Questions & Answers
What is the actual spindle thread size?
The one I have has 3/8-24 threads.

can you use a ceramic flap disc on your 4 inch grinder. I think the disc are 4 and a half
Due to the size of the guard on this unit you can only run 4 inch discs.

How do I order new Grinding Wheels for the Rockwood 4" Air Grinder item #31818? Can I order them thru Eastwood? Thank you
Currently we do not have the grinding wheels for sale but these should be very easy to source locally as they are 4” diameter, 10,000 RPM with an Arbor Diameter of 5/8”
