The split sleeve design provides positive drive while allowing the tap to float axially, which helps reduce tap breakage during threading operations. Key dimensional specs include a 1 inch tap entry depth, a 3\/16 inch projection, a 0.318 inch tap shank diameter, and a 0.238 inch tap shank square. This driver is used by machinists and tool and die trades working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis tapping driver is suited for light-duty tapping applications on drill presses, milling machines, and similar machine tools where an MT1 taper spindle is present. The 5\/16 inch tap capacity makes it appropriate for threading operations in mild steel, aluminum, and similar machinable materials in both job-shop and production settings. It is sold individually and intended for professional machine tool use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT1 taper shank mounts directly into standard MT1 spindles without adapters\u003c\/li\u003e\n  \u003cli\u003eSplit sleeve drive mechanism provides positive torque transfer while allowing axial float\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch tap capacity covers a common range of threading operations\u003c\/li\u003e\n  \u003cli\u003e1 inch tap entry depth accommodates standard tap shank lengths\u003c\/li\u003e\n  \u003cli\u003e0.238 inch tap shank square provides secure, slip-resistant tap engagement\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch projection keeps the tap close to the driver for rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style tapping driver for machine tool spindles with an MT1 Morse taper, accepting 5\/16 inch taps with a 0.318 inch shank diameter and 0.238 inch shank square.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or tool room technicians. Ensure the machine spindle is fully powered down and locked out before seating or removing the MT1 taper shank.
