6pcs HSS Drill Tap Bits

Drill tap bits increase efficiency of operation by allowing for drilling and tapping to be accomplished in a single pass. These HSS drill and tap bits are great tools used to create screw threads, to cut or form the female portion of the mating pair. They are used on a machine to do the tapping, such as a lathe. Machine tapping with these taps is faster, and generally more accurate because human error is eliminated.
