The Drilax 1-3/8 Inch Vacuum Brazed Diamond Hole Saw drills clean, chip-free 1-3/8 inch holes in porcelain, ceramic, tile, granite, quartz, marble and glass. Industrial diamonds are vacuum brazed in a thick layer onto a solid steel body, so the bit cuts faster and lasts longer than standard electroplated hole saws. The taller body gives a 1-3/8 inch depth of cut, about 30% deeper than standard bits, so it goes through thick countertops and slabs in one pass. 1-3/8 inch is the standard size for kitchen faucet and soap dispenser holes.
Benefits
Vacuum Brazed Diamonds: A thick diamond layer bonded to the rim for faster cutting and up to 5x longer life than electroplated bits.
1-3/8" Depth of Cut: About 30% deeper than standard bits, for 3 cm countertops and thick slabs in a single pass.
Side Cooling Slots: Let water in and debris out, and make it easy to push the core out.
3/8" Triangular Shank: Fits standard corded and cordless drills, and the flat sides keep it from slipping in the chuck.

F.A.Q.
F.A.Q.
Q: What is the difference between vacuum brazed and electroplated hole saws?
A: Vacuum brazed bits have a thicker, stronger diamond layer, so they cut faster and last up to 5x longer than electroplated bits.
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: Do I need water?
A: Yes. Keep the cut wet the whole time to cool the bit, control dust and get a clean, chip-free hole.
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 drill guide or a scrap-wood template with a matching hole also works.
Q: How thick a countertop can it drill?
A: The 1-3/8 inch cutting depth goes through standard 3 cm granite and quartz countertops in one pass.
