EXFEIN Diamond Tile Hole Saw Kit – 12-Piece Set for Tile, Porcelain and Marble

Upgrade your tile projects with the EXFEIN Diamond Tile Hole Saw Kit. This 12-piece ensemble is designed to deliver clean, accurate holes in ceramic tile, porcelain, marble, granite, and other hard surfaces. The set combines six diamond core drill bits in common hole sizes with finger bits, a chamfer bit, a hex adapter, and two dedicated diamond blades for tile work. The result is a versatile, all-in-one solution that supports both professional workflows and DIY renovations.

What’s included

• 6 diamond core drill bits in common sizes: 6, 8, 10, 35, 50, 65 mm
• 1 finger bit, 1 inch size for enlarging holes
• 1 finger bit, 3/8 inch size for fine adjustments
• 1 two-inch diamond chamfer bit for clean hole edges
• 1 hex adapter to connect 5/8 inch-11 thread to a drill
• 2 diamond blades designed for tile work

Surface compatibility and outcomes

Whether you are cutting through glossy porcelain, ceramic tile, or natural stone like marble or granite, these bits are built to handle demanding materials. You can use the tools dry or with water; wet drilling typically yields less debris and can help extend the life of the bits in busy projects.

Construction and durability

Vacuum brazed diamonds are embedded into a robust steel matrix to balance cutting efficiency with longevity. This construction is intended to provide steady performance across multiple jobs, helping you complete installs or repairs with less downtime.

How to use

The set is compatible with a 5/8-inch arbor on angle grinders. If you plan to use a hand drill, attach the included hex adapter and maintain drilling speeds above roughly 2000 RPM. Avoid using impact mode to preserve the diamond teeth and ensure smoother cuts.

Why this kit stands out

• All-in-one solution with core bits, finger bits, chamfer bit, adapter, and blades
• Widely sized core bits accommodate a range of hole diameters for plumbing, fixtures, or outlets
• Specially designed to enable fast chip removal and reduce clogging during deeper holes

In real-world scenarios, you might drill sink or faucet holes, create electrical or plumbing penetrations, or prepare edge openings for fixtures. The kit is suitable for both seasoned professionals and DIY enthusiasts who value precision, efficiency, and a tidy work area. While results can vary by material and technique, this EXFEIN set presents a robust option for tile projects where clean edges and reliable performance matter.
