A handheld powered pocket hole drilling system is provided. The system includes a base assembly having a plate. The plate has a drill bit opening extending through the plate. The system includes a drilling assembly and a drill bit connected to the drilling assembly. A drill guide assembly is operably connected to the base assembly and the drilling assembly. The drilling assembly is movable along the drill guide assembly to extend and retract the drill bit through the drill bit opening at an angle. An actuating assembly is operably connected to the drilling assembly. The actuating assembly is configured to move the drilling assembly and drill bit between a retracted position and an extended position. In some arrangements, the actuating assembly moves a drilling assembly and drill bit rearward and downward to the extended position and a handle of the actuating assembly is moved forward and downward.

A self-adjusting pocket hole jig system is presented having a base, an upright assembly operably connected to the base, a clamping assembly, operably connected to the upright assembly, a handle operably connected to the clamping assembly, and a drill guide assembly operably connected to the clamping assembly. The drill guide assembly is configured and arranged to move along the upright assembly between an unclamped position and a clamped position in response to movement of the handle. Movement of the handle simultaneously adjusts the height of the drill guide assembly as well as facilitates clamping of the drill guide assembly for workpieces of various thicknesses.

A drilling tool has a working piece retained by a retainer mounted to a collar. The working piece includes a distal shank and a cutting section and is rotationally fixed relative to the retainer. The retainer may include an engagement protrusion positioned outward of the shank with the protrusion engaging an inner surface of the collar or the collar may include an engagement protrusion with the protrusion engaging an inner surface of the retainer to create a quasi-floating relationship between the retainer and collar. The cutting section may have a distal primary bore cutting sub-section and a proximal counterbore cutting sub-section. The collar includes a lower surface for abutment against a building member during drilling operation to halt axial movement of the tool.

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.

A self-adjusting pocket hole jig system is presented having a base, an upright assembly operably connected to the base, a clamping assembly, operably connected to the upright assembly, a handle operably connected to the clamping assembly, and a drill guide assembly operably connected to the clamping assembly. The drill guide assembly is configured and arranged to move along the upright assembly between an unclamped position and a clamped position in response to movement of the handle. Movement of the handle simultaneously adjusts the height of the drill guide assembly as well as facilitates clamping of the drill guide assembly for workpieces of various thicknesses.

Disclosed are systems and devices for controlling the closing of a door. A head unit is to be installed in a doorjamb, comprising a chamber filled at least in part with a shear thickening fluid. A piston is connected to a cap and configured to exert pressure against the shear thickening fluid in response to a force applied to the cap. The systems and devices provide an adjustable design that resists door slamming and aggressive closure, serving as a safety device as well as noise, damage and pet control around doors (preventing closure if desired). An install kit provides exact location, depth control and guide to place over the head unit to tap it into place with a hammer.

A cutting tool having a shank and a cutting head, wherein the shank carries a depth stop, which limits penetration depth into a workpiece, via at least one pivot bearing, and the depth stop is spring-preloaded away from the cutting head, via the at least one pivot bearing, against a shank-side stop.

An assembly for connecting a wooden sill plate to a concrete foundation slab. The assembly comprises a tapping drill bit and an anchor device. The tapping drill bit comprises a flute having a first flute section and a second flute section, the first flute section being longer and having a smaller diameter than the corresponding dimensions of the second flute section. The anchor device comprises a first anchor section and a second anchor section. The anchor device is structured such that the first anchor section is configured for embedment into the concrete foundation slab, and the second anchor section is configured for embedment in the wooden sill plate. The anchor device thereby delivers an advantageous distribution of shear forces that act on the wooden sill plate in relation to the concrete floor slab.
