A drilling tool includes: a drive source; a bit attachment portion to which an end bit is attachable; a power transmission portion configured to apply a motive force to the end bit attached to the bit attachment portion; an operation portion switchable between an ON-state and an OFF-state by a manual operation and configured to receive a setting operation for setting a stop condition; and a controller configured to set the stop condition based on the setting operation, and to start driving of the drive source in response to a first switching operation for switching the operation portion from the OFF-state to the ON-state. In a state where the stop condition is set, even when the operation portion is in the ON-state, the controller stops driving of the drive source in response to the stop condition being met while the drive source is being driven.

A tool device has a deceleration unit, a tip tool, and a reaction bar. The deceleration unit increases a torque that is input to the deceleration unit. The tip tool is rotated when receiving a motive force from the deceleration unit. The reaction bar is fixed to the deceleration unit. An external force can be made to act on the reaction bar to receive a reaction force that is generated during rotation of the tip tool.

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.

An apparatus for the formation of a channel in a workpiece located at a first face of a base of the body of the apparatus, the channel formed by a drill assembly of the apparatus connected to drive means located on a second opposing side of the base, the drill assembly and drive means mounted so as to be movable in a guided manner with respect to the base. The movement is achieved by manual movement of a gripping means of an actuation means of the apparatus with respect to the base, so as to cause one or more flexible connecting members of the actuation means which are positioned intermediate the gripping means and drill assembly to move and advance the drill assembly towards the workpiece. The channel is formed in accurate manner which then allows the same to receive securing means typically to allow a joint between first and second workpieces to be accurately formed.

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.
