Due to the different relationships between the shape of the cut object and the position of the tapping teeth, when using NC, MC and other specialized tapping machines for tapping teeth,

Usually, the length of a silk tap is not sufficient, so it is necessary to use an extended silk tap.

·Screw tapping accuracy grade: YAMAWA P grade
·Screw tapping material: HSS-E
·Number of teeth in the cutting edge: 5 teeth
·Suitable for cutting materials: carbon steel, alloy steel, copper, aluminum, zinc and other light alloys with tensile strength below 750N/mm2.
