We want to replace our gas hob with an electric induction hob (already bought on PH recommendation) in our 4 year old house. We have 'Star Galaxy' black granite work tops and unfortunately when we came to fit it before Xmas, we found the current hole is too small. It needs a 10mm x 500mm strip cut to allow fitment of the induction hob.

I've contacted a couple of stone masons who have quoted £120+ to do this and will be *very* messy. Is there an alternative? Could I possibly use a ceramic tile hand saw - would be a PITA to do, but it's such small slither, seems expensive and messy to do otherwise?

We have looked at other induction honbs, but they all work of a standard size hole, which ours isn't!

£120 doesn't sound that bad to get it done properly.

Trying to do it yourself will probably end up costing you an awful lot more when you make a mess of it and have to replace the whole piece of granite...

Angle grinder with a diamond disc. 10 minutes work but very messy. Would suggest you get somebody with you with a vacuum cleaner as you cut.

I know an angle grinder is best, but I meant a hand tile saw - is this even practical? I wouldn't attempt an angle grinder myself.

The stone masons seem reluctant and won't even offer insurance to do it if it went wrong.

You may get away with using a jigsaw with a ceramic cutting blade like this.....

I'll text Wifey, She's in charge of fabrication at Mandarin Stone.

Unless there is sufficient width left in the granite then you may need to trim two strips off.

Hand saw is going to take ages assuming a suitable blade can be found, mechanical cutting is going to be messy.

£120.00 doesn't sound too bad assuming it includes a reasonable clean up and you've emptied the kitchen. Not surprised they're not willing to gaurantee the worktop it is very likely to break regardless of the care taken.

Anyone want to buy a new, unused IKEA induction hob!!!

Unless anyone can recommend an induction hob that will squeeze into a 47cm depth? Standard size requirements are 49cm

Or just run water over the cut. Will cool the blade too.

Just make sure you're not standing along the same axis as the blade or you're gonna get wet biggrin

I fit granite and the like,bad news I'm afraid......unless you can remove the worktop you won't get clearance to use the wet saw.only option is a small grinder with a diamond blade and a good hover.just get plenty of plastic dust sheets and a lot of masking tape for surrounding area.its tough old stuff so just take your time with it.hth.
