Provided herein is an electric powered digging apparatus comprising: a powerhead, the power head comprises a motor and a gearbox; a handle frame, the powerhead is mounted onto the handle frame; and a drill bit, the drill bit is driven by the motor to rotate around a longitudinal axis, the electric power digging apparatus further comprises: a first safety mechanism, wherein the first safety mechanism reduces torque output to the drill bit when the powerhead spins around the longitudinal axis for an angle larger than a first threshold, and a second safety mechanism, wherein the second safety mechanism reduces torque output to the drill bit when the powerhead spins around the longitudinal drive axis at an angular speed larger than a second threshold FIG. 1

A method for creating a weep hole is disclosed. The weep hole is drilled in an uncured, concrete, hollow core structural component having one or more external surfaces and one or more internal surfaces. The weep hole is drilled using a drilling apparatus comprising a drill, a rotating drill bit with an internal fluid passageway, a power source, and a pressurized fluid source. Loose, uncured concrete material deposited near the weep hole on the one or more internal surface as a result of drilling the weep hole is removed by releasing pressurized fluid which flows from the pressurized fluid source, through the drill and the rotating drill bit.

A vibration damping device for use with a downhole tool having a tool axis may comprise a body coupled to a drill string component. The body may include a longitudinal bore therethrough and at least one lateral bore, the lateral bore having a bore opening and an end wall; an inertial mass slidably disposed in the lateral bore; and a cap mechanically coupled to the lateral bore. The lateral bore may be orthogonal to a radius of the body and may lie in a plane normal to the tool axis. The body may include a plurality of lateral bores, which may be in a co-planar arrangement. Each lateral bore may be blind hole positioned in the body so that it does not intersect the longitudinal bore or another lateral bore. A cap may enclose a lateral bore and fluid may be contained in the bore by the cap.

An earth breaking implement attachment includes a hydraulic pole ram capable of having a plurality of attachments secured to a foot. The attachment is presented in either a first embodiment or a second embodiment. The first attachment is shaped like a shark tooth. The second embodiment has a similar appearance of a screwdriver head.

Hand-operated augers are provided. 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. In some embodiments, the drill bit is selectively operable in a normal mode and a breaker mode. In some embodiments, the auger further includes 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. In some embodiments, the auger further includes a fluid reservoir and a fluid line. In some embodiments, the auger further includes a gyroscope. In some embodiments, the auger further includes a roller. In some embodiments, the auger further includes a depth gauge. In some embodiments, an auger assembly includes an auger and a removable fixture.

A drill bit for chiselling rock includes an impact face at an insertion end of the drill bit, a hollow shank, where a delivery passage is defined within the hollow shank, and a drill head, where the drill head has, at a front end of the drill head, a plurality of cutting faces, an intake opening, and an intake passage. The intake passage connects the intake opening to the delivery passage. The intake opening has a noncircular cross section.

A hand-actuated earth auger of the type used to drill water wells, for taking soil samples, or other similar purposes is disclosed. It consists of a spiral or bladed earth drill, extended with one stem rod consisting of one or more stem segments, and one tee handle mounted on a handle collar. The handle collar can be clamped at any height along the stem rod, while the tee handle can be attached to the handle collar in two configurations, resulting in two different heights of the handle. These features allow the operator to lift the auger out of the ground by doing a seated calf raise in two quick increments, corresponding to the two configurations of the tee handle. It also allows the stem rod to be assembled of fewer, but longer stem segments, thus saving on cost.

A digging apparatus (10, 300) is disclosed. The digging apparatus (10,300) includes a handle assembly (14, 14a, 314), a motor (32), a main switch (22, 322) electrically connected with the motor (32). The main switch (22,322) is movable between a first position in which operation of the motor (32) is allowed and a second position in which operation of the motor (32) is prevented, and a drilling bit (88, 88a, 388) is driven by the motor (32). The drilling bit (88, 88a, 388) has a longitudinal axis (P-P, M-M), and when the switch member (22, 322) is in the first position, the motor (32) is adapted to drive the drilling bit (88, 88a, 388) to rotate about the longitudinal axis (P-P, M-M) in a clockwise direction in response to pushing of the handle assembly (14, 14a, 314) in a direction towards the drilling bit (88, 88a, 388), and the motor (32) is adapted to drive the drilling bit (88, 88a, 388) to rotate about the longitudinal axis (P-P, M-M) in an anti-clockwise direction in response to pulling of the handle assembly (14, 14a, 314) in a direction away from the drilling bit (88, 88a, 388).

The invention provides an electric drill including a bracket with a handle, a drill rod, a motor assembly, and a switch assembly. The switch assembly includes a first micro switch configured to activate or deactivate the motor assembly, a switch pivotably mounted on the handle through a pivot and cooperating with the first micro switch, and a self-locking button engaged with the switch and configured as: when the self-locking button is in a first state, the self-locking button abuts against the switch to prevent the switch from rotating around the pivot; when the self-locking button is in a second state, the self-locking button is disengaged with the switch, and the switch can rotate around the pivot.
