Professional Carbide Drill Bits for Glass, Porcelain & Tile

Designed for today’s extremely hard tile materials, these premium Quad-Tip Carbide Drill Bits deliver fast, accurate drilling in porcelain, ceramic tile, glass, marble, and other brittle materials. The four-edge carbide tip provides improved stability, reduced walking, and longer service life compared to conventional single-tip glass and tile drill bits.

Ideal for installing bathroom accessories, shower doors, shelving, mirrors, anchors, and fixtures, these drill bits produce clean, accurate holes while helping reduce chipping on hard surfaces.

For maximum performance, operate at low drill speeds while applying steady pressure and continuous water cooling to the cutting tip.
