Lots of uses
I used these to remove a broken bolt remover for my Ram 1500. They worked very well; but it takes a while. I used several. Just keep them wet every 5-10 seconds.

Great quality and value.
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.

Typical low end drill bits
These draw bits get the job done, but the amount of diamond on the end of the drill. Bits is very minimal so the drill ability of it is OK don’t expect it to be faster. just because it has wax inside of it doesn’t mean that having water is not better.

Drills clean and fast.
The carbide bits in this set are fantastic. I had been using other carbide bits to drill holes in glass plates for tiered assemblies and they were marginal at best. 2-3 plates per bit. Tried these bits and they drilled thru glass fast and clean. 10+ plates easily per bit.

Works as expected and good value
No complaints as the bits cut nice smooth holes in the stone. It is a bit of a drag getting the core out but I used three of these so I could switch them out while my assistant (wife) dug out the cores, allowing me to keep coring the stone. This set is a good value.

Does exactly what designed to do
My first time drilling into granite but these bits cut with ease, simply kept the stone wet and I was able to drill 4 hole w one bit through a pretty thick piece of granite. I did cut w the stone upside down so i could see my drill marks clearly also in case I made a booboo

Great quality
Working on a big project of 252 bathrooms. These have saved a lot of money and have been just as durable as the others from the big box stores at $18 each. The get clogged and you have to clean them out, if not trash it and grab another. It’s only $3 a bit compared to the 18 and still getting 12-25 holes per bit.

Work great
They work great once you have burned up 1 or 2 in the learning process. They are pretty much one hole per use then discard. They drill porcelain tile with ease but throw away after one use and that’s completely ok for the price and getting the job done. I have bought these several times

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.

Die Bohrer sind sehr gut und preiswert. Ich musste in Granitsäulen 42 St. 10mm Löcher, 50mm tief für 8mm Gewindebolzen bohren. Die Löcher hab ich alle mit eine SDS-Schlagbohrmaschine mit 6mm auf 50mm Tiefe vorgebohrt. Diese hab ich dann mit einem 10mm Diamantbohrer ca. 15mm tief weiter aufebohrt um einen sauberen Rand zu bekommen. In dem Aufgebohrten Loch hab ich dann mit einem 10mm SDS weiter auf 50mm Tiefe gebohrt. Das ich so vorgegangen bin, hatte einen einfachen Grund. Hätte ich die Löcher nur mit der SDS-Schlagbohrmaschine gebohrt, wären die Ränder der Bohrlöcher garantiert abgeplatzt. Daher die vorgebohrten Löcher mit einem Diamantbohrer nur so tief aufbohren um einen sauberen Rand zu bekommen und dann mit SDS auf die entgültige Tiefe weiterbohren. Die Löcher nur mit einem Diamantbohrer zu bohren geht natürlich auch. Ist aber ausgesprochener Blödsinn, dafür braucht man sehr sehr viel Zeit und Geduld. Eine SDS-Schlagbohrmaschine geht dagegen in Granit rein wie Butter. Erstaunlich das ich mit einem Diamantbohrer in Granit 42 Löcher mit 15mm Tiefe problemlos bohren konnte ohne das der Bohrer danach einen nennenswerten Verschleiss zeigte. Hab mit 3000 Umdrehungen gebohrt und zwischendurch immer wieder mit Wasser gekühlt.
