With a 0.33 mm reamer diameter and a diameter tolerance of 0.0000 to +0.0003 mm, this tool is built for applications where dimensional accuracy is non-negotiable. The spiral flute geometry, combined with a left-hand spiral direction and right-hand cutting direction, helps evacuate chips efficiently and reduces chatter during the cut. The bright polished finish minimizes built-up edge and supports smooth surface finish in the bore. Machinists and tool-room professionals install this reamer in CNC machining centers and precision drill presses using a straight shank collet or drill chuck setup.\u003c\/p\u003e\n\u003cp\u003eThis reamer is suited for precision bore finishing in production and tool-room environments where micro-diameter holes require consistent sizing. With a 2 mm flute length and 50 mm overall length, it is intended for shallow, close-tolerance bores in small or intricate workpieces. Typical applications include watch components, medical device parts, instrument housings, and other work requiring sub-millimeter bore accuracy. The solid carbide construction performs well in hardened steels, cast iron, aluminum, and other materials that demand rigidity and edge retention at small diameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and edge retention at sub-millimeter diameters\u003c\/li\u003e\n  \u003cli\u003e0.33 mm reamer diameter with tolerance of 0.0000 to +0.0003 mm for tight bore sizing\u003c\/li\u003e\n  \u003cli\u003eLeft-hand spiral flute promotes efficient chip evacuation and reduced chatter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces built-up edge and supports smooth bore surface finish\u003c\/li\u003e\n  \u003cli\u003eStraight shank for use in standard collets or drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision reamer for use in CNC machining centers, manual drill presses, and precision lathes equipped with straight-shank collet or drill chuck tooling capable of holding a 0.33 mm diameter shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis reamer should be installed and operated by a qualified machinist familiar with micro-diameter tooling. Ensure the spindle and workpiece are properly secured and that runout is minimized before engaging the cut, as micro-diameter carbide tools are brittle and will fracture under lateral load or excessive runout. Use a cutting fluid appropriate for the workpiece material to protect the cutting edge and maintain bore finish. Do not force-feed or exceed recommended feed rates for the diameter, as carbide reamers at this size have very limited deflection tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.33 mm (0.0130 inches)\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: 2 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 Dimensions\u003c\/strong\u003e: 0.25 x 0.25 x 3 inches\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: MR34-0130.079\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729771430194,"sku":"MR34-0130.079","price":166.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9a150d6fbc8f1897f0351b51baf8b18.jpg?v=1788709209","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0130-079-chucking-reamer-0-33mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
