Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers clean, accurate sizing in ferrous and non-ferrous materials. The straight-cylindrical shank mounts directly into a drill press, lathe, or CNC machine chuck. Six straight flutes with a right-hand cutting direction provide consistent chip evacuation and a smooth bore finish. Machinists and tool-and-die professionals use this reamer as a finishing step to achieve tight dimensional tolerances that drilling alone cannot produce.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for machine-shop and production environments where repeatable hole sizing is required. The 0.3940 inch diameter falls within the 0.3500 to 0.3999 inch decimal-inch range, making it a practical choice for precision fit applications in metal fabrication, maintenance, and toolroom work. It is intended for use in a rigid machine setup rather than hand operation, ensuring concentricity and surface finish quality in the finished bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.3940 inch reamer diameter for precise final bore sizing\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSix straight flutes for smooth chip flow and consistent finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard machine rotation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for direct chuck mounting on drill presses, lathes, and CNC machines\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no added coating to affect dimensional tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a machine chucking reamer for use in drill presses, engine lathes, milling machines, and CNC machining centers equipped with a standard straight-bore chuck capable of accepting a straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or experienced toolroom technician should secure the reamer firmly in a rigid chuck before operation. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Do not use this reamer for freehand or hand-reaming applications — it is designed exclusively for machine use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.3940 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 0.3500 to 0.3999 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright, Uncoated\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.79 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: 144429603940000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702327083314,"sku":"144429603940000","price":74.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9eb93734b158d7d9412e0650255d438.jpg?v=1788410374","url":"https:\/\/voomisupply.com\/products\/value-collection-144429603940000-chucking-reamer-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
