Cutting granite worktop in situ

[blackolive (Ste)]

When we re did the kitchen about 10 years ago, those massive upright fridges were’nt really a thing, and the fad was for built in appliances. The freezer on the end of the worktop run is on the small side, and will probably pack in at some point, and the built in fridge has been moved to make a beer fridge, and we have a stand under fridge. Im thinking if I remove these and the end wall units we could have a big fridge freezer.

the run of granite worktop and upstand would need cutting. If it were a straight run it may be feasible to take it out, but its bonded to the breakfast bar so would be a massive job to remove and make good again. The granite place don’t do alterations.

I was wondering about the feasibility of cutting it myself with an angle grinder and new slotted diamond disc, the granite place wouldnt commit to saying it could be done, and mentioned the massive amount of dust that it would generate, but wondered if anyone on here has done anything similar and whether it would be feasible, and not look like Id cut it with a knife and fork, wondered whether a strip of wood could be used as a guide to get a straight cut. ?

Yes it can be done, the dust is pretty awful

Fine kerf continuous rim blade and good extraction are key

Diamond polishing pads to finish

Where are you?

A good man and a 12" Stihl cutter could cut that with a hired extraction unit, when you get to the wall run the saw vertical to get the splash back on the same cut...might then need a bit of dressing at the edge,remember its only a slab of stone at the end of the day

Chorley in lancs. Would the dust be too much for the old aquavac ?

yes...hire an extraction unit with the big pipe right behind the saw...2 men needed

 

[mike os]

Yes Hire a professional unit.

My festool extractor with autoclean barely copes....

I've cut slate slab (real soft in comparison) indoors, with a 2 stroke disc cutter.

The bit that near killed me was the 2 stroke fumes!


If you cut it indoors, be aware that for months after you will still be finding the dust. Other than that, im sure it can be done.

Makita do a 12" 4 stroke cutter now, i bet hire shops have them to save the hassle of damaged tools through lack of 2 stroke oil from amateurs

Electric disc cutter and proper extractor.

Electric disc cutter and proper extractor.

As above, then hire a couple of industrial vacuums, one on the grinder another catching the rest, cover everything in dust sheets, you're going to get dust everywhere anyway.

It might need a 12" blade to get into the corner/splash back, apart from the Sthil cordless who else does an electric 12" cutter? i cant think atm.

Evolution used to, the one I used was good

 

[mike os]

No shortage on 12 inch electric grinders but a 115mm will do just as well

 

[angellonewolf]

seal off any where you can taping round door frames etc helps and leave overnight before removing

Ive never used one but Ive seen diamond jigsaw blades for sale that cut granite tiles. May do most of your worktop And grinder on the splashback.

I could do it while you are cooking.... and you wouldn't need a mask....but you do need best part of 2k in kit

Got to be cut in situ and what happens at the wall corner end

 

[gaz1]

i cant see other end but he should beable to unscrew from the top and slide the top forward so he could cut all the way across he has to decide weather he wants to seal up and cut or both

but he still has to move the top anyway to cut to the back of the worktop + hes only movin the whole top 3-4" forward to cut it so well supported

all the granite tops i have come across have been bonded with mastic adhesive to the top of the units
