Diamond Drill Bit Hole Saw Set 5pc - Extra Long 3/4, 1, 1-3/16, 1- 3/8, 1-5/8 Inch

Materials:

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

Tool Compatibility:

• Brands: Compatible with DeWalt, Milwaukee, Ryobi, Makita, Bosch, and Black+Decker.
• Fits: Any standard handheld or bench drill with a 3/8-inch or 1/2-inch chuck.

Instructions:

1. The Setup: Place the included high-density poly guide over the target area to secure the bit's position.
2. Lubrication: Apply a steady stream of water or oil to the surface before and during the cut.
3. The Cut: Use a low-speed setting on your drill. Apply light, steady pressure and let the diamonds do the work—do not force the bit.

Expert Tip: Cooling is the secret to longevity. Keeping the bit wet prevents overheating, which can double or triple the life of the diamond coating.

Kitchen & Bath Remodels: Ideal for drilling faucet holes, soap dispenser mounts, and plumbing lines in thick stone slabs.

Professional Tile Installation: Perfect for creating clean penetrations in high-hardness porcelain flooring or shower walls.

Home Maintenance: Easily add drainage holes to large ceramic planters or create custom glass aquarium modifications.

Q: Can I use these with my standard cordless drill?
A: Absolutely. The universal 3/8" shank is designed to fit all major brands, including DeWalt, Milwaukee, Ryobi, and Makita.

Q: What is the purpose of the poly guide?
A: Because diamond bits do not have a center pilot bit, they can "skate" across the surface. The guide locks the bit in place for a perfectly centered hole.

Q: Will these work on a 3cm (1-1/4") granite slab?
A: Yes! These bits are specifically engineered with an extra-long body to handle 3cm thick countertops and tiles that standard bits cannot reach.
