what brand of diamond cutters do you use...

Bri it is is not just the quality of hole cut t hat matters because to be honest most holes are covered by a cover plate.
But from my experience it is fact that a quality bit that might cost many times more than a cheap bit is so much more cost effective in the long run.
i guess it all comes down to how many holes a tradesperson drills on a regular basis.
We have 15 quality drill bits in the box which has cost a lot of money but long term for a professional that drills regularily this is a must.
if you want me to expand further i can do so from experience but I would rather not reveal what I really think here about the cheap bits that are ok for one off or a couple of jobs.I do not include ats drill bits in my thought s as I have never tried them.

What are your preferred choice of bits..which is the reason for my post..to find out what is more cost effective..Im currently working in saudi training guys to install hygiene equipment in hotels and offices..kitting them out with the correct tools..some have bits of wood as hammers ! ... they always tend use the grout line, but doesn't always mean the items they are fitting are symmetrical or work from a centre line, and most, if not all stuff here is Chinese rubbish ! ..so want to import some decent stuff as a lot of the tiles are porcelain.. and are doing some 72 holes a day using 5 mm plugs..so want decent as I am finding doing appraisals for these tech... that cheap is costing them more in time and money..out of 10 hrs a day 6.8hrs is gaffing !

I will be honest and if I have ever needed to drill such a hole with those sizes , I have never managed it. The bit just folded over and disintegrated.

Well there lies the answer does it not.!!!
try a Marcrist 6mm drill bit and then come back and report.
i will add that I don't just use Marcrist.
Horses for courses is the expression is it not ?
sorry , I just have a real bug bear about the cheap rubbish drill bits on market.
sell them in DIY stores . That's fine
but for suppliers to come on a forum and suggest that they are for professionals and try and compare them with a quality product that surprise surprise costs loads more is insulting.

Ian.....smaller holes I.e 6mm always burn out the quickest IMO......but if you are paying sub 10p per hole you are on a winner IMO........and you can get that from a top of the range set of drills or some good quality cheap ones.........personally, if you are working with guys that are not familiar with expensive kit then I would not give them it (you need your drilling speed right, hammer action off, torque cranked down etc..).........
I would supply them with the inexpensive option that way it only costs you £2......not £60.......but thats me.....

more horses for courses Eh Johnny!!!!

enjoy you night mate......great stuff you are doing BTW!

Cant comment on the 6mm but I do have a 115mm Marcrist and a 365 drill and no difference.
Also a 65mm 365 drills and lost count of the holes that has done. Its the smaller ones I have trouble with although I do have a 8mm Marcrist, I dont drill those holes.

well thats all part of the training we are giving them..also the tools are their responsibility...if they loose or abuse it will come off there 1/4 bonus...

sorry just getting carried away. I have seen your trials with drill bits and what you chose to reveal and what you did not!!your trial was spot on.
im sure you you know what I mean,
But it just frustrates me that people on this forum may be getting the wrong impression about diamond drill bits in general.

I've tried quite a few different ones but at the moment I favour Marcrist dry bits. I find these give me a good combination of speed, longevity and purchase price.
