Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing and smooth bore surfaces in production and job-shop environments. The reamer measures 1.750 inches in diameter with a 14-1\/2 inch overall length and a 4 inch straight flute section. A 4MT Morse taper shank provides secure, positive drive in drill press, lathe, or boring machine spindles. With 12 right-hand cutting flutes, this tool removes material uniformly and produces consistent finished hole dimensions. Machinists and tool-and-die professionals are the primary users of this style of reamer.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for reaming through-holes and blind holes in steel, cast iron, aluminum, and similar machinable materials. It is intended for use in machine spindles rather than hand operation. The 4MT taper shank is compatible with drill press quills, lathe tailstocks, and boring mill spindles that accept a No. 4 Morse taper socket. The 4 inch flute length accommodates moderate stock removal to bring drilled or bored holes to final tolerance. Typical applications include production machining, repair and maintenance shops, and toolroom work where bore accuracy and surface finish are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.750 inch (1-3\/4 inch) diameter for precision final-size finishing\u003c\/li\u003e\n  \u003cli\u003eHSS construction provides toughness and wear resistance across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003e12 straight flutes with right-hand cutting direction for smooth, chatter-resistant stock removal\u003c\/li\u003e\n  \u003cli\u003e4MT Morse taper shank seats securely in compatible machine spindles without additional toolholders\u003c\/li\u003e\n  \u003cli\u003e4 inch flute length handles typical through-hole and moderate-depth bore finishing\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish maintains dimensional accuracy and simplifies resharpening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in machine spindles, lathe tailstocks, drill presses, and boring mills equipped with a No. 4 Morse taper (4MT) socket.

Before mounting, ensure the spindle taper socket and reamer shank taper are clean and free of chips or burrs, as contamination will affect runout and hole accuracy. Power down the machine completely before inserting or removing the taper shank. Use the appropriate drift and drift slot to remove the reamer from the spindle — never strike the reamer body directly. Confirm proper cutting fluid application for the workpiece material to promote surface finish and tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1-3\/4 inches (1.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 14-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4 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\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\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\u003eWeight\u003c\/strong\u003e: 7 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: ST0140148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706658718002,"sku":"ST0140148","price":223.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4572c6168da8b55c6257646781b82ee.jpg?v=1788435928","url":"https:\/\/voomisupply.com\/products\/value-collection-st0140148-chucking-reamer-1-3-4-in-hss-4mt","provider":"Voomi Supply","version":"1.0","type":"link"}
