It accepts a drill tang and drives a 0.277 inch diameter drill bit at a 1 inch drill depth. The tang thickness compatibility range runs from 0.158 to 0.162 inches, and the driver features a 3\/16 inch projection. Machinists and toolroom technicians use this type of driver to positively locate and drive taper-shank tooling in MT1 spindle bores without slippage.\u003c\/p\u003e\n\u003cp\u003eThis driver is suited for light-duty machining operations in shops requiring Letter J size drill access through a Morse taper No. 1 spindle. Typical applications include through-hole drilling, production work on benchtop drill presses, and lathe tailstock operations where a tang-drive interface provides secure tool engagement. It is appropriate for both manual machine shops and vocational training environments where MT1 tooling is standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMT1 outside Morse taper shank for positive engagement in No. 1 taper spindles\u003c\/li\u003e\n  \u003cli\u003eDrives Letter J drill size at 0.277 inch diameter\u003c\/li\u003e\n  \u003cli\u003e1 inch drill depth capacity\u003c\/li\u003e\n  \u003cli\u003eDrill tang compatible with 0.158 to 0.162 inch tang thickness range\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch projection for proper tool positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement driver for MT1 spindle machines requiring Letter J drill size capability with tang-drive engagement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing any Morse taper tooling. Clean the spindle bore and taper shank of all chips, oil, and debris before seating the driver to ensure full taper contact. Use a drift key through the spindle slot to safely eject the driver  -  never strike the drill or driver directly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Size (Decimal Inch)\u003c\/strong\u003e: 0.277 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Type\u003c\/strong\u003e: MT1 Outside Morse Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Size (Letter)\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Tang Compatible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Tang Thickness Range\u003c\/strong\u003e: 0.158 to 0.162 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3\/16 inches\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: 71203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COLLIS TOOL","offers":[{"title":"Default Title","offer_id":67913242444082,"sku":"71203","price":49.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1505dcf9227e76089f91a07dacaee07d_76340540-b9ee-4899-9a49-cca77812873e.jpg?v=1791243834","url":"https:\/\/voomisupply.com\/products\/collis-tool-71203-letter-j-mt1-morse-taper-drill-driver","provider":"Voomi Supply","version":"1.0","type":"link"}
