Never seen a core bit that fits on a grinder before, sounds a great tool, any chance of a link to that?

I'll read the next 4 pages later, but to answer this

Avaiable at CTD or Topps. As well as online. They're good. Mines lasting ages!

Porsadrill 70mm diamond core drill bit with Porsaclamp

Tilers forum members get discounts off all our diamond cores.

Very popular at the moment are the British made box sets which come with a free toolset including the PORSACLAMP.

 

[AliGage]

Do you produce the same that wind straight onto the grinder?

 

[Deleted member 1779]

So far we've avoided vaccum brazed (need to be run at high speeds) because we would have to import them.

We did trial some of the vaccum brazed smaller cores and they just dont last (for the money) the same as a pack of silver cores.

But the problem is they really should be run at 30,000rpm (angle grinder speed) and these cores are set to be used with a drill which will only run about 10,000rpm so too slow for vaccum brazed.

We are sticking to our range - There is not much room on the shelves !

:drool5:Would scribing the hole and diving in the middle across at various points with an angle grinder n nippers work?

my advice would be to get some parrot pinchers drill a big enough hole and pinch away

Sorry tea bag and anyone else that thinks this is the way to cut a 70mm hole, it most definitely is not... I did these holes this afternoon...I bought a 70mm diamond drill off the internet for less than £12.
I reckon including marking up the centres of 3 tiles, walking to the van to get my water feed kit, drill and guide then drilling out the 3 holes in porcelain took me less than 15minutes...
Whats the point in drilling out say a 20mm hole then spending another 5 to 10mins nibbling away when a 70mm bit will do the hole in one go...when you times that by 3 you,ve just saved half an hour. Diamond bits of the correct size are the way to go for sure Cheaper than 3 chickens from Tesco:smilewinkgrin:

Time is money, anything that saves even 10 mins of my time is worth adding to the tool box.

Angle grinders run at circa 10,000 to 12,000 rpm. Rotozips and similar run as fast as 30,000 rpm.

We stock the M14 Vacuum Brazed Core bits, they are designed to be run at 10,000 to 12,000 rpm.

Rotozip is possibly the worst bit of kit i have ever purchased,, absulute pants., sold it on ebay .
Grinders , good blades, core bits and drills are the way, no doubt .
I also have the bosch grinder with the hole cutter attachments , thats a good piece of kit , do you do the core bits what attach to these grinders alan ???

Yes we do these M14 fitting vacuum brazed bits.

There's a thread on the forum about them:-

http://www.tilersforums.com/143-tiling-tool-reviews/70653-ats-diamond-tools-dry-core-drills.html

For 6,7 & 8mm holes we now do wax filled bits which are more suitable for Porcelain. For 10mm holes in porcelain upwards these M14 bits are ideal.

Be nice to get paid by the hour and just drag the job on and on but I think the £10 a hole price is fair and the quicker you've drilled your hole the quicker you've earn't your tenner...3 holes=£30 in fifteen minutes, that's £120 an hour, think I might start a hole drilling service :smilewinkgrin:

I use my finger for filling holes, not making them [emoji12]

no word of a lie it would take m,e no more then 3 mins if that to get from a 20mm hole to a 70mm... just depends what pace you work at tbh. but yeh the best option is what you say mate and glad you found the answer you were looking for

No need to do it that way in this day and age , its like using a length of 2x1 to mix your addy or getting a horse to pull your car [emoji41]

I've got 362 horses that pull my car Craig

Seriously though, why on earth would you use old methods to do a job when the tools are available to do it more accurately and quicker :dizzy2:
