Any expert/professional tilers here who can advise what make of porcelain drill bit I can buy that wont blunt after 3 holes drilled into solid porcelain tiles? I used the fancy water drip device and didnt drill dry. First bit was £7 from Homebase so I wasnt surprised when it blunted after one hole. Second one was on offer from £19.95 to £9.95, DeWalt from Screwfix online and I was disappointed that it blunted after 2 holes drilled. Any advice gratefully received as dont want to waste more money. Drill bits cost more than the towel rail and toilet roll holder !
