HSS Special Pitch Taps, up to 1/2 inch

HSS Special Pitch Taps, up to 1/2 inch

Follow this link to explore our complete offering of taps, dies, and other threading tools.

To determine the proper drill size for 75% thread on a special pitch tap use the following formula:
Major Diameter minus (0.975 divided by the number of threads-per-inch) = "Theoretical Ideal" Drill Size.
For example, for a 1/4" - 32 tpi tap:
0.250" - (0.975/32) = Drill Size
0.250" - (.0305) = 0.2195"
Now consult a drill chart (there is a "Metalworking Reference" link on the left) and find the nearest size drill that actually exists, etc.
For 0.2195", you'd probably want to choose 7/32" or #2 drill size.
