Special Pitch Taps, 9/16 to 1-1/8 inch

HSS Special Pitch Taps, 9/16 to 1-1/8 inch

Special Pitch Thread-Cutting Taps.
For cutting "Special" Unified Thread Standard (a.k.a.: Imperial / "Inch" / SAE) threads.
'Special Pitch' sizes are any UTS sizes that are NOT the "National Course/ National Fine" standards.
High Speed Steel, Ground Thread.
Plug-chamfered taps will be provided where available, but Taper or Bottoming taps may be shipped, depending on our stock.

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.
