Abstract
A liner for a power tool holder has a wall which defines an interior and an exterior periphery. The interior periphery is sized to receive a tool shaft and the exterior periphery is sized to fit within a tool holder. The liner protects the tool shafts from marring, nicking or the like while being frictionally held by the tool holder.
Claims18
A liner for a tool holder, comprising:
- a hollow member having a wall defining an interior periphery and an exterior periphery;
- said interior periphery being sized to receive a tool shaft and said exterior periphery being sized to fit within a tool holder;
- and
- said hollow member protecting the tool from damage such as marring or nicking, said hollow member including two arcuate portions defining an elongated overall cylindrical configuration and said two arcuate portions having a thickness, one arcuate portion having a thickness greater than the other arcuate portion.
