Question about Dynamic Drill Doctor Large Chuck, Black, Plastic and Metal
The tool is not too old. Diamond wheel seems to be in good shape but bits won't cut after sharpening. It seems like the bit wasn't in the right position for sharpening and the cut is starting too late.
Sounds like the angles have been cut wrong on the bits or you are drilling too fast

To clean out grit: With the Drill Doctor unplugged, shake accumulated bit grinding dust from behind the Wheel Cover into a disposable container. Remove dust particles around the wheel with a small, dry brush. Dispose of the container and drill bit dust in a safe and environmentally approved manner. With a dry cloth wipe the inside and outside of the Sharpening Port to remove any grinding dust that may have accumulated. A standard 1" vacuum hose works equally well.
