Fixaball UNF 3rd Bottom Machine Hand Taps HSS Quality

For cutting UNF threads in pre-drilled holes, this Fixaball machine/hand tap is supplied in a 3rd/bottom pattern for threading close to the base of a blind hole. Made from HSS, it suits both machine and hand use and should be used with a suitable lubricant to help produce cleaner threads and extend tap life.

The ground cutting edge allows threading where a tapered front edge is not required. This tap is available in a choice of UNF sizes to match the thread form needed for the fastener and application.
