It accepts a tap shank diameter of 1.108 inches and a tap shank square of 0.831 inches, with a tap entry depth of 2.25 inches and a projection of 2-15\/16 inches. This driver transfers torque from a taper-shank spindle to the tap, allowing controlled thread cutting in a drill press or milling machine setup. Machinists and tool and die professionals install this driver when production or job-shop work requires repeatable tapping operations with consistent depth control.\u003c\/p\u003e\n\u003cp\u003eThe 70306 is suited for metalworking environments where an MT3-equipped machine spindle is already in use. It is appropriate for both job shop and light production settings where the operator needs a reliable interface between the machine and standard tapping attachments. The driver accommodates the specified tap shank geometry, making it a direct-fit solution for setups that require a taper shank tapping driver at this tap size and entry depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT3 Morse taper shank for direct spindle mounting on compatible machines\u003c\/li\u003e\n  \u003cli\u003eAccepts 1-3\/8 inch tap with 1.108 inch tap shank diameter\u003c\/li\u003e\n  \u003cli\u003eTap shank square of 0.831 inches for positive torque engagement\u003c\/li\u003e\n  \u003cli\u003e2.25 inch tap entry depth for controlled thread cutting depth\u003c\/li\u003e\n  \u003cli\u003e2-15\/16 inch projection from spindle face to tap chuck interface\u003c\/li\u003e\n  \u003cli\u003eStandard tapping driver configuration for straightforward installation and tap changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment tapping driver for machine spindles with an MT3 Morse taper and applications requiring a 1-3\/8 inch tap interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Power off and lock out the machine before mounting or removing the taper shank driver from the spindle. Clean the MT3 taper bore and shank mating surfaces before seating to ensure full contact and prevent fretting.
