Currently there are five standards for Metric taps, each having a different shank size. There are the ANSI (USA), DIN (Europe), ISO (England), JIS (Japanese), and CIC (Chinese) standards. Because of the variety, you need to check the shank diameter of your metric tap. Compare the dimension with the chart on page 37. We stock popular sizes of these different standards, even though they may not be listed. Note: ANSI standard metric taps (the standard common in the United States) cannot be used in the Metric DIN collets shown above.
