An electrical handheld shovel system includes a handheld shovel with an auger bit. The shovel includes a motor configured to rotate the auger bit and a portable power source configured to power the motor. The shovel includes an input/output (I/O) device and a controller to control rotation of the auger bit. The shovel has a handle and a shovel portion. In one example, the power source is integrated into the handle, and in another example, the power source is detachably coupled to the handle. The shovel has a gearbox coupled to the motor. The shovel portion includes a blade positioned proximal to the auger bit to retain debris from the auger bit. The auger bit has a flute that is partially covered by the blade, and the blade defines a discharge opening configured to discharge at least some of the debris.

A frangibility device for creating a preferred breakage plane or weakness within cured columns such as rigid inclusions (RIs) and/or vibratory concrete columns (VCCs) comprises a cutting disc, an elongate strut attached to the center of the disc, and a detachable handle for turning. The disc comprises a thin geometric plate slit from center to periphery, so that a slicing wing can be bent downward at a shallow angle from the slit. The slicing wing advances the cutting disc through the cementious material of the uncured column. When the disc reaches the desired depth, the handle is removed and both disc and strut are left in place during curing.

A hole digger is provided. The hole digger includes a first handle assembly and a second handle assembly. The first handle assembly includes a first grip, a first intermediate portion, and a first blade. The first intermediate portion extends between the first grip and the first blade. The second handle assembly including a second grip, a second intermediate portion, and a second blade. The second intermediate portion extends between the second grip and the second blade. The second handle assembly is pivotally coupled to the first handle assembly such that a front surface of the first blade faces a front surface of the second blade. The first blade is not identical to the second blade. At least one stiffener is coupled to at least one of the first or second blades.

A hole boring device includes a housing including a proximal end, an open distal end, and a bore extending longitudinally from the distal end to the proximal end. An inlet connectable to a pressurized water source is disposed on the proximal end of the housing. A spraying device in fluid communication with the inlet is disposed in the bore and is oriented towards the open distal end of the housing. The spraying device is configured discharge a stream of water passing therethrough so as to form a boring stream configured to bore a hole in a ground surface. In some embodiments, the spraying device is configured to rotatably discharge the pressurized stream of water. A depth collar disposed annularly about the housing defines the depth of the bored hole. A slot disposed along the housing allows debris from the boring process to exit the housing, leaving an empty bored hole.

The present invention is a digging auger. The digging auger comprises a shaft with a proximal end and a distal end. The digging auger also comprises a screw extending from the proximal end to the distal end of the shaft. The digging auger further comprises a paddle attachment adapted to be removably attached at the proximal end of the shaft. The paddle attachment comprises two pieces of rubber strips arranged on opposing sides of the shaft and extending generally radially outwards therefrom.

A yard tool blade is provided with a distal edge to dig a work material, with a surface to support the work material and an adaptor at a proximal end for receipt of a handle. The distal edge is sharpened to an angle within a tolerance of forty to fifty degrees for a reduced thickness to cut the work material. A method for manufacturing the yard tool blade forms a yard tool blade blank. A cutting edge is machined on a distal edge of the yard tool blade blank. The yard tool blade blank is formed into a shaped yard tool blade. The shaped yard tool blade is heat treated after the cutting edge is machined on the distal edge.

A cutting head includes a main body that is attachable to an ice drill shaft at a top side. The main body includes a bottom side that has a bottom peripheral surface. The cutting head includes at least one cutting edge that is disposed on the main body. The cutting edge is configured to perform a cutting operation at the bottom side of the main body. The cutting head includes a cutting rate control pad that is disposed on the bottom side of the main body. The cutting rate control pad extends away from the bottom peripheral surface.

An automated post hole digger for efficient, assisted hole digging includes a base plate having a top side separated from a bottom side forming an inner cavity. A pair of jaws is pivotably coupled to the base plate. A bottom end of each of a pair of handles is coupled to the pair of jaws to move the pair of jaws between an open position and a closed position. A hole saw is coupled to the base plate and comprises a motor, a battery pack, a piston coupled to the motor and extending through the bottom side, and a bit head that is selectively engageable with the piston. The piston is driven by the motor and the bit head is configured to break up hard soil, clay, concrete, and other material. A plurality of controls is coupled to the pair of handles to operate the hole saw.
