With a 0.438 inch diameter and a diameter tolerance of +0.0003 to -0.0000 inches, this reamer holds size accurately for precision bore finishing in metal fabrication and machining applications. The 4-flute straight configuration and bright uncoated finish make it well suited for use in drill presses, lathes, and CNC machining centers. At 7 inches overall length with a 1.75 inch flute length, it offers adequate reach for most standard workpiece thicknesses. Machinists and tool-and-die technicians are the primary users of this type of reamer.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is used in machine-based holemaking operations where a drilled or bored hole must be brought to a final diameter with consistent roundness and surface finish. The straight cylindrical shank allows direct mounting in standard drill chucks or collet holders. It is appropriate for right-hand cutting operations in ferrous and non-ferrous materials. Typical applications include production runs requiring repeatable hole sizing, fixture fabrication, and component finishing work in job shops and manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide-tipped cutting edges for extended tool life in abrasive or harder materials\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0003 to -0.0000 inches for precise final hole sizing\u003c\/li\u003e\n  \u003cli\u003e4-flute straight configuration promotes smooth chip evacuation and consistent finish\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank for direct mounting in standard chucks or collet holders\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish  -  no coating buildup to affect dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard machine spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer for use in drill presses, lathes, and machining centers that accept straight-shank tooling in the applicable diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this reamer should be performed by a qualified machinist or toolroom technician. Before mounting, ensure the machine spindle is fully stopped and the chuck or collet is clean and free of debris to prevent runout. Secure the straight shank firmly in the chuck or collet holder before beginning the reaming pass, and use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Never use a hand reamer in a power machine, and do not attempt to remove excessive stock in a single reaming pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0003 to -0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.75 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 Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide-Tipped\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 0.01 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: 24004380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":68386768191794,"sku":"24004380","price":221.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbed389c3be222828dc8612c328fa519.jpg?v=1793903519","url":"https:\/\/voomisupply.com\/products\/value-collection-24004380-chucking-reamer-0-438-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
