Continuous-rim diamond-grit hole saw for clean, chip-free cuts in hard, brittle materials - porcelain tile, ceramic tile, granite, marble, slate, and glass. The 1" bonded diamond edge stays sharper longer than carbide grit and removes material faster, with an integrated wax lubricant strip that cuts friction and heat to extend cutting life.

• Cutting diameter: 1"
• Continuous-rim diamond-grit edge for smooth, chip-free cuts
• Integrated wax lubricant reduces friction and heat build-up while cutting
• No pilot bit required - start the cut at a 45-degree angle or use a drilling jig
• Cuts porcelain tile, ceramic tile, granite, marble, slate, and glass
• Compatible with the Diablo Snap-Lock Plus mandrel system for quick cup changes
• Designed for use with a handheld drill (corded or cordless)

Tip: Faucet bodies, basket strainers, and small recessed fixtures. Run the drill at moderate speed (around 500-1000 RPM depending on material), keep light pressure, and drip water or run a wet sponge on the cut to flush dust and cool the diamond grit - it extends saw life and prevents glaze-over on glass and porcelain.
