Chop Saw Wheels turn about 3600 RPM.
My grinder spins about 10,000 RPM. If a chop saw wheel were
somehow mounted on a grinder, the grossly over reved wheel
would be more dangerous that a gernade with no pin.
Have read the other posts here, and agree with the fact that using an
angle grinder may not give the beat results. In our school workshop we
have a chop saw that uses a 1" by 14" blade. Switch on, after setting it
up, and just walk away. As it finishes the cut it switches off
automatically, great when doing lots of repetition work rather that the
odd one off.
But you probably knew this already, so for the help I thought why not
try one of the more expensive compound mitre saws, like this one:
Most of the larger ones have an all metal guard so can use grinding
wheels. Pop in a grinding disk and you have a very accurate chop saw.
Lots of money though for one off use.
Best of luck E
If you insist on the angle grinder, you could mount the grinder in some
sort of hinged holder. Plus you will need a decent safety shield. For
safety purposes you must NOT USE AN ABRASIVE DISK LARGER THAN THE
ORIGINAL GRINDER DESIGN. If you do, you will overspeed the disk and run
the risk of blowing the disk.
Ok, so I will state the obvious...and tell what i did...at a "yard sale" I
bought a Hitachi 10" miter saw for $25.00 Sure it was older and needed to
have the pivot hinge tightened up a smidge but the darn thing works real
DO REMEMBER TO ADDRESS THE DUST REMOVAL ISSUE. Mine had a plastic director
that simply melted on a long cut. I replaced it with a simple sheet aluminum
shroud to blow away from the front of the saw. You may also want to shield
any motor openings/vents to keep the metal dust out of the brushes etc.
I can't imagine the time and materials needed to turn a right angle grinder
into a cutoff.
Tater inquired about turning A grinder into A chop saw and to this I
Horrible Fright sells an adaptor to turn A 4 or 4.5 inch angle grinder
into A chop saw but ,to me, it looks like a waste of good metal and time
screwing with it.
In my opinion you would be better off with A worm drive circular saw
and A metal cutting blade or bite the bullet and pick up A real chop
saw. I bought one at an auction last week to carry in the work truck for
35 bucks. It's only 12 inch but like new as the guy that owned it used
it to cut plastic drain tile.Not much wear on it from that stuff and I
got 4 plastic cutting blades with it.

Harbor Freight sells a little conversion kit for doing this. However,
people who have tried them say they will not produce an accurate cut.
thanks for all the posts.
can someone explain to me how getting another power tool is cheap? I am
cramped on space, I'd only need to used the converted angle iron as a
chop saw maybe 4 times a YEAR. that woudl come to what, $25 per use if
i only use it for one year?
anyway, now that i know it is possible, i'll give it a go. once it cuts
moderately square, thats all i'd need, and only 4 times a year at that
(at the most)
