BGTEC Dry Diamond Drill Bit Set, 10pcs 1/4" 6mm Tile Bits Hole Saw

These work well. Even better with a bit of water. You have to angle the drill a bit to start it, but once you're going they work well. I have some very hard tiles in my bathroom, I burnt out 2 normal tile drills and didn't get one hole drilled, one of these bits did the whole job, 12 holes, and the bit is still ok.

Great bits for the price managed over 20 holes on 1 bit

It says these a for ‘dry’ use, but they buckled badly whilst drilling my porcelain slabs. When I used water to cool them they performed much better. Went from 1 hole per bit to three or four. Use water and they’re pretty good.

These drills worked perfectly. I had previously purchased one 6mmErbauer drill from Screwfix, but having seen the reviews here, purchased these and returned the Erbauer, which had a very short shank anyway. These drills were brilliant. I only used two and could have actually got away with one. I still have eight brand new. Used for drilling 30mm thick granite cap stones, as a pilot drill for 25mm core drilling. The fact that they have a 6mm parallel shank throughout their length is also useful. Totally recommend

Now these bits were a lot better than I expected. The surface lasted the hole cutting and I was able to also grind some curved edges. The only trick was getting the plugs out from inside which wasn’t much of an issue. Pleasantly surprised how they chomped through some porcelain patio tiles and some artisan bathroom tiles for radiator fixings and copper pipe rad feeds without breaking a single tile. Would buy more but this set did all the jobs for wall hung loo, rads and sink pipes in a downstairs toilet with no issues.

They work well, but they are "good value" and last accordingly. You get what you pay for. Handy to have in the draw for a quick job.

Very good did what had to do with porcelain slabs got roughly 6holes for every one u

I ordered a single bit from screwfix for the same cost (slightly more I think) and didn't manage to get halfway through the job (cutting bolt holes in 20mm sandstone tiles). Thought I'd look on amazon for something before forking out for more from screwfix. When I saw these I was dubious as you get 5 for the same price as a single bit from screwfix but thought what the he'll, I should get the job done with 5. These cut just as well and lasted just as long as the erbaur bit from screwfix and would have got the job done first time. I would definitely recommend. P.S. you should have your drill speed high when using these.

Was trying to drill multiple holes in bathroom tile. Must be porcelain because it is extremely hard and thick stuff. After wearing out a bunch of carbide tipped drills and struggling to get thru just a few holes I bought these in desperation. Worked very well. I center punched and started with a 5/32 porcelain plus drill from ARTU and then followed with a 1/4" to about 1/16" deep at he shoulder. Then I went in with these diamond drills and was thru each hole in only a couple minutes. I cleaned up the holes with a standard 5/16" tile bit. Only thing to watch is that these can wander if you are not holding the drill straight. You need to rock the drill to get the chips to flow out of the hole. One drill has already completed 5 holes and still cuts well. If you need a very accurately located hole it still might be better to go with the Porcelain Plus line from ARTU but it will take longer and you won't get thru more than one of two holes without resharpening.

I purchased these to drill drainage holes in small glazed flower pots. They worked perfectly! It was quick, effortless, and effective! No broken pots and the bit still looks unused. Great purchase.

He quemado 3 brocas de tungsteno y 1 hora de trabajo, para hacer un agujero en un pavimento de piedra de granito gris. Buscando he encontrado estas brocas de diamante, y con una broca he conseguido hacer 8 agujeros de 10 mm para instalar una valla metálica en media hora ( y sigue en perfecto funcionamiento). Me parecen una brocas excelentes para este tipo de trabajo imprescindibles diría yo. Lo único es tomar algunas precauciones.- 1) Mojar la broca frecuentemente para enfriarla. 2) Como tiene un hueco en el centro, deberemos vaciarlo y sacar el trocito de granito para poder seguir taladrando, ya que de lo contrario no puede perforar, 3) limpiar periódicamente la superficie con un cepillo y el ajujero soplando con un tubito para sacar los granitos y el polvo. Siguiendo esto podremos hacer agujeros en el granito de forma operativa y relatívamente rápida.

Excellent quality. I was able to drill 8 holes in 3/8 porcelain tile to install a shower door. The first drill bit lasted 7 holes and went through the porcelain very easily. To keep the heat down, a second person was spraying a small stream of water with a garden sprayer. I highly recommend these. The last time I bought a single drill bit from home depot for the same cost of this set if 10.
