Rated 5 out of 5 by from Excellent Porcelain Tile Drill I have bought several sizes of these Diamond Tile Drills and all have performed well. After several holes drilled, they are still useable.

Rated 1 out of 5 by from Worn out after 2 holes :( Drilled 2 holes in 8mm porcelain tiles. I took care to use the correct drill speed and not let the drill bit overheat. Even with this careful use the cutting surface was too worn out to dill a third hole. Not fit for purpose. Will obviously return for refund.

Rated 5 out of 5 by from Erbauer Diamond Tile Drill Bit Bought this as I lost the arbour to my tile drill set. I was sceptical at first but once on site it cut through the tiles ease. Its a bit on the pricey side and you have to buy the drill guide as well as there is no pilot drill facility with this type but I was impressed. I have only given it 3 stars for reliability as Ive only used it twice so its hard to say at this point.

Rated 1 out of 5 by from Do not buy Tried to drill 2 holes in a standard tile. The cutting edge disappeared half way through. Expensive with poor quality.

Rated 4 out of 5 by from Shortlived Managed 6 holes in porcelain before this had worn out. Screwfix replaced it but the replacement fared no better. Averaged 10 minutes per hole.

Rated 4 out of 5 by from smooth through tile wall need to get that 15mm central heating pipe through the tiled wall nice and clean without cracking the tiles this is the kit to do it for optimum results use with drill guide sucker pad and a perfect hole every time. I used mine to go right through 12 inch thick wall with an extension bit on the end of it .no cooling water needed . just clean out debris in plug periodically while drilling . well worth the price
