Tap Holders. These collets are stocked in ANSI (USA) and ISO (England) standards. The ANSI inch series tap collets relate to professional taps manufactured in the United States. Metric collets manufactured in the United States have the same shank sizes as those used for the inch series. The metric collets manufactured to the ISO standard have different shank sizes than the ANSI series metric collets. Both styles are stock items ready for immediate delivery.

NOTE: Always check the size of your tap shank and then match it to the shank size in the charts below. Imported metric taps may not have the same shank size as other taps you have been using. The chart on page 37 indicates the different shank sizes for the same metric tap depending on the country of origin.
