A tool bit extractor for removing a drill bit stuck in a workpiece, the tool bit extractor comprising:
- a shaft including a first end, a second end opposite the first end, and a longitudinal axis extending between the first and second ends;
- a cap assembly disposed at the first end of the shaft;
- a bit retention assembly disposed at the second end of the shaft, the bit retention assembly including an opening configured to receive the drill bit;
- and
- a handle including a mass, the handle being moveable relative to the shaft between the first and second ends.
A tool bit extractor for removing a tool accessory stuck in a workpiece, the tool bit extractor comprising:
- a shaft including a first end, a second end opposite the first end, and a longitudinal axis extending between the first and second ends;
- a cap assembly disposed at the first end of the shaft;
- a bit retention assembly disposed at the second end of the shaft, the bit retention assembly configured to receive the tool accessory;
- and
- a mass moveable relative to the shaft between a first position, in which the mass is near the cap assembly, and a second position, in which the mass impacts the cap assembly to facilitate removal of the tool accessory.
A method of removing a tool accessory stuck in a workpiece using a tool bit extractor, the tool bit extractor including a shaft, a cap assembly at one end of the shaft, a bit retention assembly disposed at an opposite end of the shaft, and a mass disposed on the shaft, the method comprising:
- securing the bit retention assembly to the tool accessory;
- positioning the mass near the bit retention assembly;
- rapidly moving the mass in a direction along the shaft and away from the bit retention assembly;
- and
- impacting the mass against the cap assembly, causing the bit retention assembly to impart a pulling force on the stuck drill bit.
