With a 1-9\/16 inch (1.5625 inch decimal) diameter and a 4MT Morse taper shank, this reamer mounts directly into compatible taper-socket spindles and tailstocks for stable, concentric cutting. The 3-1\/2 inch straight-flute cutting section spans 12 flutes arranged for right-hand cutting, delivering smooth material removal and tight dimensional tolerances. The bright, uncoated HSS construction is well suited to a broad range of ferrous and non-ferrous workpiece materials. Machinists and tool-and-die technicians are the primary installers of this reamer.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is intended for use in lathes, drill presses, milling machines, and machining centers equipped with a No. 4 Morse taper socket. It is appropriate for finish-reaming through-holes and blind holes in production and job-shop environments where precise bore diameter and surface finish are required. The 12-1\/2 inch overall length provides adequate reach for deeper bores while maintaining rigidity through the Morse taper shank interface. It is a standard choice for ferrous machining tasks where HSS tooling is preferred over carbide.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-9\/16 inch (1.5625 inch) reamer diameter for precise bore sizing\u003c\/li\u003e\n  \u003cli\u003e12 straight flutes with right-hand cutting direction for smooth, controlled material removal\u003c\/li\u003e\n  \u003cli\u003eNo. 4 Morse taper (4MT) shank for direct mounting in compatible spindles and tailstocks\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction — bright, uncoated finish suitable for general-purpose machining\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inch flute length provides adequate cutting engagement for standard bore depths\u003c\/li\u003e\n  \u003cli\u003e12-1\/2 inch overall length for extended reach in deeper hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in machine tool spindles and lathe tailstocks equipped with a No. 4 Morse taper (4MT) socket.

Before mounting, ensure the machine spindle or tailstock is fully powered down and at a complete stop. Clean the Morse taper shank and receiving socket thoroughly before seating to ensure full contact and concentricity. Use a drift key and proper knockout bar to remove the reamer — never strike the tool body directly to dislodge it from the taper.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1-9\/16 inches (1.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 12-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 12\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\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: 5 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: ST0140136\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698312937778,"sku":"ST0140136","price":209.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf5e7e895ad2de27a7b00cea009c566d.jpg?v=1788361006","url":"https:\/\/voomisupply.com\/products\/value-collection-st0140136-chucking-reamer-hss-4mt","provider":"Voomi Supply","version":"1.0","type":"link"}
