It features an MT3 taper shank for secure mounting in compatible spindles and machine tool holders. The driver accommodates a 1-1\/4 inch tap with a tap entry depth of 2.19 inches and a projection of 2-15\/16 inches. The tap shank diameter measures 1.021 inches, with a tap shank square of 0.766 inches. This tool is installed by machinists and tool-and-die professionals working with milling machines, drill presses, and lathes where tapping operations require a positive-drive holder.\u003c\/p\u003e\n\u003cp\u003eThe COLLIS TOOL 70305 is suited for production and job-shop tapping operations where repeatable tap engagement and secure drive are required. It is commonly used in vertical milling machines and drill presses with MT3-compatible spindles. The MT3 taper shank provides positive seating without the need for a drawbar in most applications, making it well suited for manual and semi-automatic tapping cycles in both ferrous and non-ferrous material work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT3 taper shank for direct spindle mounting in compatible machine tools\u003c\/li\u003e\n  \u003cli\u003eAccommodates 1-1\/4 inch taps with 1.021 inch shank diameter\u003c\/li\u003e\n  \u003cli\u003e2.19 inch tap entry depth for deep-reach tapping applications\u003c\/li\u003e\n  \u003cli\u003e2-15\/16 inch projection for clearance in standard work setups\u003c\/li\u003e\n  \u003cli\u003eTap shank square of 0.766 inches provides positive rotational drive\u003c\/li\u003e\n  \u003cli\u003eSingle-piece construction for consistent tap alignment and reduced runout\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style tapping driver for use in machine tool spindles with an MT3 Morse taper bore, compatible with 1-1\/4 inch taps having a 1.021 inch shank diameter and 0.766 inch square drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and machine tool operators. Before mounting, power down and lock out the machine spindle per applicable OSHA lockout\/tagout procedures. Clean the taper shank and spindle bore thoroughly before seating to ensure full contact and accurate alignment. Do not use excessive force to seat the taper; a firm hand press or soft mallet tap against a clean bore is the standard practice for MT-shank tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 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: 2-15\/16 inches\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\u003eWeight\u003c\/strong\u003e: 2.22 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 70305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLLIS TOOL","offers":[{"title":"Default Title","offer_id":67918398652722,"sku":"70305","price":172.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/58568846608ae90596d8f9abbfa9eec4.jpg?v=1791269586","url":"https:\/\/voomisupply.com\/products\/collis-tool-70305-standard-tapping-driver-mt3-taper-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
