About this product
This 7mm diamond-tipped drill bit is designed for drilling clean holes in ceramic, porcelain and other tile types, suiting jobs such as wall fixings, plumbing penetrations and mounting hardware in kitchens and bathrooms. The mid-range diameter makes it a versatile choice for general tiling work carried out by professionals and contractors alike.
The bit features tough brazed diamond grit with a raised edge that allows easy starting on hard tile without needing a guide. Its reverse spiral design directs water towards the cutting head, keeping the diamonds cool to improve cutting speed and extend tool life, while an auto slug ejection slot allows continuous, uninterrupted cutting. Using the bit with water during drilling is recommended to further enhance cooling and prolong its lifespan.
