It features a tap shank diameter of 0.562 inches and a tap square size of 0.421 inches, providing a secure, positive drive connection to the tap. Through-coolant capability allows coolant to flow directly to the cutting zone, improving tool life and chip evacuation during tapping operations. This adapter is installed by machinists, CNC operators, and toolroom technicians working with tapping heads or quick-change tap holders on machining centers, drill presses, and tapping machines.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for production tapping environments where repeatable tool changes and consistent tap alignment are required. The quick-change interface reduces setup time between tap sizes. With a flange diameter of 1.88 inches, a projection of 0.35 inches, and a tap depth of 1.18 inches, it accommodates standard tap geometry for Size 2 applications in both job shop and production floor settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSize 2 tapping adapter with 0.562-inch tap shank diameter\u003c\/li\u003e\n  \u003cli\u003eTap square size of 0.421 inches for positive drive engagement\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design directs coolant to the cutting zone\u003c\/li\u003e\n  \u003cli\u003eQuick-change compatible for fast, repeatable tool changes\u003c\/li\u003e\n  \u003cli\u003eFlange diameter of 1.88 inches for stable seating in the holder\u003c\/li\u003e\n  \u003cli\u003eTap depth of 1.18 inches accommodates standard tap shanks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for quick-change tapping systems accepting Size 2 tapping adapters with a 0.562-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians.
