Extended Shank Allows Side Loading
A threaded shank on the 3M Roloc + Button passes through the unitized wheel’s 3/8″ center hole and twists into a Roloc + holder. (Note: The Roloc + holder comes in the 3M Roloc+ Button Combination Pack or can be purchased separately). Then, the 3M Roloc + holder (sold separately) can be mounted on the power tool, most commonly on tools featuring a _? collet chuck. The 3M Roloc+ Button has an extended load bearing shank, which provides added bending strength for applications using Unitized Wheels where side loading occurs.
