With a reamer diameter of 0.0449 inches (1.14 mm) and a four-flute spiral configuration, it delivers consistent bore sizing and a bright polished finish in tight-tolerance work. The straight shank mounts directly in standard chucks or collets on CNC machining centers, drill presses, and lathes. Cutting direction is right hand with left-hand spiral flutes, a geometry that helps control chip evacuation in through-hole operations. Overall length is 1.9685 inches (50.00 mm) with a flute length of 0.7087 inches (10.00 mm). Machinists and toolroom technicians working in production or repair environments are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for finishing small-diameter bores in ferrous and non-ferrous metals, plastics, and composite materials where hole size tolerance is critical. The 0.0449-inch diameter falls within the 0 to 0.0499-inch decimal inch range, making it appropriate for micro-bore applications in instrument components, medical device parts, precision fixtures, and small mechanical assemblies. The bright (polished) coating reduces friction and helps maintain surface finish quality in both through-hole and blind-hole configurations. It is intended for use on machine tools, not for hand reaming.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision boring operations\u003c\/li\u003e\n  \u003cli\u003eFour-flute spiral geometry with left-hand spiral and right-hand cutting direction for controlled chip flow\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of 0.0000 to +0.0003 mm for tight-tolerance hole finishing\u003c\/li\u003e\n  \u003cli\u003eBright (polished) coating minimizes friction and supports clean surface finish\u003c\/li\u003e\n  \u003cli\u003eStraight shank compatible with standard chucks and collets on CNC and manual machine tools\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1.9685 inches suits confined workpiece access and short-reach setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a machine chucking reamer for use in standard straight-shank tool holders, collet chucks, and drill chucks on CNC machining centers, lathes, and drill presses capable of accepting the 0.0449-inch diameter shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and operated by machinists and toolroom technicians on powered machine tools only — it is not intended for hand reaming. Secure the straight shank firmly in a collet or drill chuck before operation and verify runout with an indicator before cutting to protect the carbide from chipping. Power down and de-energize the machine spindle completely before changing or inspecting the reamer. Carbide tooling is brittle — avoid dropping or contacting hard surfaces during handling and storage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.0449 inches (1.14 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0 to 0.0499 inches (1.00 to 2.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.9685 inches (50.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.7087 inches (10.00 mm)\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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: Left Hand\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\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\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 to +0.0003 mm\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: 0.1 pounds\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MR34-0449.406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732358201650,"sku":"MR34-0449.406","price":84.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/520f5bf697a060d000f30d00528e7c97_572b76c8-6057-4317-bcf8-9d19d41178c1.jpg?v=1788742022","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0449-406-chucking-reamer-0-0449-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
