Not truly a direct answer but doubtful a true stainless, a magnet sticks. My guess same as most wire brushes some sort of coated metal or spring type wire/steel because it holds up to pretty rough use doing a set of 4 old rusted Toyota steel rims. I've had and used it over the past 2-3 years stored in a unheated garage and no rust so possibly knowing this may help you decide.
The width of this product is 4.61 in.
Hi CC10463, This Avanti Pro Wire wheel is meant for metals only.
I don't think it would work very good for that.
I'm sure it will but you better be very careful using it.
Hello tgoody, thank you for your question and interest in Avanti Pro accessories. It really depends on the bench grinder that you have. Most 8" Bench grinders have a 1" arbor and most 6" bench grinders have a 3/4" arbor. However, the 3" wire wheel is not intended for a Bench Grinder, this is a drill mounted wheel. Hope this helps. Thanks.
Hello tgoody, thank you for your question and interest in Avanti Pro wire wheels. The Shaft on the wire wheel is 1/4" in diameter. hope this helps. Thanks!
