Proudly Manufactured in the USA with globally sourced materials Tapping Formulas and Calculations RPM for UNC/UNF Feed Rate for UNC/UNF Taps RPM for M/MF Taps Feed Rate for M/MF Taps Recommended Feeds and Speeds (SFM) into Material Recommended Feeds and Speeds table below suggests a 'starting point' for selecting the speed to operate the tap. Vertical tapping speeds can be increased, compared to horizontal tapping. Holes, taps with tapered chamfers are able to operateįaster than taps with bottoming chamfers. Speeds must be reduced as length of hole increases. The optimum speed for tapping is highest speed that conditions permit,Ĭonsistent with acceptable tool life. Proper tapping speeds are very important in obtaining efficient tapping results.
