Using a 00-09 Clearance Drill, bore a hole in a circle of brass to create a washer that will be placed between the head of the custom screw and the component. The holes made by clearance drills are not to be tapped.Įxample: Use a 00-09 Tap Drill to make a hole in a component which must be joined to another component. TAP DRILLS are bits of a precise size which are used to bore out cylindrical holes in a material or component before creating screw threads with a corresponding-size tap.ĬLEARANCE DRILLS are bits of the correct size for drilling a hole just large enough for the shank of a corresponding-size screw to pass through without touching, such as the hole in a washer. TAPS are used to cut screw threads into the walls of a previously smooth cylindrical hole or bore.ĭIES are used to cut screw threads into the surface of a smooth rod or other cylindrical stock. For example, a cylinder threaded with a 0-56 tap would hold a size 0, 56 thread-per-inch screw. Tap and Die sizes follow the same naming standards as machine screws shank size - threads per inch. For additional information, an explanation of Taps and Dies follows the chart. Taps can also be used to 'chase' clogged threads of debris.

Micro-Mark offers a selection of hard-to-find miniature taps, dies and bits for a wide variety of projects, including model building, clock-making, instrument repair and fabrication, watches, machining and machine work, component assembly, and more.
