Irwin Diamond Tile Drill Bit – 10507897

The IRW10507897 is a 12mm diameter diamond tile drill bit, offering the largest capacity in the range for substantial penetrations and heavy-duty applications. This diameter is ideal for creating holes for larger pipework, cable bundles, substantial fixings, and mounting hardware in ceramic, porcelain, and other tile materials across commercial and residential projects. Engineered with tough brazed diamond grit, this 12mm bit provides fast, smooth cutting performance through all grades of hard and soft tiles. The raised diamond grit edge makes starting in hard tile effortless without requiring a guide, whilst the reverse spiral design forces water towards the cutting head, keeping the diamonds cool to maximise cutting speed and extend tool life significantly. The auto slug ejection slot facilitates continuous, uninterrupted cutting, enabling professional tilers and contractors to work efficiently on demanding installations. For the best results and longest possible lifespan, always use with water during drilling operations to enhance cooling and performance.
