HSS-E Spiral point taps Machine taps for deep though hole No coating For hardness steel and high temperature alloys

   the tapping speed has a great influence on chip flow and the life of the tap,it is worthwhile to establish the ideal speed by tapping trials.

   Characteristics of the material,machine and clamping method should be taken into consideration.
