It accepts a tap shank diameter of 1.021 inches and a tap shank square of 0.766 inches, making it compatible with standard tap geometries at that size range. The driver provides 2-19\/64 inches of tap entry depth and a 3\/8 inch projection. At 0.88 pounds, it is a solid, purpose-built tool intended for machinists and tool room technicians performing tapping operations on drill presses, milling machines, or lathes equipped with an MT4 spindle taper.\u003c\/p\u003e\u003cp\u003eThis driver fits into production and job shop environments where repeatable, guided tapping is required. The split sleeve design allows the tap to be held securely while permitting torque to be transmitted consistently. It is suited for operations where a rigid or floating tapping setup is needed on machines with an MT4 taper spindle interface. Typical use cases include threading operations in steel, cast iron, aluminum, and other machinable materials where tap size reaches 1-1\/4 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMT4 taper shank interfaces directly with MT4 spindle machines without an adapter\u003c\/li\u003e\n\u003cli\u003eSplit sleeve design securely retains the tap shank during operation\u003c\/li\u003e\n\u003cli\u003e2-19\/64 inch tap entry depth accommodates standard tap engagement lengths\u003c\/li\u003e\n\u003cli\u003e1.021 inch tap shank diameter and 0.766 inch tap shank square for precise fit\u003c\/li\u003e\n\u003cli\u003e3\/8 inch projection keeps tap positioning consistent\u003c\/li\u003e\n\u003cli\u003eCompact and durable at 0.88 pounds for repeated production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1-1\/4 inch taps with a 1.021 inch shank diameter and 0.766 inch shank square, mounted in machines equipped with an MT4 taper spindle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians familiar with taper shank tooling. Ensure the MT4 taper and spindle socket are clean and free of burrs or debris before seating the driver to achieve proper fit and concentricity. Power down and lock out the machine before inserting or removing taper shank tooling. Verify tap shank dimensions match the driver specifications before use to prevent damage to the tap or driver.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Entry Depth\u003c\/strong\u003e: 2-19\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: MT4 Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Shank Diameter\u003c\/strong\u003e: 1.021 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Shank Square\u003c\/strong\u003e: 0.766 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.88 pounds\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: 74424\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLLIS TOOL","offers":[{"title":"Default Title","offer_id":67906011496754,"sku":"74424","price":96.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c795144476beafe367e33d0148a8286b.jpg?v=1791162506","url":"https:\/\/voomisupply.com\/products\/collis-tool-74424-split-sleeve-tapping-driver-mt4","provider":"Voomi Supply","version":"1.0","type":"link"}
