Irwin Diamond Tile Drill Bit

The IRW10507892 is a 5mm diameter diamond tile drill bit, perfect for creating smaller pilot holes and drilling precise openings in tiles for fixings and fittings. This compact size is ideal for detailed tiling work where accuracy is paramount, such as drilling holes for wall plugs, pipe penetrations, or mounting brackets in bathrooms and kitchens. The 5mm bit features tough brazed diamond grit that cuts smoothly through all grades of hard and soft tiles, whilst the raised diamond grit edge allows you to start drilling in hard tile without needing a guide. The reverse spiral design forces water towards the cutting head, keeping the diamonds cool to increase cutting speed and extend tool life. The auto slug ejection slot enables continuous, uninterrupted cutting, making this bit highly productive for professional tilers and contractors. For optimal performance and maximum lifespan, use with water during drilling operations.
