A soil boring device and a kit including the same are disclosed herein. The soil boring device includes an elongate tubular body portion; at least one fin member configured to loosen soil when the soil boring device is rotated by a user; at least one handle portion extending outwardly from the elongate tubular body portion; and a water connection subassembly coupled to the elongate tubular body portion. The soil boring device is configured to discharge water from the water outlet of the elongate tubular body portion so as to moisten soil adjacent to the soil boring device, thereby facilitating the forming of the hole in the ground by allowing the soil to be more easily loosened by the at least one fin member. The soil boring device may be provided in conjunction with a soil boring kit that may further include a vacuum collar and a vacuum wand.

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.

A swinging device for spectacle blinds where the swinging device includes a case having a pair of side members connected to a bottom member and first and second shafts rotatably connected to the case. A first gear mounted on the first shaft engages a second gear mounted on the second shaft. A drive handle assembly is connected to the first shaft to impart rotation of the first shaft. A spectacle blind holder is mounted on an end of the second shaft. The spectacle blind holder is arranged and designed to securely hold the spectacle blind. A base assembly has an upper portion connected to the case and a lower portion for mounting to piping.

An arrangement for feeding at least a part of a drilling machine in at least a first direction. A drilling system and a method are provided. The arrangement includes a first end portion, a second end portion, an outer cylinder, a piston and a piston rod. The piston and the piston rod are displaceably arranged in the outer cylinder such that the piston and the piston rod, the outer cylinder and the end portions delimits a first chamber and a second chamber for a pressure medium in the outer cylinder on a respective side of the piston. A valve is connected to the first chamber for reducing the pressure medium in the first chamber. The valve is arranged to be opened at an increased pressure in the second chamber.

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.

The disclosure provides an electric drill comprising: a housing; a motor for driving the electric drill to work; an output assembly for outputting the power of the motor; a first brake assembly including a driving disc and a driven disc respectively arranged on the transmission shaft and the output shaft, the driving disc being meshed with the driven disc to transmit power in a non-braking state, and the driving disc and the driven disc being displaced in the axial direction to be separated from each other in a braking state to stop transmitting power; and a second brake assembly including a mass block and a micro switch connected with the motor, and in a braking state, the mass block displacing and triggering the micro switch to stop the motor.

A hole is formed in a drill target with improved workability. An electric work machine includes a motor, a motor housing accommodating the motor, a handle housing including a grip including a trigger switch operable to activate the motor, a reducer, a gear housing accommodating the reducer, a rotation output unit protruding frontward from the gear housing and rotatable under a rotational force transmitted from the motor through the reducer with a drill bit being attached to the rotation output unit, and a handle fastened to the gear housing and at least partially located laterally from the gear housing.

A system includes a utility chassis for use with rock drills for automatic and safe drilling of target surfaces. The utility chassis has a lightweight vertical frame member with an overall center of gravity that allows for manual lift handles to be arrayed about the center of gravity for easy loading and unloading onto transportation vehicles without the need for separate heavy machinery. The utility chassis incorporates a spring-centered closed position valve for drill rotation and a three-way spring-centered retract with two open feed positions valve for increased safety. A hinged drill rod guide cap is incorporated into the drill rod guide for quick removal of the chassis from lodged or broken drill rods. The chassis is lighter, more ergonomic, and safer than prior art chasses.

A drill assembly attachment having a handle, a drill mount, and a throttle. The throttle may have a first portion and a second portion rotationally engaged with the first portion such that the second portion is rotationally actuated in response to linear actuation of the first portion of the throttle. The throttle is positioned with respect to the drill mount and the handle such that the first portion may be linearly actuated by a user with a hand grasping the handle. The drill assembly attachment receives a drill assembly such that the throttle adjustably engages a trigger of the drill assembly. The drill assembly attachment or the drill assembly receives an auger or other tool and the drill assembly attachment with the drill assembly and auger or other tool is used in a method of rotating the auger or other tool.

Embodiments provide a well-drilling apparatus and a method of use.
