Abstract: An apparatus comprising a cylindrical die holder base containing two recessed compartments, two different abrasive coated sharpen dies, a cylindrical index containing drill bit guide holes used to align drill bit dead center with the sharpening dies, male and female hemispheres on the index and the base to ensure alignment, a spring assembly allowing for separation of index from base while rotating index, a cylindrical safety guard used to cover index holes that are not aligned with sharpening dies, a locking knob used to lock and unlock index to base to allow or disallow rotation, and a radiused handle with a flat bottom used to safely hold drill sharpening device down on a flat surface while in use.

Abstract: A roller assembly for a taping device includes a roller body defining a central bore, a bushing configured to be received within the central bore and rotationally fixed to the roller body, and a shaft configured to be disposed within the central bore. The shaft defines an outer surface that extends through the bushing. The shaft has a boss that extends radially outward from the outer surface. A resistance element is disposable within the central bore is configured to contact the bushing and the boss in a manner providing an amount of rotational resistance between the roller body and the shaft when the roller assembly is in an assembled configuration.
