A grinder for cutting deeper than a rotary tool?
 

I suppose that's a good use for a grinder, when a rotary tool cutoff wheel
won't make it deep enough through the material.

What should I look for, for cutting through tool steel like sockets are
made from?

Thanks.

I need it now, so just ordered a $30 angle grinder and some cutoff
wheels...

PORTER-CABLE PC60TAG 6.0-Amp 4-1/2-Inch Angle Grinder
DEWALT DW8061B5 4-Inch by 0.045-Inch Metal and Stainless Cutting Wheel

Hopefully that will do. Will upgrade later.

Depending on the cut desired, EDM or ultrasonic (impact grinding)
solutions can handle most any hardness of material. If you
just want a slice, there are metal cutting abrasive blades for
table saws or Skilsaws (beware sparks, though).

And in a pinch, people have used copper disks and a slurry of
abrasive/glycerine/water to do the same sort of work. It's
not as fast, though.

I just picked up 1/8" and .045" thick disks. The thin disk is only 4
inches diameter, but I'm going to try sticking it on my miter saw. If it
works, it will be a nice solution. Besides providing a sturdy chopping
motion, the cheap miter saw allows for beveling and angling. I would
just need to spin the material as usual and devise a way to move the
cutting disc slowly through the material. Maybe using a 5/16 inch
threaded rod with a wingnut, attached to the handle.

The miter saw is only 5500 RPM, but that should be enough for now.
Except for the lack of blazing speed, it is much better than an angle
grinder for the task of slicing halfway through a 1 1/4 inch socket. I
will look at other chop saws later, like maybe another inexpensive
miter saw that is faster than 5500 RPM. But this should do for now.
