The invention involves an apparatus, comprising a template body 101 with a guide portion 110 wherein the guide portion 110 includes upper 111 and lower 112 guide portions, and a guide portion slot 113. The template body 101 includes a first and second countersink guide channels. The apparatus includes a first spacer coupled to the guide portion slot 113 in a repeatably removeable manner.

An auto-adjusting pocket hole jig docking station including a housing and an adjustment mechanism. The adjustment mechanism carried by the housing and including a first rack and a second rack reciprocally movable between raised and lowered positions, relative the body. A double pinion gear is rotatably carried by the housing with a first gear in meshing engagement with the first rack and a second gear in meshing engagement with the second rack. The first gear and the second gear having a rotational ratio therebetween wherein movement of one of the first rack and the second rack moves the other of the first rack and the second rack a distance proportional to the rotational ratio.

An apparatus for punching an anchor bolt insertion hole is disclosed. The apparatus enables punching work for forming the anchor bolt insertion hole, of which the bottom side is wider than an inlet, on a panel surface for constructing a concrete structure to be performed regardless of the skill of a worker. During operation, the apparatus provides the movement direction of a hammer drill into the vertical direction and the inclination direction so as to enable precise punching work, and doubly arranges springs, which are elastic devices for adjusting the movement range of the hammer drill, so as to uniformly maintain the angle and size for cutting a wall such that a cross-sectional diameter is large at a portion adjacent to the bottom of the anchor bolt insertion hole.

A centering device for guiding a fastener or a drill during a setting operation. The centering device is arranged in or at a passage opening of a component, which forms a fastening point. The component can be a substantially flat metal part, in particular a lug or bracket for a faade element. The centering device is arranged at the plane of the back of the passage opening and includes a collar and connecting elements between the collar and the edge of the passage opening. The collar has a substantially flat to bead-like annular shape and is formed in the component. The central opening of the collar forms a centering seat for a fastener or drill during setting. A fastening arrangement has a component, centering device and matching screw. The screw forms a form fit via its lower head portion in the passage opening after completion of the setting process.

A cutting guide apparatus for guiding placement of bore holes in a door may include an engagement interface and a backset assembly. The engagement interface may be configured to retain the apparatus proximate to an edge of a door. The engagement interface may include a handle hole guide structure and an edge bore guide structure. The backset assembly may be operably coupled to the engagement interface to enable an amount of backset from the edge of the door to a center of the handle hole guide structure to be adjusted. The engagement interface may include a first leg configured to be disposed along a first face of the door, and a second leg configured to be disposed along a second face of the door. The backset assembly may be configured to engage the edge of the door at a variable location between the first and second legs.

A pocket hole jig includes: a body; an actuator moveably coupled to the body; a clamp head moveable between an open state and a closed state, wherein the clamp head selectively secures a workpiece in a clamping region of the pocket hole jig in the closed state; a spring biasing the clamp head to the open state; a drill guide defining a guide axis for a drill bit; and a linkage extending between the actuator and each of the clamp head and the drill guide to move the clamp head between the open and closed states in response to movement of the actuator.

A positioning device for drilling including a positioning base which is provided with a positioning through hole, and a plurality of clamping assemblies which are provided on the positioning base and circumferentially spaced round a central axis a, as center, of the positioning through hole. Each of the clamping assemblies includes an abutting part having an adjustable distance from a central axis of the positioning through hole.

A hole-drilling guiding device includes a base including a bottom seat and two vertical seats extending upward from the bottom seat. The bottom seat has a bottom surface including two coupling bar fixation sections. Two rotary seats are respectively and rotatably coupled to the vertical seats. A rotary knob is coupled to one of the rotary seats. A handle is coupled to the other one of the rotary seats. Two guide posts are received through the rotary seats. A chuck seat is fit to the guide posts. A chuck is rotatably mounted to the chuck seat. Two coupling bars are provided, each including a bar body, a rotation driving section at one end of the bar body, and a first fixation section at an opposite end of the bar body. The first fixation sections of the coupling bars are selectively and removably coupled to the coupling bar fixation sections of.

A pocket hole jig includes a body with a base surface positionable against a workpiece and a recess extending into the body from the base surface, a gimbal pivotally coupled to the body and including a gimbal aperture extending therethrough, and a drill guide received by the gimbal aperture and including a drill guide aperture extending therethrough. The drill guide aperture defines a guide axis for a drill bit such that the drill bit is insertable into the drill guide aperture along the guide axis. The drill guide is pivotable with the gimbal relative to the body to adjust an inclination angle of the guide axis relative to the base surface, and the drill guide is movable along the gimbal aperture.

A pocket hole jig that includes a stop collar alignment cavity for properly axially aligning a stop collar along a drill bit is provided. The pocket hole jig may be part of a kit that also includes the drill bit and a stop collar. Methods of using the pocket hole jig and pocket hole jig kit are provided.
