Abstract

See full text

A unibit re-sharpening device for reconditioning the surface of worn unibits by filing them in a tapered recess. The unibit re-sharpening device comprises a device housing having a tapered recess with a diamond infused file therein, with the file connected to an integrated electric motor and high frequency mechanical vibrator, with an attachable collet for securing a conventional unibit in the tapered recess. In use, a unibit is secured in the collet and the collet is placed in the tapered recess. The power switch is then turned on, causing the motor and vibrator to vibrate the file and resulting in material being cut from the cutting edge or face of the unibit by the vibrating file. While the file is vibrating, a user can rotate the unibit to expose its whole conical surface to the file, thereby sharpening the entire unibit.
