Thanks,

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.

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.

Flip over end to end,cut in 1/4" and flip back and continue the cut.

Might be the tiles. Denser, higher quality tiles from a tile store
will be less liable to chip.
If you are using the fence, make sure it is perfectly parallel to the blade
or it will chip the last little bit every time.

Push the tile with a scrap that backs-up or supports both sides of the
cut, and go slow.

Am I missing something? My saw has a sliding table that supports the
whole tile. Are there saws where half the tile hangs off the edge of
the table??
JK
We're talking about supporting the *back edge* of the tile when you cut.
Bob
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?
JK
Sure. There are bridge saws (like a RAS)...saw moves, tile doesn't.
There are saws with a non-moving table with fence (like a wood table
saw), tile is pushed into the blade along the fence.

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.

Are you cutting porcelain? When you cutting hard porcelain on your
tile saw the diamond in the blade will start to round over. You may
need to use a dressing stone on the blade. It is an abrasive stick
that you cut into with your blade. This will expose new diamond and
should help with the breaking of the tile. Contractors Direct carries
a good one <a target="_blank" href=http://www.contractorsdirect.com/

on <a target="_blank" href=http://209.35.48.178/BERT/saw-comparison/

Try cutting 1/3 from one side and 1/3 from the other and finish in the
center. Experiment cutting different ways until you find one that
works. also try not to put too much hand pressure or saw blade
pressure on the tiles.
