"When used with the Erbauer drill guide (also available at Screwfix) this diamond drill produces very good results. Needed holes cutting in ceramic tiles in the bathroom to provide clearance for 15mm copper pipe coming back through stud walls and this item did a brilliant job. Good clean holes (used cordless combi drill), no wandering (because of the guide) and most importantly no broken tiles so NO WASTAGE. No signs of wear, but then I have only cut 8 holes with it and only in Ceramic so can't comment (yet) on the performance on Porcelain tiles."

Review 3 for Erbauer Diamond Tile Drill Bit 16.5 x 8mm
"Fine if you're cutting ceramic but don't bother if it's porcelain. Cut two holes and gave up on the third. Totally blunt. If you have anything more serious to do, invest in a better bit......or buy ceramic tiles!"
