SPECIAL TAPS NOTES BORING BARS
Unless otherwise specified: Tap sizes 0.395” and smaller have an external center on the thread end REAMERS
Special taps over 1.010” to 1.510” diameter inclusive, having 14 or more (may be removed on bottoming taps). Sizes 0.223” and smaller have
threads per inch or 1.75 millimeter pitch and finer, and sizes over 1.510” an external center on the shank end. Sizes 0.224” thru 0.395” have
diameter with 10 or more threads per inch or 2.5 millimeter pitch and truncated partial cone centers on the shank end (length of cone approx.
finer, are made to general dimensions shown in Table 303 (USCTI). 1/4 of diameter of shank). Sizes over 0.395” have internal centers on both
the thread and shank ends.
Special tap thread limits are determined by using the formulas shown in
Table 331 (USCTI) for Unified Inch Screw Threads and Table 341 (USCTI) For standard thread limits and tolerances for Unified Inch Screw Threads
for Metric M-Profile Screw Threads. see table 327 (USCTI) and for Metric Threads see Table 337 (USCTI).
For eccentricity tolerances of tap elements see Table 317 (USCTI).
