I am looking to buy a bench grinder. Should I get a 6” or an 8”?

6” is fine for grinding woodworking tools.

8” grinders have a higher rim speed. It may
be useful for routine metal grinding in a
metal shop and the wheels last a lot longer,
but for grinding wood tools 6” wheels
last a long time too and run cooler due
to the lower rim speed.

What are you planning to use it for?

Get both… then get a few more… you can never have too many. Kind of like routers :)
(You can find them all the time for cheap on CL)

Cheers,

I have an 8 inch and it works fine. But because I use it to sharpen with a hollow grind, a 6 inch would be a bit better, because the 8 inch wheel leaves a shallower cup on the blades that then need to be re-ground more often. Not really a big deal, but if I were buying new again I’d get a 6 inch.

You need to figure out what want that bench grinder to do! Next comes size of grinder and width of the wheel, horsepower, body style, and cost.
After that buy local and make sure store has a return or refund policy if things go south. Manufactrurers warranties pretty much worthless.

I agree with above ^ it depends a great deal on what you want it for. I’ve settled on a 6” variable speed for most of my tool grinding needs.

I ended up with both: two 6 inch and one 8 inch. None of mine would be called very pricey, or upper level fancy, if you get my drift.

One of the 6” was my first grinder, a Craftsman from circa 1982. The other 6” is a newer Porter Cable variable speed unit from Lowes. The 8” is a Rikon “slow speed” model from Circle Saw in Houston.

All are useful for various tasks, and I am happy to have the options of keeping them set up in different ways most of the time. I usually have a fabric buffing wheels on the old 6”, and or a wire wheel.

The type of wheel used hasn’t been addressed. type of wheel is just as, if not more important than the size or speed of the grinder. Some wheels run cooler; some cut faster; some “load up” and clog. Even the type of material you are grinding is affected by the type of wheel used. The link will give you an idea of what to use. https://www.mcmaster.com/#abrasive-grinding-wheels/=18nkq29, click on “more”.

I have two electrics, 6 & 8 inch, which I use for different things. Smaller one for rough grinding and wire wheel, larger one for chisels. But yeah, agree with Ron about the wheel. In retrospect, I would prefer a belt sander over the 8 inch.

Bench Grinder
First I would like to thank everyone for their input.
I purchased the Delta variable speed 6-inch 23-196 bench grinder.
Out of the box, it started easily with little or no vibration through all ranges.
The stones were fine and had very little run out.
The instructions were of little value but by looking at the various pictures it was not hard to assemble.
I would recommend this product to anyone who is not looking for a large production grinder.

I was looking at that Delta grinder too. Sounds like you made a good purchase.

Have your say...
