Flintronic Diamond Drill Bit Set, 15PCS(8mm-50mm) Tile Hole Cutter Set

These are brilliant and great value for a one off project or even more if you take care of them. I cut hole sin 9mm thick Porcelain tiles no problem, just keep the speed slow and cool and wash out regularly with water and it cuts through at a fair rate. even starting the hole is easy once you get use to it just angle so only about 20% of the cutter is touching the tile and it digs right in to give you a channel to hold the bit in place while you square it up and complete the hole.

These were amazing with wet sponge, never done tile cutting/drilling before - popped it into screwdriver and at an angle and it did a great job with lots of different tiles without any loss of wear. Good stability and compatibility, cutting speed is good to my liking as it avoids mistakes. Size selection to what I needed was good. Appearance wise they do look well made and I will be lending those to my friend. Slight chipping but I'm blaming that on myself as that was the first tile cut.

I wasn't expecting much because of the price. I needed a few different sizes and looked on the Screwfix website as that is were I usually buy tools. A 5 piece set from Screwfix was 70 quid so I thought I'd try these first. I don't know how long the diamond edge will last but they cut through ceramic tiles without any problems. I used them in my pillar drill and they cut a clean accurate hole. Definitely worth the money.

I bought this 35mm diamond hole cutter to go through a 20mm thick solid porcelain slab to install a tap. It’s a tough material to get through and thought I’d give this a go as the bargain price was worth the risk. Sadly the pilot bit in the middle of the cutter is completely useless, as it melted and disintegrated within 10 seconds of use. I removed the pilot then used the main cutter by holding it at an angle and slowly tilting up as I went. Very impressive cutting speed as it easily went through the porcelain in about 15 seconds. I’ll give this a 5 star rating despite the pilot drill failure as it did the job I needed without spending too much. Couldn’t see any wear on the diamond edge, so it would appear this may last for many more jobs than I would have expected.

Useless dont waste your money

There good value but I’m not sure they will be as good after a number of uses, that said I might be wrong, however they are ideal for my needs.

Forget the expensive sets, this set of cutters is excellent. I bought these whist working away on a job, next day delivery because i had left my expensive set at home. They go through ceramic tiles like butter, porcelain floor tiles too just go slow and steady on the porcelain whist adding water and no problems. Very clean cuts with precise diameters. I can’t say about the durability as I only used 3 sizes for a total of 12 holes one of which cut 7, 6 through ceramic and 1 porcelain with no signs of burnout or wear. For the price of this set id more than highly recommend. Brilliant product !

Worked perfectly 👌 ignore any negative comments. They work 1st time to perfection.

Good for soft wall tiles but more difficult on harder & thicker floor tiles. It served my purpose to drill the wall tiles.

Pratique et efficaces !

Bought it to drill holes in a stone slab, it did the job

Coupe très bien

Compré las brocas para hacer todos los agujeros de un baño en porcelánico. Las brocas taladran muy bien, yo las utilizo con un centrador de ventosa para que no se mueva. He realizado varios agujeros con casi todas y el resultado hay sido muy bueno. Los agujeros los he realizado con el taladro a baja velocidad y refrigerando la broca con agua. También he usado la broca de 6mm y con esa no he tenido buen resultado, se quemó al momento. También tuve que realizar dos agujeros en una encimera de piedra para poner el grifo y el desagüe y los hizo perfectamente. Por el precio que tiene no se puede pedir más. en mi caso estoy muy satisfecho. Para el uso que las he dado yo me ha ido perfecto, aunque alguna ya está para tirar.
