Diamond Drill Bit Hole Saw Set Drill Guide Included

• Ceramics: All types of ceramic wall and floor tiles.
• Porcelain: High-density Grade 5 porcelain (requires constant water cooling).
• Glass: Standard glass, thick glass blocks, and mirrors (not for tempered glass).
• Natural Stone: Granite, Marble, Slate, Limestone, and Travertine.
• Quartz: Engineered stone and solid surface countertops.
• Pottery: Terra cotta, clay pots, and glazed stoneware.

• Lubrication is Critical: These diamond-coated bits must stay cool. Use the included insert guide to create a water pool, or build a "water dam" around your mark using plumbers putty.
• The Guide Advantage: Place the High-Density Poly Insert Guide over your mark. It keeps the bit from "walking" and secures the water pool for dustless drilling.
• Drilling Technique: Use a standard electric or rechargeable drill (3/8 inch shank). Apply steady, even pressure. Do not use the hammer setting.
• Starting without a Guide: If drilling without a guide, start at a 45-degree angle to create a "C" slot, then slowly move the drill to a vertical position once the groove is established.

• Kitchen Renovations: Drilling holes in 1-1/4 inch granite or quartz countertops for soap dispensers, faucets, or air gaps.
• Bathroom Remodeling: Installing shower door hardware, towel bars, or grab bars through porcelain or ceramic tile.
• Home Decor & DIY: Creating drainage holes in ceramic planters or making custom lamps from glass bottles and jars.
• Plumbing Repairs: Routing pipes through tile floors or backsplashes during vanity installations.
• Aquariums: Precision drilling for bulkheads and overflow drains in glass fish tanks.

• Sizes Included: 3/4", 1", 1-1/4", 1-1/2", and 1-3/4"
• Cutting Depth: 1-3/8 inches (30% deeper than industry standard)
• Shank Size: Up to 3/8 inch (Fits standard drills)
• Coating: Premium Electroplated Diamond
• Compatibility: Ceramic, Porcelain, Glass Slabs, Fish Tanks, Marble, Granite, Slate, Quartz, and Stucco.

Q: Do I need a special drill to use these bits?
A: No. These bits feature a standard 3/8 inch shank that fits most regular household electric or cordless drills. Do not use the "Hammer" setting on your drill.

Q: Why is there no center pilot bit?
A: Center pilot bits often cause ceramic and glass to crack upon impact. Drilax bits use a hollow design to ensure the integrity of the material. Use the included guide to stabilize the bit during the start of the cut.

Q: Can I use these for dry drilling?
A: No. Diamond bits generate significant heat. You must use water as a lubricant to keep the bit cool. This prevents the diamond coating from burning off and extends the life of the tool.

Q: What is the maximum thickness these bits can handle?
A: These bits are specially designed with a 1-3/8 inch depth of cut, which is 30% deeper than industry standards, making them ideal for standard and "extra-thick" countertops.

Q: How many holes can I expect to get out of one bit?
A: This depends heavily on the material hardness and the amount of water/pressure used. With proper water cooling and moderate pressure, these bits are designed for multiple professional-grade applications.
