For glass, do not use the pilot bit: it can crack the glass.
• Tool Compatibility: Standard corded and cordless drills and drill presses.
• Not For: Wood, metal, plastic or masonry block.

• Mark & Start: Mark your center point. With the pilot bit installed, drill at low speed until the diamond rim cuts a shallow guide ring about 1/8 inch deep.
• Remove the Pilot: Loosen the set screw with the included hex key and remove the pilot bit. The guide ring now keeps the hole saw on track and prevents binding.
• Drill Wet at Low Speed: Keep the cut wet with a steady stream of water and use a low speed with light, steady pressure.
• Complete the Cut: Let the diamonds do the work until you break through. For glass, do not use the pilot bit, since it can crack the glass. Start the cut on a guide or template instead.

• Plumbing: Pass-throughs for 2 inch pipe in tile walls and floors.
• HVAC: Openings for refrigerant and condensate lines through tile and stone.
• Electrical: Holes for larger conduits and cable bundles.
• Countertops: Large accessory cutouts in granite, quartz and marble.

• Hole Diameter: 2-1/2 inches
• Depth of Cut: 1-3/8 inches
• Shank: 3/8 inch triangular
• Body: Solid steel
• Cutting Surface: Triple-layer diamond coating
• Pilot Bit: Removable center locator bit

Q: What materials can this diamond hole saw cut?
A: Hard, brittle materials including ceramic tile, porcelain tile, marble, quartz and granite, and glass (without the pilot bit, which can crack glass). It is not designed for wood, metal or plastic.
Q: Is it compatible with my drill?
A: Yes. The 3/8 inch triangular shank fits standard corded drills, cordless drills and drill presses with no adapter.
Q: Why should I remove the pilot bit?
A: The pilot only creates the starter guide ring. Removing it prevents binding, reduces heat and lets the diamond rim cut more efficiently.
Q: Do I need water?
A: Yes. Keep the cut wet the whole time to protect the diamond coating and get a clean, chip-free hole.
