Widening a pinched porcelain tile joint..............

[Longshot001]

I was having some tile work done in a tub surround and a couple of the joints are pinched. The majority of the joints are approx 1/16" but a cpl are almost nil. Is there a rotary bit/blade/disc that could cut the tile to widen the joint enough to get some grout in there. The edge that would be cut is the edge that was cut to make the tile "fit".

Thanx a bunch

On this side of the Atlantic we can buy slitting discs for an angle grinder, either in 1mm, 2mm or 3mm thicknesses.
The outside diameter is typically 115mm and the internal bore is 22.2mm.
These would work well if you can get them over there!
