These Japanese made Blue Stitched Buffs have 1/2" diameter center holes, not the standard "pin hole center" that all our other buffs come with. That means you can use them on the standard tapered spindle found on 99% of all polishing lathes in jewelry studios.
You need to use an industrial type grinding wheel arbor to use these buffs, of which we only have one option that will work, and it only fits polishing motor shafts of 1/2:" diameter. Our number 147.256, See below.
