Marcrist PG850X Double-Ended Diamond Tile Drill Bit 6/8 x 150mm is rated 4.2 out of 5 by 11.
Rated 3 out of 5 by from Very Important I bought one a few months ago and it performed well initially, however only today I found out (from the Marcrist rep at a trade show) that you have to tap the drill straight after drilling to remove the porcelain plug. When he showed me today I saw the wax run for the 1st time... Maybe most trades people know this already (I certainly didn't ... hopefully this will be helpful to some :)

Rated 5 out of 5 by from Tile drills I have 800 hole to drill through grade 5 porcelain tiles,I have tried a number of branded tile drill bits and these are by far the best.

Rated 5 out of 5 by from Great tile drill I was struggling with my usual wet cut diamond drill bit when drilling multiple holes for shower screens, towel rad etc. Each hole was taking up to 20 mins in hard porcelain tiles. So I purchased this drill bit instead and it decreased the time per hole to under 5 mins, saving me time. It is expensive, but it performs really well.

Rated 5 out of 5 by from Quality Good quality drill bit that makes little work on hard porcelean tiles, i start with 6mm then open with bosch multi construction bits if need bigger hole. Reduces alot of time but lost my drill bit so cant comment on its longivity. worth it if you get 50 to 100 holes out of it though. macrist are great at making tools for tiles

Rated 1 out of 5 by from Dreadfull I don't write reviews but this bit is a complete waste of money. No point on the end it wanders all over your tiles. The claimed longivety is laughable. I managed 11 holes in total before its blunt as blunt can be. No matter what speed you run it on your better off waiting for wind errosion than trying to drill through tiles with this bit. Will be contacting manufacturer for a refund. Do not buy this product.

Rated 3 out of 5 by from porcelain tile drill 15 holes on the 6mm end then died. 3 holes on the 8mm end but struggling for more. Am i just unlucky in that i have the hardest of fatherless of tiles to drill? Conclusion ? NEVER USE PORCELAIN TILES FOR WALLS THAT NEED DRILLING TO FIX ITEMS TO THEM. THE COST IS VERY CLOSE TO £2 PER HOLE TO DRILL. Athough this item is good i feel it is overpriced for the results. By comparison i could have used cheaper products and spent the money on the quantity of drills needed for the same amount of holes drilled .It may have worked out cheaper.
