Straight flutes cut in a right-hand direction, making this tool suitable for machine spindle work where a smooth, accurate taper seat is required. The small end diameter measures 1.0167 inches and the large end diameter measures 1.2893 inches, with an overall length of 10.875 inches and a flute length of 5.25 inches. Constructed from high-speed steel with a bright, uncoated finish, this reamer delivers consistent cutting performance in standard machine shop and maintenance applications.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for finishing or enlarging 4MT Morse taper sockets in drill press tables, lathe tailstocks, milling machine spindles, and similar machine tool components. It is appropriate for job shop machinists, tool-and-die work, and maintenance technicians refurbishing worn or damaged taper bores. The 1.125-inch tapered shank seats directly into a compatible taper holder or adapter for rigid setup on manual or CNC equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4MT Morse taper profile for finishing standard No. 4 Morse taper bores\u003c\/li\u003e\n\u003cli\u003eSmall end diameter: 1.0167 inches; large end diameter: 1.2893 inches\u003c\/li\u003e\n\u003cli\u003eStraight flute geometry with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for wear resistance across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating to affect dimensional tolerances\u003c\/li\u003e\n\u003cli\u003eOverall length of 10.875 inches with a 5.25-inch flute length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or stock reamer for any application requiring a No. 4 Morse taper bore finish to standard 4MT dimensional specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists and tool-and-die technicians using a lathe, drill press, or milling machine with an appropriate taper adapter. Always power down and lock out the machine before mounting or removing the reamer. Use cutting fluid appropriate to the workpiece material to extend tool life and improve bore finish. Do not force the reamer through an undersized bore in a single pass; approach final dimension in light, progressive cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size Designation\u003c\/strong\u003e: 4MT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1.0167 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 1.2893 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 10.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ST09MTM4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722136322354,"sku":"ST09MTM4","price":121.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74b396e115c39f6b8da65b723fd99473.jpg?v=1788586290","url":"https:\/\/voomisupply.com\/products\/value-collection-st09mtm4-4mt-morse-taper-reamer-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
