Just wondering ...

We get told about this a lot.

Basically installers knock out the back of tiles with a grinder. Its done a lot too on the continent.

The main dissadvantages are:
1) Smaller holes like fixutres and fittings cant be done this way. Its difficult to position the holes.

You could never achieve this level of accuracy with a grinder.
You could never grind out the holes once tiles are fitted.

Drilling from the front is far more accurate.

Holes drilled from the front are milimeter perfect and accurate.
The level of finish is the ultimate. Can be grouted or siliconed.

In contemporary bathrooms its all about minimal looks.
Capping plates can look ugly.

Capping plates over freehand drilled holes or grinder made holes can look ugly.

With the use of a water cooled sponge its arguably cleaner and safer.
You can control the speed of the drill and collect the dust with a wet sponge.

With an angle grinder its fierce, hot, very dusty, noisy.

You are also restricted to the lead. An angle grinder is tethererd so can restrict movement.

You could never do this with an angle grinder.

Also for specialist holes then you need accuracy.
Our cores drill holes in toilets, sinks, urinals, shower trays, white porcleain goods.

Also there is a safety aspect. Angle grinders like fire are a great mistress but a bad master.
Accidents can happen. For proof of that we can provide links to angle grinder accidents.
But they are too gruesome to print here.

Our suggestion is a set of the multipacks for £7 a drill which is great value for money.
Its worth having in your toolbox and will we think make your life easier.

Check it out ,
Both holes marked and cut in under 8 minuets ,
Its the way iv always done it and works fine , accuracy just depends on how well i mark it .
I can do small holes , big holes , whatever , no problem .
What do you think??

 

[Marcusko89]

I agree with the noise dust etc tho ...

 

[Marcusko89]

I will definately get a drill at some piont, cheers for the info, also..
How does speed etc compare ?

 

[Marcusko89]

I may be proven wrong but I can’t see some of the holes I have to do being neat enough without a drill.

Iv done this with my method and its been perfect , although i imagine it would definatly be easier with a drill ; )

I think that drilling will save you a lot of time. On a ceramic tile I reckon you could go through it as quick as the first cut of the grinder. There is nothing wrong with doing it your way, its just that if there are quicker and easier ways of doing it, why not do it that way? Get your self a set of the 365s and let us know how you get on with them. I think you will be impressed

 

[Marcusko89]

Thanks fo the advice guys , il let you all know how i get on and update this thread when ive tried'em'out 

Looking good as a project. I would certainly agree that its a useful technique and that diamond grinder shown above is a lot different to an angle grinder. Its an diamond core attachment rather than a blade so less likely to do any injury.

We have discovered many ways to get those pipes through tiles! Heres a classic example:

The intention here is to cover them so its not important how they get through the tile.

Am sure that tilers have many varied ways to get through the tiles. Room in the market for all.
As mentioned the downside of the grinders are the dust and speed.
You also have to have a lot of skill and patience. Its not easy to grind from the back and get the result to the front.
So congratulations on a skillful use of a tool !

But obviously when it comes to the small rawl plugs then there really is only one way to do it. And thats from the front. And with a drill.

£99 for a pack of five

I must admit I used to do it this way, with the grinder, even use the German G clamp and tungsten pin hammer. But I think the core drill is the way to go imo.
