It accepts an 11\/16 inch tap and provides a tap entry depth of 1-9\/16 inches, making it suitable for through-hole and blind-hole tapping operations where controlled depth and torque relief are required. The split sleeve design allows the driver to release and reset when the tap meets resistance, protecting both the tap and the workpiece. Licensed machinists and toolroom technicians are the primary users of this driver in production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis tapping driver fits into MT3 taper shank tool holders and is used in metalworking applications on drill presses, knee mills, and similar machine tools. The 1\/4 inch projection and a tap shank diameter of 0.542 inches make it compatible with standard tapping chuck setups. It is suited for repetitive tapping operations in manufacturing, fabrication, and repair environments where consistent thread quality is needed across steel, aluminum, and other machinable materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSplit sleeve mechanism releases under overload to protect tap and workpiece\u003c\/li\u003e\n\u003cli\u003eMT3 taper shank for direct mounting in compatible spindles\u003c\/li\u003e\n\u003cli\u003eAccepts 11\/16 inch tap size\u003c\/li\u003e\n\u003cli\u003eTap entry depth of 1-9\/16 inches for through and blind hole applications\u003c\/li\u003e\n\u003cli\u003eTap shank diameter of 0.542 inches with 0.406 inch tap shank square for positive drive\u003c\/li\u003e\n\u003cli\u003e1\/4 inch projection for close-clearance tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for MT3 taper shank tapping chuck applications on drill presses and milling machines requiring an 11\/16 inch tap driver.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with taper shank tooling. Power down and lock out the machine spindle before seating or removing the MT3 taper shank. Clean the taper bore and shank with a lint-free cloth before insertion to ensure full contact and prevent fretting. Do not use a hammer directly on the driver body; use a proper draw bar or drift to seat and eject the taper.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Size\u003c\/strong\u003e: 11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Entry Depth\u003c\/strong\u003e: 1-9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: MT3 Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Shank Diameter\u003c\/strong\u003e: 0.542 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Shank Square\u003c\/strong\u003e: 0.406 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COLLIS TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 73423\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLLIS TOOL","offers":[{"title":"Default Title","offer_id":67917685227826,"sku":"73423","price":72.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/563b693e5462567177906fb4be3800ac.jpg?v=1791264687","url":"https:\/\/voomisupply.com\/products\/collis-tool-73423-split-sleeve-tapping-driver-mt3","provider":"Voomi Supply","version":"1.0","type":"link"}
