Abstract
A hand operated auger may include a powerhead, a handle frame, and a drill bit, the drill bit extending along and rotatable about a longitudinal axis. The drill bit may be selectively operable in a normal mode and a breaker mode. The auger may further include an extension shaft disposed between the powerhead and the drill bit, wherein the drill bit is movable along the longitudinal axis relative to the extension shaft. The auger may further include a fluid reservoir and a fluid line. The auger may further include a gyroscope. The auger may further include a roller. The auger may further includes a depth gauge. An auger assembly may include an auger and a removable fixture.
Claims18
An auger, comprising:
- a powerhead;
- a handle frame;
- a drill bit, the drill bit extending along and rotatable about a longitudinal axis, wherein the drill bit is selectively operable in a normal mode and a breaker mode;
- an extension shaft disposed between the powerhead and the drill bit, wherein the drill bit is movable along the longitudinal axis relative to the extension shaft and selectively fixable at a plurality of positions along the extension shaft;
- and
- a sensor which can detect when the breaker mode is necessary, and wherein the drill bit is automatically operable in the breaker mode when the sensor detects that the breaker mode is necessary;
- wherein the sensor detects when the breaker mode is necessary based on a decrease in drill bit rotational velocity;
- and
- wherein the drill bit is translatable along the longitudinal axis in a reciprocating motion relative to the powerhead and the handle frame in the breaker mode.
A hand-held auger, comprising:
- a powerhead;
- at least one battery in communication with the powerhead for selectively operating the powerhead;
- a handle frame, wherein the handle frame comprises a bottom frame and two side frames, and wherein a handle grip is mounted to each of the two side frames;
- a drill bit, the drill bit extending along and rotatable about a longitudinal axis, wherein the drill bit is selectively operable in a normal mode and a breaker mode;
- an extension shaft disposed between the powerhead and the drill bit, wherein the drill bit is movable along the longitudinal axis relative to the extension shaft and selectively fixable at a plurality of positions along the extension shaft;
- and
- a sensor which can detect when the breaker mode is necessary, and wherein the drill bit is automatically operable in the breaker mode when the sensor detects that the breaker mode is necessary;
- wherein the sensor detects when the breaker mode is necessary based on a decrease in drill bit rotational velocity;
- and
- wherein the drill bit is translatable along the longitudinal axis in a reciprocating motion relative to the powerhead and the handle frame in the breaker mode.
