It features a straight flute geometry and a straight shank for use in standard drill chucks and collet holders. With an overall length of 6 inches and a flute length of 1.5 inches, this four-flute reamer is built for right-hand cutting in production and job-shop holemaking operations. The bright, polished finish reduces friction and aids chip evacuation. Machinists and tool and die professionals rely on this style of reamer to bring drilled or bored holes to final size and finish.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for finishing holes in ferrous and non-ferrous materials where close dimensional control is required. Letter N sizing places the finished bore in the 0.3000 to 0.3499 inch diameter range, making it a common choice for precision fit applications in manufacturing, maintenance, and repair environments. It is intended for use in a machine spindle  -  mill, drill press, or lathe  -  not for hand reaming. The straight flute design is appropriate for through-holes and short blind holes where chip control is manageable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter N diameter  -  0.3020 inches decimal equivalent\u003c\/li\u003e\n  \u003cli\u003eTight tolerance of +0.0003 to -0.0000 inches for precise final sizing\u003c\/li\u003e\n  \u003cli\u003eFour straight flutes with bright polished finish for smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight shank for compatibility with standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003e6 inch overall length with 1.5 inch flute length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a machine-use chucking reamer for straight-shank toolholders, collet chucks, and drill chucks in mills, drill presses, and lathes where Letter N diameter holes are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis reamer is intended for machine spindle use only  -  do not use as a hand reamer. Secure the straight shank firmly in a collet or drill chuck before operation. Ensure the workpiece is rigidly fixtured and the spindle is properly aligned to the existing pilot hole to avoid deflection and oversize conditions. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Letter)\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.3020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.3000 to 0.3499 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Tolerance\u003c\/strong\u003e: +0.0003 to -0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright (Polished)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDowel Pin Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\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: 24003020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":68385159348530,"sku":"24003020","price":231.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/961102ce9fba2db588e330f991528132.jpg?v=1793902459","url":"https:\/\/voomisupply.com\/products\/value-collection-24003020-chucking-reamer-letter-n","provider":"Voomi Supply","version":"1.0","type":"link"}
