Rated 4 out of 5 by from Good when used wet Had to take the first one back as i used it dry as per the package instructions, and it went blunt after cutting one hole. Other reviews for the smaller sizes mentioned this but not for this size so wasn't aware. Screwfix exchanged it swiftly (thank you to Ringwood branch - always great service) and the exchanged one did 4 holes straight off when kept cool with water. The first was rubbish on second holes and cracked tiles (I assume through the heat) so would recommend this product but use wet. It is pricey but cut through thick ceramic floor tiles in a few minutes per hole. Have scored 1 for reliability as I can't comment after 1 day of use. Why are we asked this just after purchase?

Rated 3 out of 5 by from SO GOOD I BOUGHT IT TWICE This is a great bit if you accept it will only drill a limited number of holes before you need a replacement. Bought the first one last year to fit 12 x 30mm LED lights in the bathroom tiles at home. Tried the same thing this year while fitting tiles in another bathroom with the same bit, but started breaking every tile after 4 successful cuts. Examined the bit and noticed that it was wore down/ glazed on one side. Bought a replacement and it cut 6 tiles in a row without breaking any. I used a block of wood with a 30mm diameter hole cut out as a guide, clamped (not too tightly!) on to a workmate tool bench. A great cutter, but, in my experience, don't expect any more than 20 holes per bit.

Rated 4 out of 5 by from Good drill Bought this today to drill pipework holes in porcelain tiles, they cut well as nothing else would touch my tough tiles, but.... ...I had to use a small angle grinder to roughly mark the outside of hole in order to start it! As it has no pilot to guide it, just slid around even at slow speed.

Rated 5 out of 5 by from Decent cutter Used to cut holes for pipe work, cut tiles easily. Good finish to hole, no skidding off of the glaze when started at a lowiish speed.

I guess I need an arbor or pilot drill for this

What is the product code for the arbor or pilot drill bit that I also need to purchase to use this item.

Hello. This tile drill fit straight into a standard chuck but it may be worth looking at the Erbauer Diamond Tile Drill Guide (84524). Hope that helps. Thank you for using Q&A.

How can I use this drill bit with a hand held drill

I bought this drill bit so that I could cut two holes in a tile ready for a pipe to be fitted. The bit has a centre hole in order to accommodate a centering drill bit but no means of securing it. I was therefore forced to use a pillar drill in order to make an accurate hole. Any one with the answer apart from me having to drill/tap and fit my own grub screw.

Try using a wooden template with pre-drilled holes that match the size of your hole cutter. I've made one out of 12mm ply that I place over the tile and hold firmly with my hand (don't clamp it - you might snap the tile). It gives just enough stability to the cutter to get started.
