Tile cutter blade

[Davey]

I need a new diamond blade for my Wickes wet saw electric tile cutter.

The old blade is 180mm x 25mm bore x 2mm thick.

Wickes sell these but they are expensive and don’t have very good reviews.

There doesn’t appear to be much choice as most of the 180mm blades I’ve seen are 25.4mm bore.

Will a 25.4mm bore blade be ok or am I stuck with the Wickes blade?

I know 0.4mm isn’t much but I don’t want any accidents when this thing is spinning round!

Thank you

Diamond discs are expensive. For example a montolit 180 for Porcelain is £110ish.

If you're after something cheap, check on ebay.

Thanks Sammy

I’ve looked on eBay (and Toolstation and Screwfix) but most 180mm diameter discs seem to be 25.4mm bore (1 inch).

The old disc states the bore is 25mm (metric) so a new disc with 25.4mm bore will probably be too big for the shaft.

I’m not sure why Wickes make a tile cutter with a metric shaft - presumably so I have to buy replacements discs off them!

Have you got a caliper you can measure it exactly?

These sizes are usually standardised, so it could either be they've written 25 as a generalisation or they've got a disc that is 25mm to stop you buying others.

Ideally you need to accurately measure the opening and Arbor plate but .4mm is a hairs width (well, not quite but you get the picture) and I wouldn't even consider it.

O.4mm will be for clearance. It's not a bearing face so you want to be able to just slide the new blade on, not have to tap it on.
Fit a 25.4 blade, make sure the guards are in place and switch on. If it wobbles/vibrates then clearly you have got a 25.0mm arbor but I think it will be fine.
You do know, I take it, that after fitting a new disc you should check it's secure after a few cuts.

Inertia will clamp down the securing bolt.

Still a sensible idea to check it though. Only takes a few seconds but could save serious injury.

If you insist but it would have to deny the laws of physics for it to back off.

IIRC the Rubi discs have a punch out in the centre, thereby allowing you to use either diameter. I think the Spectrum blades have then as well.
