Just received my weekly AldiMail, and spotted a couple of bench grinders

I do already have a small bench grinder, but could really do with

these

next
to it, suggesting it might fit the bill?

(My current machine has two grinding wheels, which both look like the
right-hand one on the Aldi machine - it's the left-hand wheel which is
presumably of interest.

There's a second machine (a "Bench Grinder and Sander") which has a belt
sander... would that be of any use for my purpose?

The one with the wet wheel is the way to go for chisels etc.

I have one of the Adli ones, good for the money.

The thing to watch out for with "high speed" grinders and also belt
sanders is heating up anything carbon steel (like a chisel) sufficiently
for it to "lose its temper". "Softened" tools can be re-hardened and
tempered, google and (no doubt YouTube) will have plenty of details.

The low speed wet wheel is your best bet, or just an oil or water stone,
or a diamond lap, with a honing jig
