This tool is used to cut an internal thread in a drilled hole when you need repeatable form and fit. It supports careful thread generation when you do not use a rigid tapping cycle.
Tool alignment at the start influences thread straightness, torque, and final fit. M indicates an ISO metric thread, where you match nominal size and pitch to the mating thread. HSS G indicates a ground high speed steel tool, typically used when you need consistent cutting geometry.
Note For consistent results, deburr the entry and keep the cutting area clean during use.
