Dry Diamond Core Drill Bit Set,BRSCHNITT 2 3/8 Inch (60mm) Diamond Hole Saw Core Drill Bit with Triangle Shank for Porcelain Tile Ceramic Stone Granite Marble

Used to cut a hole in the bottom of a glass bottle. No issues, it went through well. Easy enough to use of you don't put too much pressure on. Start with an edge first as going for the full bit cause it to skate on the material. One is began to cut you can then work the full edge in.

Great little cheap cutter Got 4 holes out of it for uplighters on 20 mm porcelain slabs outdoor Used garden hose to keep water on it Not sure if made difference

Ok for money did job

Ordered this to try and make a hole in a 38mm stone paving slad , glad I bought it , it easily cut through the slab with the use of water to cool it down , went through in a matter or minutes (did have to tap with a hammer as didn't go all the way through , about 1mm short) .. did not loose any of the diamond coating so not a single use item .. Only problem is it's tricky to get started ... but once you do it's a great bit of kit and great valve for money

Bought these to drill two radiator pipe holes in ceramic tile. It worked, was slow going and I used up both bits. Don’t use these dry, wet they worked. As a cheap way to drill a couple of holes they worked, not recommend for more serious use than that, I wouldn't expect to get more than one or two holes max per drill bit.

Woow

These are great, so much cheaper than screwfix!!!

Had to drill a hole in the cistern to change from a handle to push button flush(don't ask why) and this worked just the treat.

Al principio,no me decía nada . Pero al usarlo es bueno, cumple y es barato .hay que usarlo con inclinación para que marque en el material y luego enderezar ya que no tiene broca. Desbasta bien. corta bien buen acabado

These are excellent value. Drilled through porcelain like butter. If I had one minor complaint it would be that they could do with 4 slots for removing the core after drilling rather than just 2, but I don't feel this is significant enough to reduce rating. So much better value that store-bought alternatives.

Ik heb maar één gat in een keramische tegel moeten boren ( met water ) en het boor was super scherp ! !

Hice un par de agujeros en piso de porcelanato

Worth every penny, just start cut on an angle about 30 degrees and make a lip around the cut area to hold some water to keep blade cool, (will also make it last a lot longer), stop after every 30 sec and pour a bit of water into well of cutout and you’ll be very happy with the result.
