Built to a No. 60 wire gauge diameter of 0.0400 inches, it features a spiral flute geometry with left-hand spiral direction and right-hand cutting action. This combination helps evacuate chips efficiently while reducing chatter during the cut. The bright polished finish minimizes friction and heat buildup. With a 4-flute configuration and a diameter tolerance of 0.0000 to +0.0003 inches, it delivers consistent, repeatable hole quality. Machinists and tool and die professionals use it when tight bore tolerances are required on small-diameter holes.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for production and job-shop environments where small-diameter hole finishing demands close tolerances. The straight shank allows direct mounting in standard drill chucks, collet chucks, and floating reamer holders on CNC machining centers, lathes, and drill presses. The 7.00 mm flute length makes it appropriate for shallow-to-moderate depth applications in materials where solid carbide provides a rigidity and wear-resistance advantage over high-speed steel alternatives.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 60 wire size diameter — 0.0400 inches for precise small-bore finishing\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with left-hand spiral and right-hand cut for effective chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright polished finish reduces friction and aids chip flow\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of 0.0000 to +0.0003 inches for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003eStraight shank compatible with standard chucks and collet systems\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 toolholders, drill chucks, and collet chucks on CNC and manual machine tools requiring No. 60 wire gauge bore finishing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist familiar with reaming operations and cutting tool handling. Secure the straight shank fully in the holder and verify runout before cutting. Always reduce spindle speed relative to drilling and use appropriate cutting fluid for the workpiece material. Inspect the cutting edges before each use — solid carbide is brittle and should not be used in setups with excessive vibration or interrupted cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: No. 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright (Polished)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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: 7.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 to +0.0003 inches\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: MR34-0401.281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730078171442,"sku":"MR34-0401.281","price":107.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd5b5b81494e72a9d907861455516991.jpg?v=1788711374","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0401-281-chucking-reamer-no-60-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
