With a 1.57 mm reamer diameter, a 50 mm overall length, and a 10 mm spiral flute length, this tool delivers tight tolerances in small-bore work. The bright, uncoated solid carbide construction provides rigidity and wear resistance suited to close-tolerance reaming passes. The four-flute spiral configuration with left-hand spiral direction and right-hand cutting direction reduces chatter and promotes smooth chip evacuation. Machinists and tool-and-die professionals working on precision components, jigs, or fixtures will find this reamer fits standard CNC and manual chucking setups.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is built for finishing operations where hole diameter control is critical. It is suited to light material removal passes in ferrous and non-ferrous metals, plastics, and similar machinable materials. The straight shank makes it compatible with standard drill chucks and collet holders commonly found in machining centers, lathes, and drill presses. The reamer diameter tolerance of 0.0000 to +0.0003 mm makes it appropriate for tight-fit dowel and bearing bore applications in precision manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision reaming\u003c\/li\u003e\n\u003cli\u003e1.57 mm reamer diameter with a tolerance of 0.0000 to +0.0003 mm\u003c\/li\u003e\n\u003cli\u003eFour flutes with left-hand spiral direction for reduced chatter and smooth chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard forward-feed operation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect bore geometry\u003c\/li\u003e\n\u003cli\u003eStraight shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide chucking reamer for use in standard straight-shank chuck and collet tooling systems across CNC machining centers, manual lathes, and drill presses.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with precision reaming operations. Secure the straight shank firmly in a drill chuck or collet holder before use and verify runout before taking a finishing pass. Always deburr and pre-drill the bore to near-final size before reaming; this tool is designed for light finishing cuts only. Follow applicable shop safety procedures and machine guarding requirements when operating rotating cutting tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1.57 mm (0.0618 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: 10 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\u003eReamer Diameter 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: MR34-0618.406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749375607090,"sku":"MR34-0618.406","price":109.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5a5c367161283c1614f9085f459c3a7.jpg?v=1788905242","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0618-406-chucking-reamer-1-57mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
