The cast-iron base features anti-vibration rubber feet and is equipped with mounting holes for convenient attachment to a workbench or grinder stand.

I've been browsing the used market for a grinder, not entirely sure of what I'm looking for. Most seem to be pretty low power (1/3) HP from like 30 years ago and cost $60-100.

I'll need to sharpen chisels, and it'd be nice to have something to mount a buffing wheel to, as well.

Anyone have experience with this or grinders in general? I know the brand but even just the 5 year warranty seems solid.

You definitely shouldn't be sharpening chisels with a bench grinder...

IMHO, the only time you should put a chisel to a grinder is when it isn't a chisel and you want it to be, it you want it to be something else.

What I mean if course is it's only suitable if you've damaged it so badly you need to grind a new bevel, or to put a bevel on something to use it as a chisel.

For sharpening, I recommend diamond stones like Paul Sellers uses (equiv of 250, 600,1200 grits and final finish on a leather strop with chromium oxide- Google his videos), Norton oil stones, Japanese water stones, or the cheapest which is the "Scary Sharp" method , which is sandpaper on plate glass. There's no sin in using a honing guide.

Grinders are good for shaping cutting edges, but heat thin metal very quickly which will weaken it's edge holding ability. Getting shaving sharp takes a little more finesse.

Plenty of people use wheels for sharpening chisels. This looks like a solid deal on a decent brand. I'd take this all day over a wen.

Of course the next thing you'll be looking at is a cbn wheel! Also very worth it!

If you have all the time in the world then yea going through stone grits can be good and satisfying.... but that isn't going to work when you need quick edges.

Using stones absolutely works quickly once you have initialized the chisel.

The advantage of a slower grind is that less heat is generated, thereby reducing the chance of ruining the temper of a blade.

Also less material removed, which isn't worth nothing I imagine. If you're using lathe tools and just want to touch up your tools then a CBN wheel and a slow speed grinder is probably the best thing I can recommend.
