The drill guide snugly fits in the hinge countersink, ensuring perfectly centered pilot hole.

Industrial quality taper point drill manufactured to ANSI standards.Countersinks made from top quality steel and hardened for extended tool life.Countersink has a 4 flute design for smooth, clean holes that do not require sanding.Taper drill bit is adjustable to match length of screw and is held with 1 or 2 hex set screw.  Wood Pre-Drilled Insty-Drive 4 Flute Countersink With High Speed Steel Tapered Drill Wood Fastened.Screw Hidden With Wood Plug1) Select a wood screw size best suited for the project at hand. When selecting screw length, keep in mind that 1/3 of the total length of the screw should be in the piece(s) of wood being attached, and 2/3 should be in the piece of wood to which it is being attached. 2) Use recommended size Taper Drill and Countersink combination (see chart) to pre-drill pilot hole, countersink and counterbore for the screw size of your choice. Position the countersink on the tapered drill so that the point end of the drill extends from the countersink the same distance as the length of the wood screw measured from the head. The locking set screw should be positioned to lock into the flute of the tapered drill. Use the recommended Stop Collar (see chart) if needed to control the depth of the counterbore. Mount the Stop Collar on the Countersink and tighten with set screws.3) Use recommended size (see chart) Plug Cutter to cut tapered plugs to fit over the screw head if the screw is counterbored below the surface of the wood. Plugs can be broken out of the wood with a screwdriver, or the wood can be cut to release the plugs. 4) Attach two pieces of wood by driving screw into pre-drilled hole. Insert wood plug over screw head using a small amount of wood glue. Sand off wood plug flush with surface.
