Grinding confusion

[Tile Shop]

This is probably going to seem like a very stupid question, but I gotta ask, because i've seen something that goes completely against something else i was taught a while back.

When grinding a tile, I always make sure that the blade spins down onto the tile. I was told years ago that if the the blade spun upwards, it can lift the glaze or cause chipping. It would also throw dust up in the air instead of down to the floor.

But the genesis dust extractor, requires that the blade spins upward to unsure the dust is directed to the exhaust port...... surely meaning the cut won't be as clean?

Confuzzled and would like your thoughts.

Depends on the way your cutting it, a cutter with a wheel mounted on the bottom which cuts from the back of the tile, they don't chip the tile.

 

[Kyle Knowles]

I have the festool grinder and that cuts upwards also I always scribe a line first if I use it but I've not used it that much

 

[Old Mod]

Got a pic of it @Paul C.?

Better still. Theres a video on protilers website:

How much is this ?

 

[Tile Shop]

I always have it the other way (blade on the left) so the dust is thrown under the tile, but concious of the dusty mess it leaves. Thats why i'm looking for something like this.

 

[Kyle Knowles]

I have a grinder and a dust extractor and my opinion is it's just as easy to set up a wet cutter

 

[Tile Shop]

How much is this ?

£48. Which i think is pretty expensive for a bit of plastic/metal. Sure it'll be cheaper elswhere.

I have my grinder the other way. Blade on the left and yes it does make a mess of the floor and your leg. I've had a wet leg today. For me the beauty of the grinder is its manoverability and its convenience etc, I think putting a hoover in the equation might cancel that out!

Better still. Theres a video

Start the other end and pull it thro the tile. Blade cuts right way and dust is thrown away from you.
If the grinder snags, it comes toward you and your instinct will grip it tighter.
It's much safer and that's how the majority of stone guys use them.
I've been using a grinder Ike that for over 10 years now and it's much better once you get the hang of it.
And it's easier to see your cut line.
Not being able to see the guard close up in the video, I can't quite tell what you can and can't see, but you'd just have to compensate with tha marking of your tile so that you can run the guard along it.

I'll give it a go. Stick some gogs on and try without the guard, see how i get on. From your experience will it still collect all the dust with a vacuum attached or will some still be lost downwards?

I've been using the grinder cutting marble all day in someones bed room!

Not tried that way with dust collector tbh, but it's certainly a better way to cut all round.
And it will push all the dust forwards, yes.
You can do it one handed and hold a vacuum in front of you, but that takes a little more practise 😀😛

Well.... practice is something i can get plenty of. Got my kitchen to do before xmas and the skirting in the conservatory still to do.

Our fridge freezer packed up so the landord thought it'd be a good idea to get that and the unit ripped out so a free standing one could go in its place....... the wall behind is a fookin mess and theres a hole in the floor covering. So they're letting me loose on tiling the walls and the floor.

 

[Tile Shop]

And after showing her a few serving suggestions of tiles and inspired by @Andy Allen 's jotm winning effort, this is the wall tile and layout she wants to go for.

 

[Flintstone]

You dropped one there showing her that didn't ya!

 

[Tile Shop]

And to test my cutting abilities, for the floor we're having the Marazzi Denver beige 60x30, brick bond, with a 1 inch border cut from the black tile of the same range.

Good job i like a challenge but will be a good test for a beginner.

Also need to practice mitering with the grinder too..... for the window reveals. Luckily i have plenty of tiles to practice with before i start.

, with a 1 inch border cut from the black tile of the same range.
.

you're going to have a 1inch border around the perimeter?
Not a good idea mate, not unless you can guarantee the room is perfectly square or the area that you're tiling is.

It won't be up against the wall. It'll be set in by about 300 ish, so if the walls are on the wonk, i can lose it in the cut without compromising the layout.

I need to loose lay them when i bring them home, so will do some trial cuts and post some piccies up and take some expert ideas and guidance.

I use this

I got one of these a while back from amazon link below:

HERZO 115/125mm Plastic Dust Extraction Cutting Guard for Angle Grinder https://www.amazon.co.uk/dp/B01G501XTK/ref=cm_sw_r_sms_c_api_.M0pyb038SFM6

But I have so far never even tested it out!

 

[moomarine]

You can't get this bit of kit anymore can you?

 

[Old Mod]

You can't get this bit of kit anymore can you?

Apparently not.

 

[moomarine]

Apparently not.

It's a shame because it looks good. Hate using my wet cutting when I can't cut outside!

That's how I was taught to use the grinder over 20 years ago now keeps dust going away from you as you cut
