Rated 1 out of 5 by from WASTE OF MONEY Drilled 4 holes into bathroom tiles before it burnt out and now is useless. Literally had it a couple of hours. Followed all manufacturers instructions. No better than the erbauer bit which is half the price.

Rated 2 out of 5 by from Wouldn't buy again Bought this and it was blunt after 10 holes even when I was cooling it down. Don't waste your money. Buy 2 of the erbauer ones for the same price. I did and the first one did 8 holes no problem. Wouldn't recommend

Rated 3 out of 5 by from Did the job, but limited life I used this to drill holes in porcelain tiles. From the reviews that I read, I thought that I would manage many more holes that in the event I was able to drill. I had not realised that Screwfix ordered their reviews by default with 5 star reviews at the top. I should have read some of the one star reviews! Anyway, the first 3 holes in my bathroom tiles went fairly easily, but (despite following instructions re cooling with water), the performance deteriorated after this. By the 10th hole, I was really struggling. I had a total of 14 to drill in total, and I did manage to get to the end, but by that stage it was extremely difficult to drill. I threw the bit away after that. Next time I have some porcelain tiles to drill, I will probably buy the same bit, but on that occasion I will have a more realistic expectation of how many holes can be drilled.

Rated 5 out of 5 by from marcrist porcelain drill. pricey bit of kit but worth every penny . used it in an electric drill as the cordless is a bit slow. like a knife through butter in really hard tiles.

My dewalt runs at 1750rpm, will this item still work well and will the lower rpm decrease its life span dramatically??

Asked by: Nic3010
The recommended speed for this product is1500-3000 rpm, however there are many factors which give different results, this can vary due to the diameter of the bit being used, the product being drilled and the operator using the drill. A corded machine gives a constant rpm where as the rpm of a battery machine may decrease as the battery life drains. The critical instructions for the use of this product is oscillation at the start, allowing the product to cool, and ensuring there are no blockages within the tile drill

Should u use water every few seconds or does this work better drilling dry only?

Asked by: gbu1
This product is filled with a wax lubricant which melts as the heat is produced, this can be used dry, however, when drilling a series of holes it is advisable to dip the diamond bit in water after every hole to allow the product to cool.

guide for the bit?

Do I need to buy one of the guide things thats shown in the pic? If so, what are they called? Only cutting 12 holes in 8mm porcelain tiles
Asked by: jayboro
Yes, we would recommend buying the guide, the Marcrist part number is 490.003.019 - Tile Steel Drill Guide, I don't think Screwfix stock this item.
