Gunpla 10 Pieces Drill Bits 6mm Glass and Tile Drill Bit Set Tungsten Carbide Drilling Tool

I brought these bits thinking it would take a few to drill the wall tiles. Was i wrong. The first bit drill all 12 holes no problem and would possibly drill more.Good quality and value

excellent price drill well and clean

I burnt out the first bit because I didn't keep the tip cool enough and was going to chuck the rest in the bin. Then I found a brilliant video on YouTube by an Aussie guy who had also had a problem drilling porcelain wall tiles. He discovered that you need to use a 'pulse drilling' method to get through the tile and it worked perfectly. Just set the drill to high speed hammer action and pulse it on and off for about 5 seconds until your through. It's also worth wetting the bit regularly just in case it overheats

I had an absolutely nightmare trying to drill through some bathrooms tiles a few weeks ago. I had a drill bit, which looked a lot like these, but it honestly took me over two hours to drill two holes. I was literally sweating trying to do it. While I did so the drill bit eventually broke because I had been using it for so long the heat just ruined it.With these, I probably took less than 30mins to drill four holes. I couldn't beleive it. They are perfect and better than anything you will spend a lot more money on in a DIY store.The only thing I'll say is I don't get the orange coating. It comes off pretty quickly, but to be honest that had zero impact on performance.To drill the four holes I used one drill bit and it remains intact to drill another day.

As along as you do not overheat ( at which point they fall apart) these drill the hardest porcelain tiles well

Did manage to drill holes in tiles but it was not like a knife through butter as someone claimed, and drill bits could only be used once as they burnt out.Dogberry.

I've worn out a lot of tile drill bits lately, lots of different makes and price points, making holes in some really tough 9mm ceramic tiles. I am using the slowest speed possible, no hammer action, and irrigation with water during drilling.Usually what happens is they start off OK-ish, then within a few holes, cutting slows down a lot. Finally the tungsten carbide spear point falls off after 2-5 holes. I accept these things are disposable. I haven't tried the really expensive B*sch Pro type, just too costly.So I bought 10 of these Gumpla bits, not expecting much because of the low price. Wrong! They are good. They are a little more difficult than most to get started without wandering, but I can't be bothered with masking tape. The tip is, I think, ground a bit different - less of a needle point. However, once started they are fastest to get through the tile of any I've used. Even better they are still cutting pretty well after 5 holes, and I've not yet had a tip fall off.I wish I'd tried them earlier. I'd have saved £50 on the others, from DIY outlets, which cost more and were worse.Bonus point: the set of 10x M6 came in a nice case, not shown in the Amazon ad.

I bought these to drill through porcelain tiles and might have had more luck with a sharp stick.First one snapped, second one lost its head pretty quickly and the rest blunted variously.Used five drill bits for two holes.Also worth noting they are greasy as a teenager so you'll need to give them a good wash. Again like a teenager.I'll be sticking to Bosch bits but if you only need to do this once ever and have nerves of steel then these may be a lively way to add some excitement to your day.
