BF901X = 3M Unitized Buffing Wheel 3" x 1/2"

Unitized wheels are long-lasting wheels that feature an open web design that makes the buff "springy" thus resistant to pressure. Undercutting and gouging are eliminated. The abrasive impregnated buffs are excellent for producing satin finishes on precious and semi-precious metals. The 3" wheels are 1/2" thick and feature a 1/4" hole for threading on to the tapered spindle of a polishing machine. Four different grits are available.
