Part of the NUMERTAP 200 series, this Size 2 adapter features a tap shank diameter of 0.323 inches and a tap square size of 0.242 inches. The quick-change interface allows operators to swap taps rapidly without removing the holder from the spindle, reducing cycle time in high-volume threading operations. It is installed and serviced by machinists and CNC setup technicians in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for production tapping on CNC machining centers and tapping machines where repeatable tap positioning and fast changeover are required. The NUMERTAP 200 series is a widely used quick-change tapping system, and the 20-043 fits within that modular tooling family for 7\/16 inch tap sizes. It is appropriate for ferrous and non-ferrous materials where controlled-depth or through-hole tapping is performed. Coolant-through is not supported on this adapter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick-change interface enables fast tap replacement without removing the holder from the spindle\u003c\/li\u003e\n  \u003cli\u003eTap shank diameter of 0.323 inches and tap square size of 0.242 inches for secure tap engagement\u003c\/li\u003e\n  \u003cli\u003eFlange diameter of 1.890 inches provides stable seating in the toolholder body\u003c\/li\u003e\n  \u003cli\u003eProjection of 0.430 inches allows controlled reach in tight clearance applications\u003c\/li\u003e\n  \u003cli\u003eOutside shank diameter of 1.220 inches for consistent fitment within the NUMERTAP 200 system\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through  -  suitable for applications where flood or external coolant delivery is used\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use within the PARLEC NUMERTAP 200 series quick-change tapping system, accepting 7\/16 inch taps at a Size 2 adapter designation.
