Great grinder, lousy tool rests
The Delta 8" grinder appears to be well built, comes up to speed quickly and has very little vibration. The wheels that came with mine appear to be straight without wobble.

I haven't used it a lot, but I am already disappointed with the tool rests. They are held in place with plastic wing nuts, and the rests move away from the wheel as you are grinding. I may try to switch to standard nuts to see if it can stay tight.

Grinding wheel wobbles
The grinder seems ok, but one of the grinding wheels it came with was out of round and was useless.

Great product and warranty
Great way to sharpen lawnmower blades. Shipping was a problem, the first one was damaged in shipping and had to be returned for replacement. The second one was OK and was sent out and received in good condition.

Very solid, two heavy grinding wheels, and a speed knob
I'm using this to buff guitar bodies and necks. The 8 inch wheel and variable speed make it great for me. The grinding wheels it comes with are solid. The whole machine us. Should last a long time.

BEST ANSWER: This model is 1/2 hp.
Can this unit except a wire brush instead of honing stone
Dork on Apr 16, 2016
BEST ANSWER: You can get the wire brush to work if you put some spacers or washers on the
shaft to center the brush. It rubs the motor housing.
What size motor is on this grinder
Tooth and nail on Sep 15, 2014
BEST ANSWER: if generally speaking 13amp is one horsepower what is 5 amp
Good afternoon, I recently ordered and got a Delta 23-197 Bench Grinder and along with a wire wheel (DeWalt 4907, 8-inch) to go with it. The wheel does not spin up, hitting within the housing. Please advise, do you have a Delta wire Brush which fits or another suggestion. The Grinder works great just not with the deWalt wire Brush. Does the DeWalt 4906 work? Or maybe I just got a bad one. Will buy another one as long as it works. Thanks for your help, CPO faithful.
