  • What buyers say about Forney 72757 Wire Cup Brush, Knotted

    A:

    The biggest problem with this and all brushes that thread onto a 5/8 arbor is that most 15/16ths wrench are too thick to slip in around the nut. I solved the problem by cutting a piece of 1/4" thick 1-1/2" steel bar, cutting a 15/16" slot and welding it to the

    Q:
