Meta Description: Carl recommends a "Best Buy" industrial quality bench grinder. A Dayton 2LKR9. Why this grinder? Must be 8", Make your own grinder stand. Tool rests & grinding wheels.
I love my new bench grinder! I purchased it in Sept of 2012.
I had to replace a 10 year old Delta 8″ bench grinder that was giving me trouble.
Updated 7/2/2020. After 8 years of frequent use the “stationary switch” inside of my Dayton 2LKR9 grinder wore out. i.e. the switch that cuts out the motor start capacitor after the motor comes up to speed. (Not the main on/off switch). It is the thing that goes “click” after the grinder starts up.
I am happy to report that replacing the switch turned out to be a pleasant experience. Yea, I would have liked to avoid it. But, working on something that was designed to be taken apart and repaired was a real joy.
A new “stationary switch” cost me $41 with shipping on 6/2020. For more info see “Stationary Switch Replacement” below.
After taking the grinder and motor all apart, I known there is no cheap plastic crap inside of this grinder. The bearings, etc are really good quality.
I really wish I did not “smoke” the grinder. I knew there was something wrong with grinder for a few weeks. It did not sound right when it started up. The familiar click was gone or muted. But, I was busy turning! I did not open up the grinder until after I saw smoke. I got away with it. Just melted some coil bindings rather than the actual copper coils. However, I probably shortened the life of the grinder. I feel like an idiot because replacing the failing switch was an easy job.
Note: The main on/off switch failed several years ago. I easily replaced it with one from my local hardware store.
Updated 3/18/2020. I still love this grinder. It is still available from Zoro # G1762144. The price has gone up to $318. I still think that is a great price.
The newer versions of Dayton 2LKR9 grinder are light gray. Rather than dark gray. I changed the photo below to the new color.
If you want a slow speed grinder then I would go with a $125 Rikon 80-805, 1/2 HP, 8” Slow Speed Bench Grinder from Amazon. Or a $245 Rikon 80-809, 1 HP, 8” Slow Speed Bench Grinder from Amazon. But you don’t really need 1 HP.
