Notes on Tapping
1. The speeds listed above are a recommendation only, and are based on depth of thread listed, speeds can be adjusted on application.
As a general rule;
-If hole depth required is less than above mentioned = increase speed
-If hole depth required is more than above mentioned = reduce speed
2. Taps must be driven by the square to eliminate slippage, eg, ER-GB collets (square drive).
3. When using spiral flute taps with length compensation tapping attachment, it is recommended to short pitch the feed 95%,
to eliminate tap cutting oversize, eg. M6x1 @ 1000RPM, Feedrate= 950mm/min.
4. Forming taps are suitable for materials with >10% elongation
