With a reamer diameter of 1.01 mm and a tight tolerance of 0.0000 to +0.0003 mm, this tool delivers accurate, repeatable hole sizing in small-bore work. The spiral flute geometry with left-hand spiral direction helps evacuate chips efficiently while the right-hand cutting action engages the workpiece cleanly. Overall length is 50 mm with a 7 mm flute length and a straight shank for standard chuck mounting. Machinists and toolroom technicians working with CNC machining centers, drill presses, or manual lathes will find this reamer suited for tight-tolerance finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is intended for finishing operations on small-diameter holes in ferrous and non-ferrous metals, plastics, and other machinable materials. The solid carbide construction makes it appropriate for use in harder workpiece materials and high-speed applications where high-speed steel tooling would wear prematurely. It is well suited for production machining environments, toolroom work, and precision repair applications where hole geometry and surface finish are critical. The straight shank is compatible with standard collet chucks and drill chucks used on CNC and manual machine tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.01 mm reamer diameter with a tolerance of 0.0000 to +0.0003 mm for precision hole sizing\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity, wear resistance, and performance in harder materials\u003c\/li\u003e\n  \u003cli\u003eLeft-hand spiral flute geometry promotes efficient chip evacuation during right-hand cutting\u003c\/li\u003e\n  \u003cli\u003e4-flute design provides stable cutting action and improved surface finish in the bore\u003c\/li\u003e\n  \u003cli\u003eStraight shank for direct mounting in collet chucks or standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for a wide range of workpiece materials without coating interference\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 standard straight-shank collet chucks and drill chucks on CNC machining centers, manual mills, drill presses, and lathes capable of accepting small-diameter tooling in the 1 mm 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 familiar with small-diameter precision tooling. Ensure the machine spindle and chuck are fully stopped and the machine is powered down before loading or unloading the reamer. Secure the straight shank firmly in a correctly sized collet or drill chuck to minimize runout, as even slight runout at this diameter can affect tolerance and tool life. Use appropriate cutting fluid for the workpiece material and avoid forcing the tool — reamers are finishing tools and should remove only a small amount of material per pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1.01 mm (0.0398 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\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\/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: MR34-0398.281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753214279986,"sku":"MR34-0398.281","price":107.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42ff38b6f98e54e82888d486084fa0bb.jpg?v=1788933972","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0398-281-chucking-reamer-1-01mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
