It features an MT4 taper shank for direct mounting in milling machines, drill presses, and machining centers equipped with a Morse Taper 4 spindle. The driver accepts a tap shank diameter of 0.896 inches with a square drive of 0.672 inches, and provides a 3\/8 inch projection. Tap entry depth measures 2-9\/64 inches. The split sleeve design allows the tap to float and align with the pre-drilled hole, reducing the risk of tap breakage and thread damage during the tapping operation.\u003c\/p\u003e\n\u003cp\u003eThis tapping driver is suited for production and maintenance machining environments where consistent thread quality is required. It is used in applications that demand accurate thread formation in metal workpieces on vertical or horizontal machining equipment. The MT4 taper shank gives machinists a secure, repeatable connection to the spindle. Typical users include tool and die shops, maintenance machinists, and production machine operators working with larger tap sizes in the 1-1\/8 inch range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT4 taper shank for direct spindle mounting in Morse Taper 4 machines\u003c\/li\u003e\n  \u003cli\u003eAccepts 1-1\/8 inch tap with 0.896 inch tap shank diameter\u003c\/li\u003e\n  \u003cli\u003eTap shank square of 0.672 inches for positive torque transfer\u003c\/li\u003e\n  \u003cli\u003e2-9\/64 inch tap entry depth for proper thread engagement\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch projection keeps tap positioned accurately at the workpiece\u003c\/li\u003e\n  \u003cli\u003eSplit sleeve design helps prevent tap breakage by allowing float and alignment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for MT4 taper shank spindles requiring a split sleeve tapping driver for 1-1\/8 inch taps.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. The machine spindle must be fully stopped and locked out before mounting or removing the taper shank driver.
