The glass and granite drilling set is ideal for mirror, non-tempered glass, tile, and granite counter top installations. The set includes a strong suction cup guide with locking lever to prevent drifting. The diamond bits perform best when used with a drill press, but will work with handheld drills as well.

This set features six diamond bits that cut through a variety of materials from mirror to porcelain. Each bit fits a specific hole on the guide for centered cuts. The set includes the following popular bit sizes: 3/16, 1/4, 5/16, 3/8, 1/2 and 3/4-inch.

The set features a case for use during transport or storage. The see-through case ensures your diamond bits stay protected, organized and ready for their next use.

Convenient guide jig with mated diamond bits and a no-slip suction cup ensure perfectly centering holes in otherwise difficult to drill materials. All are part of this set that performs a simple job that would be impossible using the myriad of traditional bits one usually has around and makes it a pleasure to use and invaluable to have in your toolbox when you need it
