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. Clearance 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. The holes made by clearance drills are not to be tapped.

See the chart below for Tap, Die and Drill size reference. For additional information, an explanation of Taps and Dies follows the chart.

Tap and Die sizes follow the same naming standards as machine screws; shank size - threads per inch. For example, a cylinder threaded with a 0-56 tap would hold a size 0, 56 thread-per-inch screw.

Customer Reviews (4.8 / 5 · 5 reviews)

Hazel W. ★★★★★

The carbon steel bit started easily in the brass without any chatter, and the threading came out perfectly aligned. This little tap saved me from ruining a delicate project with cross-threading.

Chloe ★★★★★

This tap cut cleanly through the aluminum block I was testing on, and the carbon steel held up without chipping. It’s a solid tool for making those starter threads in a miniature project.

Nicholas H. ★★★★★

The #30 size is exactly right for M4.0 threads, and the carbon steel held up fine through a few holes in aluminum without dulling. It cut cleanly and didn’t grab or cross-thread, which was my main worry.
