Erbauer Diamond Tile Drill Bit 7mm 2.8 5 5 5
Very good if used right Bought this bit as no other tungsten bit would touch the porcelain floor tiles I put down. Used a normal masonry bit to mark the glaze on the tiles to prevent wandering then switched to this bit and flew through 4 holes with no effort, no dulling or slowing down. If you buy this bit for hard tiles then I recommend marking the holes out and starting them of with a good sharp masonry bit until you reach the diameter of the diamond bit, then switch bits and finish off. USE YOUR DRILL FLAT OUT IN TOP GEAR. Otherwise it can't clear itself, it'll overheat and go blunt. Used like this it will last a fair while. 29 Nov 2014
Works well Item is ok, use dry and leave to cool down as it does get very hot. I drilled 5 holes in very hard Porcelain tiles and it was starting to suffer on the last hole. 27 Nov 2014
Not up to the job Agree with the other reviewer. It started off well for the first 3-4mm but then stopped cutting as if it's blunt. It's described as self cooling and self sharpening but I didn't even get 5mm into the first hole so definitely not worth the money, or time. Gutted. Waste of £14. 17 Nov 2014
Drill bit Used on a slow speed non-hammer drill. Started well but slowed up. Took about half an hour to drill through 4 x thick porcelain tiles, but managed the job where others had failed. 17 Nov 2014
