I have been away from Lumberjocks for a few years and have only worked sporadically in my shop doing mostly small projects. I have a DeWalt DW750 mitersaw, using the original 60 tooth blade, that is driving me nuts. When the saw is turned to cut 45 degree angles the blade is not cutting square. When the saw is turned to make 90 degree cuts they are square. I clamp the work in place before cutting so the material doesn’t drift. Is the problem a crap saw, a crap blade…...or a crap woodworker?

Try some cuts with a slower feed rate. I’ve
noticed when beveling with miter saws the
blade can deflect when the cut is made quickly.

That said, in recent years I’ve seen a lot of
complaints about miter saws not cutting right.
There’s a lot of pressure on the makers to
deliver a product that hits price points. Perhaps
the older ones (I had a DeWalt made in Italy)
were made better, or perhaps woodworkers
are expecting more precision from them these

Hard to say, but regardless, the stock blade isn’t stellar and would an excellent candidate for a replacement with something better.

I got a blade from Carbide Processors. I have the same saw but it is one of the first made. Go on Youtube and there are videos on how to true a miter saw up.
I have found that if on wants a tight 45 joint I always use a shooting board.

I prefer to use a miter jig on the tablesaw. Personal preference but I did you the miter saw for a long time and often was frustrated with the results that needed fine tuning, sometimes excessively so. Having seen and heard about them for years I broke down and made one. Plenty of designs here and on the web to look at.

Regardless dump the stock blade, much better performance blades to be had.
