Triangular Drill Bit

[DN1986]

Anyone had any experience in using triangular drill bits?

Just looking at the one available through the TileGiant website for £25.

I hate them, ok for small holes in ceramics, useless on Porcelain and when the hole becomes larger they tend to snatch and chip the glaze. I use How to drill holes in hard tiles with diamond core holesaw drilling bits

As above, use water cooled diamond cores.

I binned mine after I had got quarter way through a tile in ten mins. Don't even know why I bothered trying it....

Not for £25 I would'nt..

 

[John Benton]

I tried one a few years ago and tbh I would just look at the the one on the website and leave it there. Buy the drill bit that will be right for the tile.

as all above but it makes a half decent plumb bob:lol:

I have one, cost £7 a few years ago and it works damn well.
Mine is a red tileeasy one.
Only works well on ceramic though, don't try porcelain as it destroys the cutter.
Mine doesn't get used much though.

Exact same as HH above, ive used mine a few times on ceramics but i dont think ive used it for 4/5 years now, Red Tile easy one,

Get yourself a bathroom fitters kit from 365 drills, you will not be disappointed

I use the 365 bits myself too, great.
I watched a joiner drilling through glazed ceramic which i had fitted, he was struggling with his diamond bit and even had water at it,lol.
I told him to use a masonry bit on ceramics, he did then and no probs.
Happy joiner,lol.
