Pocket holes can be formed by drilling a series of holes until a pocket hole is created, but pocket hole jigs make the process much quicker and easier. Pocket hole jigs allow the user to drill a hole at an accurate angle to get a good joint.
The pocket holes require two drilling operations to be completed. The first is to counterbore the pocket hole itself, which houses the screw head within the member. This hole is stopped 1 ⁄ 4 in (6.4 mm) or so from the edge of the frame member. The second step is to drill a pilot hole concentric with the pocket hole which extends through the ...
Pocket-hole joinery: A countersunk screw is driven into the joint at an angle. Biscuit: A wooden oval is glued into two corresponding crescent-shaped slots. Floating tenon joint Also known as a loose tenon joint, a type of mortise and tenon joint where both work pieces are mortised to receive a double-ended tenon. Stitch and glue
The correct tool to start a traditionally drilled hole (a hole drilled by a high-speed steel (HSS) twist drill bit) is a spotting drill bit (or a spot drill bit, as they are referenced in the U.S.). The included angle of the spotting drill bit should be the same as, or greater than, the conventional drill bit so that the drill bit will then ...
Drill jigs started falling into disuse with the invention of the jig borer. Since the widespread penetration of the manufacturing industry by CNC machine tools , in which servo controls are capable of moving the tool to the correct location automatically, the need for drill jigs (and for the jobs of the drill press operators who used them) is ...
X= Position of hole or pocket in X axis; Y= Position of hole or pocket in Y axis; R= Z axis start position, also known as the retract plane or "R-plane". P= Dwell time (in milliseconds, where applicable) Q= Depth of each peck (G73, G83) or amount of shift for boring (G76, G87) I= Shift amount in X direction; J= Shift amount in Y direction
