Abstract: Disclosed is a frame system for displaying an item. The frame system includes a panel, a panel cover, a central viewing portion and a back sheet. The panel includes an inner periphery and an outer periphery. The inner periphery defines the central viewing portion. The panel cover may be disposed on a rear face of the panel and removably secured thereon by a first adhesive. A portion of a rear face of the central viewing portion in proximity to the inner periphery may be coated with a second adhesive. The back sheet may be disposed on a rear face of the central viewing portion and removably secured thereon by the second adhesive. Removal of the back sheet enables the item to secure to a rear face of the central viewing potion and removal of the panel cover enables in detachably mounting the frame system with the item on a surface.

Abstract: A channel cutting tool may include an arbor that connects to a rotating spindle of a machining tool or a similar spinning part of a machining tool. Two slot cutting blades may be fixedly mounted to the arbor. An inner washer may be fixedly mounted on the arbor between the cutting blades and establish the blade spacing. An outer washer may be rotationally mounted to the inner washer with a smaller thickness to facilitate rotation relative to the two cutting blades. The arbor rotates about a longitudinal rotation axis, which also may be the rotation axis for the cutting blades, the inner washer, and the outer washer. The outer washer functions as a depth-limiting safeguard for the channel cutting tool.
