Diamond Drill Bit Hole Saw Set 5pc - Extra Tall 5 Pc Set

Materials:

• Porcelain and Ceramic Tile
• Granite, Quartz, and Marble Countertops
• Stone Slabs and Glass

Tool Compatibility:

• Brands: Compatible with DeWalt, Milwaukee, Ryobi, Makita, Bosch, and Wen.
• Fits: Any standard drill or drill press with a 3/8-inch or 1/2-inch chuck.

1. The Setup: Use the included poly guide to secure the bit's position. If not using a guide, start the drill at a 45-degree angle to create a "C" notch.
2. The Cut: Once the notch is established, slowly bring the drill to a 90-degree angle. Apply light, steady pressure and let the diamonds do the work.
3. Cooling is Key: Always use water to keep the bit cool. A steady stream or spray prevents overheating and can double or triple the life of your tool.

Expert Tip: Never use the hammer setting on your drill. High-speed rotation with a steady water supply provides the cleanest results.

Q: Will these work on 3cm granite slabs?
A: Yes! Because these bits are 30% taller than standard sets, they are specifically designed to handle thick 3cm (approx. 1-1/4") stone countertops with ease.

Q: Can I use these with my cordless drill?
A: Absolutely. The universal 3/8" shank is compatible with all standard cordless and corded hand drills, including brands like DeWalt, Milwaukee, and Ryobi.

Q: Do I need a special lubricant?
A: Standard tap water is the best coolant. Keeping the bit wet significantly improves cutting speed and tool longevity.
