Special Thread Taps

HSS Special Pitch Taps, up to 1/2 inch

Special Pitch taps for cutting UTS/Imperial/"Inch"/SAE threads.
"Special Pitch" sizes are any Unified Thread Standard sizes that are NOT the "Unified National Course/ Unified National Fine" standards.
High Speed Steel. Ground Thread.

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.

HSS Special Pitch Taps, 1-3/16 to 4 inch

Special Pitch taps for cutting UTS/Imperial/"Inch"/SAE threads.
High Speed Steel. Ground Thread.
'Special Pitch' sizes are any UTS sizes that are NOT the "National Course/ National Fine" standards.

The following larger sizes are usually available as well:
4-1/4"-8 or 12 tpi; 4-1/2"-8 or 12; 4-3/4"-8 or 12; 5"-8 or 12.
Please send us an email for price and availability of these sizes.

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 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.
