With a 0.0138-inch diameter, a 1.9685-inch overall length, and a 2.00 mm flute length, this tool is built for micro-bore reaming where dimensional accuracy is critical. The four-flute spiral design with a left-hand spiral and right-hand cutting direction promotes smooth chip evacuation and a consistent surface finish. A bright polished coating reduces friction and helps maintain cutting geometry. Machinists and tool-and-die professionals install this reamer in CNC machining centers, drill presses, or manual lathes for final sizing of precision bores.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for production and repair environments where bore tolerances are extremely tight. The straight shank provides direct, concentric chuck engagement in standard collets and drill chucks. Applications include precision instrument components, small-diameter hydraulic passages, and medical or aerospace part finishing where a reamer diameter tolerance of 0.0000 to +0.0003 mm is required. The solid carbide construction handles hard workpiece materials that would quickly wear high-speed steel tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eFour-flute spiral design with left-hand spiral for improved chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard machine spindle rotation\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces friction and aids chip clearance\u003c\/li\u003e\n  \u003cli\u003eReamer diameter tolerance of 0.0000 to +0.0003 mm for tight bore control\u003c\/li\u003e\n  \u003cli\u003eStraight shank for direct chuck or collet mounting without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide chucking reamer for use in CNC and manual machine tool setups requiring a 0.0138-inch straight-shank reamer with a standard straight-shank interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this reamer should be performed by qualified machinists or toolroom professionals. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the straight shank in a collet or drill chuck to the appropriate torque for the chuck type to maintain concentricity. Use recommended cutting fluid for the workpiece material to preserve coating integrity and tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.0138 inches (0.35 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: 2.00 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\u003eReamer Diameter Tolerance\u003c\/strong\u003e: 0.0000 to +0.0003 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: MR34-0138.079\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728223273266,"sku":"MR34-0138.079","price":163.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/520f5bf697a060d000f30d00528e7c97_9e2cd12f-cf3e-4ff6-9637-1c9a2d4bf3e2.jpg?v=1788689829","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0138-079-chucking-reamer-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
