bench grinders

My grinding wheels wore out, and I'm having trouble finding replacements of the right size. Now I discover that bench grinders are inexpensive, so fine, I'll buy a new one. How do I choose one? I assume the cheapest is probably not the best value.

Black and Decker makes a very good line of homeowner tools at good prices. Practically all of my power tools newer than 10 years are of that line.They perform better than their pricepoint in my opinion. Another option is go to Amazon and read reviews of different grinders/

My Baldor 613 (very similar to this Baldor 612) is an excellent tool and has been providing years of problem-free service.

I have a good one, & a cheap one.

Cheap is OK for moderate use. Look for one with OK tool rests.

Why can't you get wheels? Pretty standard sizes.

So much depends on how much you use the grinder. If you used it daily, especially if your income depends on it. I'd get a professional/commercial model that will likely last you the rest of your life. You might look for a nice used one.

But if you only use a grinder once in a long while, like I do, then a Harbor Freight, Rural King, or similar one will probably do anything and everything you need it to do for a very long time.

I have one of the Harbor Freight combo grinder/buffers. The motor isn't as powerful, so you can't reef down hard into a grind, but it does the job of both grinding and buffing nicely. Its a good deal with the 20% coupon

I keep my eyes open for good American made grinders (Baldor,etc). The older the better.

You can always bush wheels to different arbor diameters.

That's extremely helpful. I bought a new wheel, and the hole for the spindle is too big.

I will keep my eyes open for bench grinders on craigslist. Used tools are often a good value. That's how I got my bench vise. But I had to misspell it in my search terms.

Ooh, I found this one. It's more expensive than some others, but it looks really sturdy.

https://hudsonvalley.craigslist.org/...572220158.html

Homeowners use only, excellent for lawnmower blades. Moving to an apartment an this along with other items will not be needed. Very good condition . Original grinding wheels,limited wear.

That delta is probably an import. 1/2 HP is pretty small, but it depends on the quality of the motor.

The plastic spark protectors look good, although the left one looks out of alignment.

Probably not a bad grinder, and better than HF. But there are better ones out there somewhere.

In the US the supermarkets sell food, not bench grinders. France sounds much nicer...

My Baldor was made in the US.

I think Baldor and Dayton still make motors and grinders in the USA. Not necessarily cheap.

Grizzly and Jet should offer reasonably good quality for imports.

Probably other former US brands that now produce overseas are OK.

Expect to stop the wheel of many smaller grinders when doing heavy grinding or sharpening. Also heat issues.

Super light duty grinders have their place. I have a former HD saw sharpener with a diamond wheel mounted that works well for fine grinding and carving/sharpening lathe bits.

If hand-held is an acceptable alternative to a bench grinder, then my DeWalt DWE4214 4½" Small Angle Grinder is a VERY handy tool.

Unless you're going to be using it all day, every day, whatever bench grinder fits your space and budget is the one for you. I only use mine sparingly-- a few times a week-- so the ultra-cheap Central Machinery grinder I got at Harbor Freight has been soldiering on for about 15 years. And it was about $30.

This Baldor Grinder Catalog shows they offer an "E" version of their grinders w/ a dust extraction exhaust port, plus they offer a dust collection system, that all look to control the worst part about grinding, the horrible dirty mess that gets everywhere,

An older Delta is easy to acquire, and they suffice quite well for bicycle use. Flea markets are likely targets for them.

I will say, though (as another poster already did) that arbor adaptors are readily available, both inset bushings as well as arbor plates to support various sized discs.

Grainger/McMaster Carr both carry a huge variety of wheels, and while they aren't as cheap, they will sell to the public, and are concentrated in one place.

Again, you can buy bushings that adapt your wheel to your spindle. See here: https://www.amazon.com/Reducing-Bush.../dp/B01ED30XRY

I have several grinders and buffers (PITA to be changing wheels all the time, you know)

Among them is that identical model Delta 8" one -
I bought it new, maybe 20 - 25 years ago, and have used it regularly ever since - I believe it is Taiwan made.
With good, dressed, wheels it's been a really smooth, reliable machine. It's not a Baldor, but pretty decent
You might want to check it out, if possible, assuming an OK price

Yes, I understood, and I'm glad to know it. I can use the wheel I just bought for my current crappy grinder, once I get one of these bushings.

These are my thoughts exactly. In my lifetime I've been a professional aircraft mechanic, and I'm a second-generation machinist. In both occupations, you buy the cheapest tool that will work and gauge your expenditures on what is most important. Having the best of everything may limit your ability to actually HAVE everything that you need. I buy Harbor Freight stuff now because I have found their tools to be serviceable, their return policy is solid and their customer service is great. I used to have a lot of high quality stuff, but I sold it and got lesser stuff. Why? Because I didnt need it. Its like having a diamond-studded pair of tweezers to pluck your nose hairs, when a cheapie will work as long and as hard.
