Product Information

Product Overview

This 3/16"-1 3/8" diamond countersink bit enlarges and bevels holes in tile and stone after you have drilled a pilot. The diamond-coated cone grinds the opening wider and cleans up the edge, so pipes, fittings, and fixtures seat flush without cracking the tile. It is the finishing step for anyone drilling penetrations in porcelain, ceramic, glass, or natural stone.

The tapered profile works a range from 3/16" up to 1 3/8", so one bit covers everything from small supply lines to larger fixture holes. Run it wet to keep the diamond cool and the dust down, and ease into the cut rather than forcing it.

Cracked tile around a hole is a callback nobody wants. Tile Outlets stocks this diamond countersink for clean, chip-free openings.
