With a 0.77 mm reamer diameter and a diameter tolerance of 0.0000 to +0.0003 mm, this tool holds the dimensional accuracy required for close-fit bores in metal components. The spiral flute geometry with left-hand spiral direction promotes smooth chip evacuation, while the right-hand cutting direction drives consistent material removal. The straight shank is compatible with standard collet and drill chuck setups. At 50 mm overall length with a 7 mm flute length, this reamer is built for short, precise reaming passes in machining environments.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for machine shop and production machining operations where sub-millimeter bore finishing is required. The solid carbide construction handles hardened and abrasive workpiece materials that would accelerate wear on high-speed steel tooling. With four flutes and a bright uncoated finish, this tool is typically run in CNC machining centers, drill presses, or turret lathes where controlled feed rates and rigid setup conditions can be maintained. It is sized for micro-bore work in the 0.00 to 1.00 mm reamer diameter range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for wear resistance in hardened and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e0.77 mm reamer diameter with a tight tolerance of 0.0000 to +0.0003 mm\u003c\/li\u003e\n  \u003cli\u003eLeft-hand spiral flute for efficient chip evacuation during right-hand cutting\u003c\/li\u003e\n  \u003cli\u003eFour flutes for improved surface finish and bore roundness\u003c\/li\u003e\n  \u003cli\u003eStraight shank for use with standard collet chucks and drill chucks\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluids across a range of workpiece materials\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 machine tool setups requiring straight shank, spiral-flute reamers in the sub-millimeter diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eChucking reamers of this diameter should be installed by a qualified machinist in a rigid, concentric tool holder to minimize runout. Ensure the machine spindle and workpiece are properly secured before engaging the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve the specified bore tolerance. Avoid hand-feeding at inconsistent rates, as this can cause chatter and compromise bore finish at this diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.77 mm (0.0303 inches)\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\u003eOverall Length\u003c\/strong\u003e: 50 mm (1.9685 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: MR34-0303.281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728559604018,"sku":"MR34-0303.281","price":99.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df5cb50c9192071c015d36309bc9dbbe.jpg?v=1788693334","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0303-281-chucking-reamer-0-77mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
