It features an MT4 taper shank for secure mounting in compatible machine spindles and delivers a tap entry depth of 1-3\/4 inches. The 2-3\/8-inch projection positions the tap correctly relative to the workpiece, while the 1-1\/8-inch tap shank diameter and 0.843-inch tap shank square provide a solid, slip-resistant drive connection. This driver is used by machinists and pipe fitters to cut internal pipe threads accurately in metalworking and industrial maintenance environments.\u003c\/p\u003e\u003cp\u003eThis driver is suited for production and maintenance tapping operations where pipe thread accuracy is required. It fits standard MT4 taper spindle machines and accepts pipe taps with a 1-1\/8-inch shank diameter and a 0.843-inch square drive. Typical applications include threading pipe ports in manifolds, fittings, and fabricated assemblies. It is commonly used in machine shops, industrial maintenance settings, and pipe fabrication operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMT4 taper shank mounts directly to compatible machine spindles for rigid, concentric tap alignment\u003c\/li\u003e\n\u003cli\u003e1-3\/4-inch tap entry depth accommodates standard 1-inch pipe tap reach requirements\u003c\/li\u003e\n\u003cli\u003e2-3\/8-inch projection provides proper standoff between spindle nose and workpiece\u003c\/li\u003e\n\u003cli\u003e1-1\/8-inch tap shank diameter and 0.843-inch tap shank square deliver positive rotational drive\u003c\/li\u003e\n\u003cli\u003eDesigned for consistent, repeatable pipe thread cutting in production and maintenance tapping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style driver for use with 1-inch pipe taps featuring a 1-1\/8-inch shank diameter and 0.843-inch tap shank square, mounted in MT4 taper spindle machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or pipe fitters using standard MT4 taper tooling procedures. Power down and lock out the machine spindle before seating or removing the taper shank. Clean the spindle bore and taper shank thoroughly before mounting to ensure proper seating and concentricity.
