Me too. Very durable and a pleasure to use. I bought a 55mm (i think) and it did me 50+ holes in very tough porcelain. Hardly any wear noticeable at all.

Correction - not bought. - blagged!

Just fast spinning, is it not difficult to get the hole started nicely ?

not at all, buy one and try it

 

[Flintstone]

I will add one to my order!

That Rubi grinder kit is about £230.
How many and what size bits does that include?
Can imagine that what sometimes takes 5 - 10 mins would take 5 - 10 secs!

Rubi kit Julian posted is about £50 I think.
6,8,10,12mm something like that.
I use the M14 dry bits too, excellent kit used correctly.
Incorrectly, burn them out in half a dozen holes, as my plumber found out with my kit!
As far as an esay start goes @Localtiler
Just drill a hole in a piece of board with your cutter first then place that over where u want to drill, u can stand on the board with tile below, fill the cavity with water and start the hole exactly where u want it, no problem.

These are great too:
durable foam underneath forms a dam to hold the water and you can attach a pressure water feed for vertical use.

Is it best to have a variable speed grinder or is it fine with a regular grinder?

 

[J Sid]

normal grinder for me

Rubi max speed 14,000 rpm

 

[Old Mod]

From my experience regular grinder works better.

if interested. and if you understand
I wanted to specify something.
the cutter heads for drill. they need different speeds. little faster. large slow.
while cutter heads. for grinder m14. normal speed. It should be ok.
I used the same system. of the drill, even with m14. (Now only drill and water))


just one example, where is specified rpm
