Hello, all. I recently bought a 7" wet tile saw. Nothing fancy, just
an inexpensive Home Depot saw. The saw does a great job of cutting;
however, on some types of tile, at the end of the cut it tends to chip
or break a corner off the tile. Does anyone know a way to prevent
this from happening? The only thing I've found that seems to help is
to slow down the tile feed to a creep as I approach the edge of the
tile, but this does not always prevent the chipping.
I've had the same issue from time to time. The cause is that the
blade is "prying" the tile apart, and when you get near the end, the
last little bit of tile breaks off. You have the solution - go slowly
at the end. You could also cut partway from one side and then turn it
around and finish the cut. The ultimate solution is to get a serious
saw - not cheap.
I have a HD 7" tile saw. The blade that came with it had a very slight
wobble to it, it cut fine but would crack the tile at the end of cut
breaking the last corner off if you went a little too fast. I changed the
blade for a better one, now it doesn't wobble, and cuts fine.
With all the saws that I have used owned or rented, the last 1/4" of the cut
is the most critical as there can be tremendous stress on that last little
piece of tile. Caution and slow feed is always the best method to get a good
cut when at the end of the cut.
Yes, sometimes flipping end over end and cutting a 1/4" in will help, with
some tiles it causes the glaze to chip when cutting glaze side down, and
when not using a fence or other guide it can be difficult to align the
bottom cut with the top, or it will not work when cutting a 45 degree mitre.
The other suggestions about going slowly at the end are good, but I
also found that supporting both halves of the tile for that last 1/2"
works wonders. Luckily, I bought a bunch of extra field tiles to
But both the OP and Andrew talk about supporting the tile at the END
of the cut. You push the table forward, and the tile goes into the
blade, sometimes hanging off the table at the start of the cut. At
the end of the cut, the tile is better supported than at any time
during the cut. Is there another type of wet saw with a different
type of table?
Put another scrap tile firmly behind the one you're cutting, so as the
blade breaks thru the first tile it starts cutting the scrap.
(Actually, it starts cutting the scrap before it finishes the first
tile.) The scrap will support the back edge of the one you are cutting.
The tile is already fully supported from the bottom at the end of the
cut. You need to also support the back edge if your tiles are chipping.
That's the best i can explain it. Good luck.
