The 4 piece glass/tile drill bit set is excellent for all fine drilling requirements. If you need to drill smaller holes then just make use of theseĀ standard carbide tipped glass bits. Hold the drill to stand perpindicular to the tile or glass or other such similar surfaces. If the drill and glass tile can't be securely clamped in place, begin by drilling a very small pilot hole through the glass to act as a guide. Keep the drill bit and hole lubricated with turpentine or water and operate at a low speed. To reduce the risk of chipping around the exit edges of the cut, drill part way through from one side then complete the cut from the other side.
