It accepts a tap shank diameter of 0.687 inches and a tap square size of 0.515 inches, providing a secure, repeatable connection between the tapping head and the cutting tool. This adapter is used in CNC machining and tapping operations where tool change speed and tap alignment accuracy are critical. It is installed by machinists and tooling technicians working with compatible NUMERTAP 200 Series tapping heads on vertical or horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for production environments requiring consistent tap engagement on pipe thread forms. The quick-change design reduces changeover time between tap sizes without removing the entire tapping unit from the spindle. With a flange diameter of 1.89 inches and an outside shank diameter of 1.22 inches, the 20-050N fits standard NUMERTAP 200 Series holders used in light to medium-duty tapping applications across general metalworking and industrial machining operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick-change interface for fast tap swaps without full tool removal\u003c\/li\u003e\n  \u003cli\u003eAccepts 1\/2 inch pipe tap size with 0.687 inch tap shank diameter\u003c\/li\u003e\n  \u003cli\u003eTap square size of 0.515 inches for positive drive engagement\u003c\/li\u003e\n  \u003cli\u003eProjection of 0.430 inches for controlled tap reach\u003c\/li\u003e\n  \u003cli\u003eFlange diameter of 1.89 inches for stable seating in NUMERTAP 200 Series holders\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design  -  suitable for external coolant delivery setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the PARLEC NUMERTAP 200 Series tapping system, accommodating Size 2 adapter configurations for 1\/2 inch pipe taps.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with tapping head systems. Ensure the spindle is fully stopped and the machine is in a safe state before changing adapters.
