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

I was attempting to drill 12 holes into a brick wall to hang a large TV. I can't use a hammer drill because it'll break the brick. I used a regular drill and a carbide masonry bit...3 different ones and after an hour or so I made one hole. That's wasn't reasonable. I searched for something different and it led me here. I had spent probably $50 on several other bits that weren't working until I came across these. Once I got them I immediately tried them out....or one I might add. It worked so good that only one bit drilled all the rest (11) of the holes. Took about 3 minutes to drill one hole compared to an hour. TIP: If using in brick, drill speed at a medium speed and medium pressure. More pressure for less speed. Don't allow the bit to get hot. Drill for 20 seconds and dip the bit in water to cool. Dry it off and repeat process. It works very well if you keep patience. Avoid using water for lubrication unless it can be fully submerged. A dry bit is fine as long as it isn't getting hot. NOTE: This bit is NOT designed for metal of any kind. Good luck!

Great Bits. Used to mount grab bars in ceramic tile shower. Could get 9 or 10 holes out of one bit. The $14 each bits from lowe's were only getting 3 or 4 holes per bit. A real bargain. The trick is to get a spray bottle with water and keep a light spray on the bit while turning. The water doubled to life of the bit. Also kept the dust down.

I had a lot of holes to drill in bathroom wall tile for shower partition, shower bar, toilet holder, towel bar. I got between 1.5 and 2 holes per drill bit. Start at an angle, then as you get a little purchase, slowly go to vertical and drill straight in. The edges of the top chip off and it gets kinda bumpy starting the 2nd hole. By the 2nd hole, they're still going but a lot slower. Also these are not a full 1/4", so if you're using wall anchors, finish the hole off with a real 1/4" tile drill, and life will be good.

Wow!!! 4 holes with a single saw bit in under 5 mins thru hard porcelain wall tile. The last hole did take a bit longer then the first as it the bit I imagine began to dull out a little bit. But a HUGE time saver!!! It would take me more than 30 mins with wet saw bit (and a helper spraying water and clean up) and possibly 2-4 bits. These saws rock and for the price, even if they only last each 5-10 holes, they would pay for themselves in reduced labor!! Recommend for DIYer!!!!!

Great product, with quality cutting head, long lasting bit. I drilled 9 holes through thick glass with one bit.

Work perfect on porcelain tile.

First of all, these bits are priced very reasonably. In the big box stores you might get 1 or 2 at most for the same price. I am a tile contractor and have used many different bits to drill through tile for installing grab bars or shower doors. These bits drill or grind their way through a hard porcelain tile quite easily. I start my holes by marking the spot to be drilled, etching a small starting point for my bit so that it is less likely to travel on the tile surface and then starting my bit at an angle till it begins to drill through the surface at which time I hold the bit vertically. I drill for about 10 - 15 seconds before dipping my bit in a bucket of water and putting a little water in my hole, keeping the bit cool and also extending its life. I do this approx. 4 times before the hole is completed. The bit is actually grinding a hole versus drilling a hole. I am very happy with these bits and will reorder in the future.

I’ve been tiling for almost 10yrs. These drill bits were used against 3/8” porcelain tiles and lasted 5 holes per bit. TIP: if you are drilling on hard tiles (granite, porcelain etc ) and the holes need to be perfect aesthetically visible and not covered by any hardware, you should NOT push its limit and discard after 4 holes. Otherwise, the performance of these bits rapidly deteriorate taking way much longer to create holes and worst part, it starts to “dance” around creating a bigger hole! For a contractor or DIYer, It would be much cheaper and less trouble to keep replacing the bits than demolishing a tile job and start all over again!

Testat. Flera olika, koremantborr. Men de här. Är totalt bäst. Vaxet ihop med hög hastighet gick jättesmidigt. Kan varmt rekommenderas! 👍

forets utilisés pour percer du carrelage extrêmement dur. Perçage bien plus rapide qu'avec le foret spécial acheté plus de 30 euros chez Leroy Merlin, et plus de trous avec un seul foret. très satisfait

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.

Fantastiche! In precedenza avevo comprato una punta di una marca molto nota(quindi anche costosa) per fare 3 fori sul marmo e si è rovinata quasi subito anche se usata con acqua e a bassi giri, poi ho comprato queste convinto che mi sarebbero servite tutte per terminare il lavoro... beh, con soltanto una punta, maltrattandola usando tutti i giri del trapano e mettendo tutto il mio peso non sono riuscito a rovinarla! Complimenti all'azienda

Drill bits work great and the price is even better.
