Looking At A Grinder For Sale Baldor

[ebgb68]

I found a Baldor 712e bench grinder for sale locally for 125.00 . Are 7 in wheels that hard to find should I pass on it ? We are doing a Jet order at work and was thinking about ordering a new one from them.

7" Wheels are easy to find. MSC, McMaster Carr even Amazon has them!

Thanks I will have to check them out maybe because I was searching for green wheels they didn't show up ?

Unless you are planning on grinding carbide, you do not need a green wheel. An aluminum oxide (especially the white, a more pure form of AO) wheels will do just fine.

Green wheels are more commonly used on "carbide grinders" where you grind on the face of the wheel, not on the edge. Your grinder is a more common variety.

7" wheels are heavily used for surface grinding. Be careful and look for the correct arbor size, a standard 1.25" arbor hole for a surface grinding wheel won't fit your grinder without a bushing. Your grinder probably takes a 5/8" arbor size wheel, but that's just a guess.

MSC has both aluminum oxide and (green) silicon carbide (various colors) in 7". Most bench grinder wheels come made with 1" bore. Most come with reducing bushings to adapt to smaller shafts. If the wheel doesn't come with reducing bushings they can be purchased separately for about $2 or $3.

Try searching for "Bench & Pedestal Grinding Wheels" on the MSC site:

Enco has a smaller selection:

I do have some bonded carbide cutters I assumed that green wheels worked with all materials ? We carry wheels at work and none of our sources have seven inch wheels . After looking at your links and stopping in at production tool I feel better. Now if I can get a meeting with the seller this weekend.
Thanks guys for your help !

Green wheels are ideally suited for grinding carbide only. You should remove the gross material with an aluminum oxide wheel first, then touch up the carbide on top using the green wheel.
