4-1/4 Inch Diamond Hole Saw – Tile, Porcelain, Glass & Granite (Chrome Series)

• Triple-Layer Diamond Coating: Electroplated diamond grit on a notched rim for fast, clean, chip-free cutting.
• Solid Steel Body: Spins true, cools better and holds up to repeated use. Chrome nickel finish.
• Side Cooling Slots: Improve water flow and debris removal, and make it easier to remove the core.
• 3/8 Inch Standard Shank: Fits most cordless and corded drills with no special tools.

• Materials: Porcelain, ceramic, tile, glass, granite, quartz, marble and natural stone.
• Tool Compatibility: Standard corded and cordless drills and drill presses.
• Not For: Concrete, brick, metal or wood. Do not use hammer mode or run it dry.

• Mark & Wet: Mark the hole and add water, or spray or drip water on the spot. A ring of plumber's putty makes a small water dam.
• Start at an Angle: Hold the drill at a slight angle and drill slowly to cut a C-shaped groove. A scrap-wood template with a matching hole also keeps the bit from wandering.
• Bring to Vertical: Slowly bring the drill upright and keep the cut wet.
• Light Pressure: Use low speed and let the diamonds do the work. Dip the bit in water every 20–30 seconds.

• Drains: Drain holes in tile floors and showers.
• Bath & Kitchen: Shower and faucet upgrades in tile and stone.
• Countertops: Clean holes in granite, quartz and marble.
• Glass: Large holes in glass panels.

• Hole Diameter: 4-1/4 inches
• Depth of Cut: 1-1/8 inches
• Shank: 3/8 inch standard
• Body: Solid steel, chrome nickel finish
• Cutting Surface: Triple-layer electroplated diamond
• Pilot Bit: None (start at an angle or use a guide)
• Use Type: Wet drilling only

Q: What materials can it drill?
A: Porcelain, ceramic tile, glass, granite, quartz, marble and natural stone. It is not designed for concrete, brick, metal or wood.
Q: Do I need water?
A: Yes. This is a wet-use bit. Keep the cut wet to cool the diamonds, control dust and get a clean, chip-free hole. Running it dry wears the diamond coating quickly.
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 scrap-wood template with a matching hole also works.
Q: Will it fit my drill?
A: Yes. The 3/8 inch standard shank fits most corded and cordless drills and drill presses.
Q: What is the difference between Chrome and Vacuum Brazed hole saws?
A: Chrome Series bits have an electroplated diamond coating and are a great value for tile, glass and occasional stone work. Vacuum brazed bits have a tougher diamond layer for heavy use on granite and quartz.
