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

    Is it possible to use this to clean moss off a clay tile roof?


    I wouldn't use the Forney wire cup brush for clay or terracotta because it can cause damage to the tiles.


    Is it either carbon steel or stainless steel bristles?


    The Forney 72757 wire cup brush has bristles made of carbon steel.


    I don't know if you need the inner and outer flange nuts for safety or if this cup takes too much space.


    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


    I don't know if I can use this with my drill or if I need other parts.


    I don't think you will be able to without purchasing another "adapter" this threads onto the shaft of the grinder.
