Bosch GTR30

[bobbin]

Hi everyone, not been around for a while, had to move back into project management to get a bloody mortgage!
Still tiling when I can and just got myself a Dewalt d24000 and think its amazing, just done my parents bathroom in travertine and it was brilliant
Anyway, back to the Bosch, got the whole kit for £145.00 delivered from eBay brand new as it was such a good price, just wondering if anyone has used it and what your thoughts are on it?
Cheers all

The GTR is the updated Rotozip.

Got one a few months ago. Eats through soft ceramics but struggles a bit more with porcelain. Doesn't seem too good at plunging into hard stuff and the bits don't last long but it's handy to have. An easier way to get through the tile and save your milling bit is to drill through it with the 8mm bit and then use the milling bit to cut out your shape, you can be there forever trying to get through a tile with the milling bit and end up burning it out.

Have you got your technique right mate? Only asking because I've seen a couple of tilers using it wrong and burning the
tip out (x-bit for porcs and the like). I know I can plunge into the hardest porcelain in a fraction of the time of drilling and core drilling.

Not sure, think so. Putting it onto the tile from 45 degrees, tilted off the base plate and then giving it a bit of a wiggle while it's going through. What method do you use?

 

[macten]

At 45 degrees like you say but once it's made enough of a mark to not skip across the face continually give it a good
clockwise rotation keeping it at 45 degrees or a little less.

Had no problem with porcelain or a granite top I had to drill, seems to eat through it easily, slow and steady seems the way forward, don't rush the drilling.

I got told when I bought mine, that to keep the bits sharp, get a breeze block and use the drill bit on that. Supposedly keeps the diamond top sharp, and have to say, mines is till going strong. Had about 50 holes out of 1 of my bits.
Which is good going, considering this particular one has been through, ceramic, porcelain, travertine, and quartz
