About this product
A 12mm diamond drill bit for making clean, fast holes in porcelain and ceramic tiles. This size suits larger tap holes, concealed shower valves and medium-sized pipe penetrations in bathroom installations.
The bit uses premium-grade, braze-bonded diamonds set using vacuum brazing technology, helping the diamonds stay bonded for a long working life. It offers easy starting with no drill guide required, and needs only minimal water cooling rather than a continuous water feed.
Core waste material auto-ejects, allowing continuous hole cutting without interruption. A Tri-Flat shank provides good grip and performance when used with cordless drills.
