Tap and Drill Organizer (Imperial)

thingiverse

This print is an organizer for imperial tap drills, taps and clearance drills. Tap drill sizes were obtained from Starrett's "Tap Drill Sizes and Decimal Equivalents" chart which can be found with a quick google image search. #8-32 and #8-36 threads require the same tap drill, so I decided to eliminate the tap drill hole on the "Fine" side to hopefully reduce confusion. I used ANSI specified shank diameters to size the holes for taps. I used the "Free Fit" drill sizes from https://littlemachineshop.com/reference/tapdrill.php to size the clearance drill holes. Proper Use: Clearance Drills go in the center row when looking at the object from either the "FINE" or "COARSE" side. When looking at the object from the "COARSE" side, place tap drills in the row of holes closest to the markings (1/2-13, 7/16-14, etc.). Then place the taps in the row of holes between the "COARSE" tap drills and the clearance drills. When looking at the object from the "FINE" side, place tap drills in the row of holes closest to the markings (1/2-20, 7/16-20, etc.). Then place the taps in the row of holes between the "FINE" tap drills and the clearance drills.
