HSS Special Pitch Taps, up to 1/2 inch

HSS Special Pitch Taps, up to 1/2 inch

Special Pitch threading taps.
High Speed Steel. Ground Thread.

Follow this link to see the corresponding Dies for these Taps..

Follow this link to see all inch size special thread taps..

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 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.
