It provides a 1\/4 inch projection and accepts drill tangs ranging from 0.199 to 0.203 inches in thickness. The 72309 is built for use in drill presses, milling machines, lathes, and similar machine tools where a Morse taper spindle interface is required. Machinists and tool room technicians rely on this type of driver to securely seat drills and transmit torque without slippage during metal cutting operations.\u003c\/p\u003e\n\u003cp\u003eThis drill driver is suited for production machining and tool room environments where letter-size drills are used in repetitive drilling operations. The MT2 taper shank provides positive self-locking engagement with compatible spindle sockets. The Letter U designation corresponds to a decimal drill size of 0.368 inches, making this driver applicable to precision hole-making in metalworking, fabrication, and maintenance machining scenarios.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter U drill size with 0.368 inch decimal equivalent\u003c\/li\u003e\n  \u003cli\u003eMT2 outside Morse taper shank for positive spindle engagement\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch projection for proper drill seating depth\u003c\/li\u003e\n  \u003cli\u003eCompatible with drill tangs from 0.199 to 0.203 inches thick\u003c\/li\u003e\n  \u003cli\u003e1-1\/8 inch drill depth capacity\u003c\/li\u003e\n  \u003cli\u003eDrill tang compatible design for secure torque transmission\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style driver for use with MT2 Morse taper spindles accepting Letter U drill size tooling with a drill tang thickness of 0.199 to 0.203 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians familiar with Morse taper tooling. Before seating the driver, ensure the spindle socket and taper shank are clean and free of chips, oil, or burrs, as contamination will prevent proper self-locking engagement. Insert the taper with a firm upward push and verify it is fully seated before operating the machine. To remove, use a drift punch through the spindle drift slot  -  never attempt to pry the taper free from the side.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Size (Letter)\u003c\/strong\u003e: U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Size (Decimal Inch)\u003c\/strong\u003e: 0.368 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Type\u003c\/strong\u003e: MT2 Outside Morse Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Tang Thickness\u003c\/strong\u003e: 0.199 to 0.203 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth\u003c\/strong\u003e: 1-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Tang Compatible\u003c\/strong\u003e: Yes\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: 72309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLLIS TOOL","offers":[{"title":"Default Title","offer_id":67910994723122,"sku":"72309","price":52.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1505dcf9227e76089f91a07dacaee07d_7670c7f1-05a7-4021-afb7-2f2d3a5057a3.jpg?v=1791202791","url":"https:\/\/voomisupply.com\/products\/collis-tool-72309-letter-u-mt2-drill-driver-0-368-in","provider":"Voomi Supply","version":"1.0","type":"link"}
