Built with a straight flute geometry and a straight-cylindrical shank, this reamer seats cleanly in standard drill chucks and boring heads. It runs with right-hand cutting direction, making it compatible with conventional machine spindle rotation. With a 9-inch overall length and a 2.25-inch flute length, it provides adequate reach for typical through-hole and blind-hole finishing operations. Machinists and toolroom technicians use this reamer to achieve tight dimensional tolerances and improved surface finish in ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for use in drill presses, lathes, milling machines, and CNC machining centers where a precise finish bore is required after initial drilling. It is appropriate for production and maintenance machining environments. The bright, uncoated HSS construction makes it a practical choice for general-purpose reaming where specialized coatings are not required. It fits operations where hole diameter falls within the 0.5000- to 0.6999-inch range, and it is sold individually with a minimum order quantity of one piece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReamer diameter of 0.6840 inches for precise hole finishing\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction provides good wear resistance in general machining applications\u003c\/li\u003e\n\u003cli\u003eStraight flute design suits most standard reaming operations in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank seats securely in drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard machine spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no additional coating to affect dimensional tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose chucking reamer for use in drill presses, lathes, milling machines, and machining centers requiring finish reaming of holes in the 0.5000- to 0.6999-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or toolroom technician. Always power down and lock out the machine spindle before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in a properly sized drill chuck or collet to minimize runout. Use appropriate cutting fluid for the workpiece material and inspect the cutting edges for wear or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.6840 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.25 inches\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\u003eFlute Type\u003c\/strong\u003e: Straight\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: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\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: SM0406840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691141038386,"sku":"SM0406840","price":52.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdcf9d4b85491a5ef1c9e85e116aa4ae.jpg?v=1788280769","url":"https:\/\/voomisupply.com\/products\/value-collection-sm0406840-chucking-reamer-0-6840-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
