A drill bit jig includes an elongate member, two jig securing elements and a drill bit guide. The elongate member is hollow so that one or more elongate drill bits may be stored therein. The drill bit guide includes a plurality of through holes where the axes of the through holes are parallel to the axis of the elongate member. Each of the plurality of through holes in the drill bit guide has a different diameter for accommodating drill bits of different thicknesses. The jig securing elements each include an L-shaped bolt and a door protecting material encasing one of the straight sections of the bolt.

A machining tool assembly is provided for machining a blank to form a firearm lower receiver. The assembly includes a pair of side plates positionable on opposed sides of the blank to capture the blank therebetween. A template plate having a template aperture is adapted to be removeably attachable to the side plates. The template aperture is aligned with a top surface of the blank and is adapted for machining a cavity within the blank having a peripheral contour complimentary to a peripheral contour of the template aperture. A centering mechanism is adapted to be removeably attachable to the template plate, with the centering mechanism including an opening aligned with a corresponding void formed on the blank to align the blank with the template plate.

A pocket hole jig in contains: a base, a first fixing assembly, a drilling assembly, and a second fixing assembly. The first fixing assembly and the drilling assembly are arranged on two ends of the base respectively, and an operation space is defined between the first fixing assembly and the drilling assembly of the base so as to accommodate a wooden workpiece. The first fixing assembly includes a push rod, the drilling assembly includes at least one tilted orifice, wherein an inlet segment of the at least one tilted orifice is located on an upper end of the drilling assembly, and an outlet segment of the at least one tilted orifice is located on one side of the drilling assembly. The second fixing assembly is located on one side of the base and includes an abutting seat configured to abut against the wooden workpiece.

A jig for machining firearm frames is described. The jig includes a main body, a top plate, and bushing pockets. Inserts including a rear matched-geometry insert and a front matched-geometry insert are fastened within the main body and positioned to register a location of opposing ends of a blank frame. For example, a beavertail insert shaped complementarily to a proximal end of a firearm, and a rail insert shaped complementarily to a distal end of a firearm may be used as inserts with the jig. A variety of bushing inserts can also be used with the jig to precisely register the locations for desired machining.

A drilling method for forming a plurality of through-holes in a plate member includes: a first step of fixing at least one jig, which has a clearance hole, on a bed of a machine tool; a second step of placing the plate member on the at least one jig and fixing the plate member on the bed; a third step of operating the machine tool so that a leading end portion of a drilling tool of the machine tool is inserted into the clearance hole, and forming a first through-hole at a position of the plate member corresponding to the clearance hole; a fourth step of passing a fixing member through the first through-hole, and fixing the plate member on the at least one jig using the fixing member; and a fifth step of operating the machine tool to form a second through-hole other than the first through-hole.

A jig assembly (10) for location with respect to a first item of furniture, such as a door or drawer front, to which a second item of furniture, such as a handle, is to be secured. The jig assembly (10) comprises a first member in the form of first block (12) and a second member in the form of second block (14), the first block (12) and the second block (14) being configured to be coupled together by a spacer (16). The spacer (16) may comprise, may be identical to, or may correspond to, a handle (18) corresponding to that which is to be secured to the door or drawer front.

Predrill guide tools are disclosed which include a body having a vertical planar member with a front side and a back side, a horizontal planar member with a top side, a bottom side and a tapered end, and an angled drill guide with a front face positioned within a vertical plane; two or more ribs extending from a top side of the horizontal planar member, and one or more keels extending vertically from the bottom side of the horizontal planar member. Methods of using the predrill guide tools to drill holes into deck boards for use with deck clips are also disclosed.

An construction tool apparatus for facilitating the task of joining framing together includes a includes a template having a peripheral wall arranged about a longitudinal plane and with an internal chamber for reception of a section of a construction framing member of predetermined shape, a first guide defining a first guide throughbore extending along a first axis which is arranged at a first oblique angle with respect to the longitudinal plane and a second guide defining a second guide throughbore extending along a second axis which is arranged at a second oblique angle with respect to the longitudinal plane. The first and second throughbores are adapted for reception of a drill to form first and second pilot holes in the section of the framing member. The first and second oblique angles each range from about 50 to 58 degrees relative to the longitudinal plane. In one embodiment, the first and second oblique angles are substantially equivalent.

A pocket hole jig includes a body with a base surface positionable against a workpiece, and a drill guide pivotally coupled to the body. The drill guide defines a guide axis such that a drill bit is insertable into the drill guide along the guide axis. The drill guide is pivotable relative to the body to adjust an inclination angle of the guide axis relative to the base surface.

A clutch brake cutter for removing a disk-shaped clutch brake from off an input shaft that couples a truck engine to a transmission includes one or more cutting tools and employs a method of clamping and axially compressing a solid or multilayer clutch brake during the cutting operation. In some examples, the clutch brake cutter first guides a drill bit radially from an outer peripheral edge to an inner peripheral edge of the clutch brake. The resulting hole has a diameter that is less than the disk thickness of the clutch brake. Next, the clutch brake cutter guides a chisel lengthwise through the predrilled hole to split the hole open. The drilling and chiseling operation is repeated at an opposite location on the clutch brake to separate the clutch into at least two pieces that can be readily removed from the input shaft without having to first remove the transmission.
