The fitted case keeps all 10 bits grouped Two-bit workflow for tile-mounted projects
This 10-piece set combines eight vacuum-brazed diamond core bits with two carbide-tipped 1/4-inch hex starter bits. The starter bits help establish a shallow reference point before the hollow core bit begins its circular opening, giving the user a clearer starting position on smooth ceramic or porcelain surfaces.

Five core sizes for common fixture openings
The round-shank diamond bits include 3/16 inch x2, 1/4 inch x3, 5/16 inch x1, 3/8 inch x1 and 1/2 inch x1. The repeated 3/16-inch and 1/4-inch sizes support common jobs such as towel bars, floating shelves, mirror brackets, kitchen backsplash accessories and ceramic planter drainage holes. Two carbide-tipped 1/4-inch hex bits are included for shallow starting marks and small mounting holes.

Vacuum-brazed diamond rims with cooling wax
Diamond grit is bonded around the hollow cutting rim for use on ceramic tile, porcelain, granite, marble, stone and non-tempered glass. Cooling wax inside the core softens during rotary drilling and assists with heat management. Pause between holes so the bit can cool, especially when working with dense stone or glass.

Two shank styles
The eight diamond core bits use round shanks for standard three-jaw drill chucks. The two carbide-tipped starter bits use 1/4-inch hex shanks for compatible quick-change holders. Operate in rotary mode only with impact mode off. Begin the diamond rim near 45 degrees, establish a shallow groove, then bring the drill upright while using gentle pressure and small circular movement.

Application boundaries and package contents
Use the set for porcelain and ceramic tile, marble, granite, stone and non-tempered glass. Do not drill tempered glass. Match drill speed and technique to the material and follow the drill manufacturer's operating instructions. The package includes eight diamond core bits, two carbide-tipped tile bits and a fitted storage case.
