8" JET commercial Grinder (New) in HS Welding shop.

I have a Baldor, a 1 hp and scored it for 50$ or someone got it for me. I was going to find some wheels but havnt looked and I use a smaller one when I actually use a bench unit which is pretty rare. I had never priced a new one and was actually going to get an 8 inch Jet when someone gave me the one I currently use.

Try McMaster-Carr, not cheap, was paying around $50 ea for a 7" but a good selection & not sourced from a Chinese slave labor camp.

We had a 25 year old 5 HP Baldor grinder in our shop. Often went back to make sure I turned it off. Was so balanced would spin for several minutes before coming to a stop. I inherited a made in USA 6" bench grinder 50 years ago. Rarely use it so store it in a milk crate in my damp unheated garage. When I used it last year noticed the cord was cracked and still did not trip a GFCI receptacle. Sad only one USA company makes bench grinders. One great thing about Sears years ago they stocked replacement parts. I had a $100 Craftsman hand drill that a piece of pop rivet I drilled out entered the drill and cut insulation on a few windings. Called Sears and they apologized because the replacement brushes were on in back order but they I got a new drill winding very cheap and a few days later brushes. Took less then 7 or 8 days.

Good evening,

Just installed power to a new 8" JET Bench grinder 120v 3.5 to 7a . The existing 20a GFI trips when started.

Years ago I had that exact problem with a old grinder started to pop the gfi, I think it was a JET.
I took it apart cleaned with compressed air, and the device that kicks on the start winding "centrifugal switch" if I recall had roasted,
I was able to replace the switch and a cap and it worked, that was a pretty old grinder,
I am not sure how they are made these days
and a new one I'd expect to work or I'd just return it.

Mine never trips any GFCIs

Sorry. Misspelled it. Should be Baldor. Had no idea they were so expensive now. I think mine was about $500.

Baldor quality went down since ABB took over them.

I've had a handful of motors since ABB took over with internal issues first time running them. Particularly in the farm duty motor line.

Can't speak for any QC issues on grinder motors though.

Called JET Tech support and was told that there bench grinders can not be plugged into a GFI.

Love how many manufacturers claim their product can't be used on a GFCI, yet here we are with more and more locations requiring GFCI, sort of making their product sort of useless if they can't design it to have less leakage current.

Bench grinders typically go in garages, service bays, and other similar spaces that have all required GFCI protection on 15 and 20 amp 120 volt receptacles for more than 20 -25 years now. No reason this should be a problem with most power tools. Only other thing might be cheap GFCI that doesn't handle inductive kickback as well as better quality devices, but that is usually a problem when turning off a load.
