Abstract: A simple inclined-hole drilling jig comprises a jig body having a crossover plane at the bottom to evenly press against the wood workpiece, and a beveled end member at the front concavely disposed with a guiding shaft hole extending downwardly from the beveled end member through the crossover plane. The upper end of guiding shaft hole is configured with a guide bushing for drill bit to pass through. The rear end and side surfaces of jig body are respectively formed with a reference face and sidewalls perpendicular to the crossover plane; the sidewall is at least concavely disposed with a dust guide groove intercrossing the guiding shaft hole and slidingly disposed with a graduated extension board to allow axial displacement and positioning. The end of the extension board is bent to form a retaining end plane parallel to the reference face to extendingly adjust the axle spread of reference face.

Abstract: An improved upright drilling jig comprises two parallel panels parallelly mounted on a leveled base platform, and an inclined-hole drilling jig slidably disposed between the sides of the parallel panels in a manner that it can be vertically adjusted. A sliding saddle is slidably mounted at the top of the inclined-hole drilling jig through two axial bars. The rear side of the drilling jig is concavely constricted to form a bow jumper area and disposed with a discharge concavity in a manner approaching a clamping end plane. The discharge concavity has a chip hole inside that communicates with a guide axle hole. Such arrangement can achieve optimum performance of inclined hole drilling of woodwork.

Abstract: The invention proposes a holding fixture for use in all types of drilling concerning woodworking, comprised of at least one flat worktable having a set of dovetailing portions at the rear end for two flat worktables to dock together horizontally; a longitude-transverse adjustment module vertically arranged on the flat worktable, which secures the guide members for guiding the adjustments of height or latitude during drilling; an angle adjustment module being aligned at the front edge of said flat worktable, which guides the drilling operation on workpieces attached thereof; a height adjustment module vertically arranged at the front edge of flat worktable; a clamp member being secured on the flat worktable for securing workpieces to be worked on; as a result, the holding fixture is suitable for use in guiding the drilling operation on workpiece of all shapes and sizes.

Abstract: A drill guide used in woodworking for preparing pocket joints includes a guide member with a cuboid body. The cuboid body has an inclined plane formed on a front end thereof and a cavity defined in the front end thereof. The cavity has two opposite ends respectively and slantingly extending to the inclined plane and the first datum plane. A guide sleeve is longitudinally and detachably mounted in the front end of the cuboid body and abuts the inclined plane. The guide sleeve extends into the cavity for guiding a drill bit into the cavity and drilling an inclined hole in the workpiece. The cuboid body has a second datum plane formed on a rear end thereof. An axis of the drill bit passes through a central plane of the workpiece on a rear distal edge when the second datum plane aligns with the rear distal edge.
