flintronic Diamond Drill Bit, 18mm Drill with Center Guide Bit, Glass Hole Saw Core Drill Bit with Diamond Surface Coating, for Glass/Tile/Ceramic/Marble/Limestone/Fiberglass/Porcelain Cutting

If you’re a DIYer and the occasional hole in tiles is required then you are not looking to spend big on holesaws specifically for tiles. And that’s where I found myself so I bought these and they did not disappoint worked very well and easily made it through 9mm thick porcelain and 15mm limestone with no wear to the cutting edge that I could see. How long these will last if used repeatedly by a professional I cannot say but they can cut. Recommend you buy a suction cut hole guide to use with as it just makes the job 100% easier and ensures the hole ends up where you want it.

Performed better than I expected for the money. Needed to bore 4 15mm holes in 9mm porcelain tiles and cut through very well.The middle piece is almost useless, so started at and angle to worked my way through slowly.For the money I couldn’t complain.

I bought these drill bits with the thought, they only need to complete one job,I only needed them for bathroom tiles and they worked fine, cut clean and sharp, decent neat finish with no pilot hole,Pretty cheap and was concerned they would make a mess of the tiles but they performed well. I wouldnt be looking for longevity from them, all in, good enough value for 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.

It's not at all obvious from the description or photos but there is no way to use these hole saws with a pilot bit. It's possible to drill without a pilot bit but it's a pain to do and depending on the material can be very difficult and causes the hole to not be perfect.Was nearly going to return them but for the price they're worth keeping for emergencies, definitely won't be using them unless I have no other option though. Can't comment on durability, just leaving this review to inform others about the lack of pilot bit and the non compatibility with pilot bits bought elsewhere.

HiUsed these wet, did drill through 10mm porcelain tiles, so for the money no complaints.

These cutters were far from useless and I would have sent them back if I hadn’t of missed my return window, if you only want to cut 1 hole with each of them that’s fine but a second hole is not happening… so I’d save your money…

Only made a couple of cuts so far, and they have performed very well. Decent selection of sizes. Great value set. Very pleased with them so far.

Quite good

Pour percer du carrelageTrès bon produit j'ai été surpris par la facilité dePerçage je doutais au départFranchement je suis étonné percer le carrelage sans effort

Duvar fayansları için yeterli markalara vereceğim bir adet yerine iki adet hemde daha düşük fiyata aldım

Muy buena para perforar azulejos, ya sean de pasta roja o cerámica. Muy importante para que no se desgaste antes de hora, es utilizarlo con refrigeración por agua.

J’ai foré dans du carrelage céramique et dans un plan de travail de cuisine en granite, j’y avais laissé 2 scie cloche Bosch et celle-ci a fait le boulot sans problème... 3,5cm de granite en diamètre 105mm en 5min . Par contre il vaut mieux faire le trou de centrage avant avec la mèche fournie...J’ai mis de l’eau en forant! 3x moins cher que bosch
