1 KH-A-NL Quick Change Stub Tapper Applications Designed for use on KH-A spindle. Spindle Feed: All kinds of feed styles.for spindle feed other than pitch feed, use KH-A-NL in a condition where the tension feature always works a little. In this case, the length adjustment should be retained less than half. Feature Small projection length. Stable tapping. Projection length is adjustable Length compensation. Quick change (Sold separately) For capable tap sizes, please refer to P chart.
