Is 7" an odd size for a grinder?

[Joe McMahon]

I have come across several slow speed Baldor grinders this week. The only thing that bothers me is they are both listed in the catalog as 7" grinders. It appears to me that wheels and accessories come in 8" and 6" mostly. Would better quality wheels be available in 7" size without paying a premium?

Why are 7" produced? Metric?

[Dennis Ford]

7" wheels are readily available from places like McMaster Carr but I am not sure about the grade/grit selection. It would be worth looking into, baldor grinders are as good as they get.

I bought a Baldor 7- inch grinder several years ago simply because it was less expensive than the 8- inch model by quite a bit as I recall. Packard Woodworks stocks wheels in this size. It's a wonderful tool.

I have a seven inch Baldor. If the price is right buy it quickly before someone else does. You can buy 7" Norton 3X wheels from several places including directly from Norton. Jamestown Distributors also carries them and as Charles already said, so does Packard. Terrific grinders those Baldor. Make it better by springing for a set of OneWay balancing hubs. You can't even hear my Baldor run and it is 3450 rpms.

I have the Baldor 7 inch slow speed grinder. I also have CBN wheels which are 8 inches in diameter. The combination of the two is phenomenal.

I also bought a 7" Baldor low speed "slightly" used several years ago, and have not had too much trouble finding wheels such as the Nortons I'm now using. The 8" CBM wheels can be mounted by removing the cast iron shields, and these babies hardly even hum when running.

My old Craftsman is a 7" jobby. Does a good job for me, and I have had no trouble finding wheels.
