Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer features 10 spiral flutes with a right-hand cutting direction for smooth, accurate material removal. The 4MT (No. 4 Morse Taper) shank seats directly into compatible machine spindles, providing rigid, concentric drive without a separate chuck. At 11.5 inches overall length with a 3-inch flute length, it is sized for mid-depth boring operations on drill presses, lathes, and milling machines. Machinists and tool-and-die professionals are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for production and maintenance machining environments where hole tolerances require a finishing pass after drilling. It is appropriate for use in ferrous and non-ferrous metals including steel, cast iron, and aluminum. The Morse taper shank allows direct mounting in machine spindles equipped with a No. 4 Morse Taper socket, which is common on mid-size and large drill presses and lathes. It is not configured as a dowel pin reamer and is not an over or under-size variant, making it a standard finishing reamer for nominal 1-1\/4-inch bore specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.2500-inch (1-1\/4 inch) finished bore diameter for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e10 spiral flutes with right-hand cutting direction for smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003eNo. 4 Morse Taper (4MT) shank for direct spindle mounting without an adapter chuck\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across a wide range of metals\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suited for general-purpose machining\u003c\/li\u003e\n  \u003cli\u003e3-inch flute length accommodates mid-depth finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard finishing chucking reamer for use in machine spindles accepting a No. 4 Morse Taper shank, including mid-size and large drill presses, engine lathes, and milling machines configured for 4MT tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists and tool-and-die technicians. Power down and lock out the machine before seating or removing the Morse taper shank. Ensure the spindle socket and taper shank are clean and free of chips or burrs before insertion to maintain concentricity. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve the specified finish tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 11-1\/2 inches (11.0000 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Morse Taper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Taper Designation\u003c\/strong\u003e: 4MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: HSS (High-Speed Steel)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ST0240116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691211489586,"sku":"ST0240116","price":147.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbb5ad3632f4214640999eda89112973.jpg?v=1788281592","url":"https:\/\/voomisupply.com\/products\/value-collection-st0240116-chucking-reamer-1-1-4-in-hss-4mt","provider":"Voomi Supply","version":"1.0","type":"link"}
