The driver accepts a 3\/4 inch pipe tap and provides 1-11\/16 inches of tap entry depth, giving machinists and maintenance technicians adequate reach for through-hole and blind-hole pipe thread applications. The split sleeve design allows the tap to be held securely while permitting controlled axial float during the tapping cycle. With a tap shank diameter of 0.906 inches and a tap shank square of 0.679 inches, the 74452 is built for use in machining centers, drill presses, and manual milling operations where consistent pipe thread quality is required.\u003c\/p\u003e\u003cp\u003eThis tapping driver is suited for metalworking shops, industrial maintenance facilities, and trade professionals who require precision pipe thread tapping in steel, iron, and similar ferrous materials. The MT4 taper shank mounts directly into compatible machine spindles without an intermediate adapter. The 3\/8 inch projection positions the tap close to the spindle face, reducing deflection and improving thread accuracy in production or repair settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMT4 taper shank for direct spindle mounting without an adapter\u003c\/li\u003e\n\u003cli\u003eSplit sleeve design secures 3\/4 inch pipe taps with controlled axial float\u003c\/li\u003e\n\u003cli\u003e1-11\/16 inch tap entry depth for through-hole and blind-hole applications\u003c\/li\u003e\n\u003cli\u003e0.906 inch tap shank diameter and 0.679 inch tap shank square for precise tap retention\u003c\/li\u003e\n\u003cli\u003e3\/8 inch projection minimizes overhang and reduces tap deflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/4 inch pipe taps featuring a 0.906 inch shank diameter and 0.679 inch shank square, mounted in machine spindles accepting an MT4 taper shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians with experience in machine tapping operations. Power down and lock out the machine spindle before inserting or removing the taper shank driver. Ensure the MT4 taper and spindle socket are clean and free of chips or burrs before seating the shank. Follow the machine manufacturer guidelines and applicable shop safety procedures when setting feed rate and speed for pipe thread tapping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Size\u003c\/strong\u003e: 3\/4 inch pipe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Entry Depth\u003c\/strong\u003e: 1-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: MT4 taper shank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Shank Diameter\u003c\/strong\u003e: 0.906 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTap Shank Square\u003c\/strong\u003e: 0.679 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: 1 pound\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: 74452\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLLIS TOOL","offers":[{"title":"Default Title","offer_id":67911712211250,"sku":"74452","price":93.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b94161496d6f9538ac536303f7ccda0.jpg?v=1791217478","url":"https:\/\/voomisupply.com\/products\/collis-tool-74452-mt4-taper-shank-pipe-tap-driver","provider":"Voomi Supply","version":"1.0","type":"link"}
