A cam lock connected with a fence assembly includes a handle portion, a top carrier and a bottom carrier connected by a threaded shaft. The handle portion and top carrier are positioned above the fence assembly and a work table or surface; wherein the bottom carrier is positioned below the fence assembly and work table or surface. The top carrier and bottom carrier both have a pair of alignment arms with a space positioned therebetween, the alignment arms of the top carrier nest with the alignment arms of the bottom carrier. The handle portion and top carrier both have cam surfaces that engage one another such that when the handle portion is rotated around the axis of the threaded shaft the handle portion is raised or lowered thereby raising or lowering the bottom carrier, thereby locking or unlocking the fence assembly in a quick, durable, easy and accurate manner.

A wood-drill adapter system having a wood-drill adapter assembly. The wood-drill adapter assembly includes a core-bit-blank, an adapter-insert, and a set-screw. The core-bit-blank includes a hollow-tubular body, with the hollow-tubular-body including a hole; and the cap includes a cap-plate, and a threaded-coupler. The wood-drill adapter assembly is useful for allowing a user to use a coring-rotary-tool typically used for concrete drilling/coring to drill a circular-opening in a wooden-material using the wood-boring tool. The adapter-insert includes an upper-disc, a tubular-body, a lower-disc, and a set-screw-receiver. The upper-disc includes an upper-face, a lower-face, an outer-circumference, and an upper-aperture. The lower-disc includes an upper-surface, a lower-surface, an external-circumference, and an internal-circumference. The tubular-body includes an outside-circumference, an inside-circumference, an upper-rim, and a lower-rim.

The current invention provides apparatus and a method for use with a drill bit to form a hole in a workpiece, said apparatus including a clamping means to clamp a workpiece in which the hole is to be formed in position with the apparatus, a drill bit holder assembly and drive means for rotating the drill bit and moving the same into the workpiece so as to drill the hole at a required angle and depth into the workpiece. Typically the depth of the hole is set in relation to the thickness of the workpiece which is clamped in position at that time and the apparatus includes a first part which is held by a first hand of the user and movable by the user with respect to a second part which is held by a second hand of the user and the relative movement is translated into movement of the drill bit holder to move the rotating drill bit into the workpiece.

A pocket hole drilling machine is presented. The pocket hole drilling machine has a cabinet made of a molded unitary monolithic piece. A monolithic top plate is connected to the cabinet with an opening in the middle for an insert plate which is positioned therein. A handle extends above the top plated as does a clamping assembly however actuating mechanics of the device move within the cabinet, thereby improving safety by eliminating pinchpoints. An adjustable fence assembly having cam locks connected thereto is also connected to the top plate. This arrangement provides a low cost, safe and efficient pocket hole drilling machine.
