Abstract:  
Our invention relates broadly to rotary wiping tools and more specifically to rotary-buffing tools of the type used in the reconditioning of worn engine cylinders. An important object of our invention is the provision of a tool in which the worn wiping elements can be readily replaced and renewed in a permanent rotary head. Another object of our invention is the provision of a rotary head having novel anchoring channels for the wiping elements together with novel cooperating anchors for the replaceable wiping elements. Another important object of our invention is the provision of resilient reinforcing means for the replaceable wiping elements.
