With a 1.35 mm reamer diameter, the tool holds a tolerance of 0.0000 to +0.0003 mm, making it well-suited for applications that demand consistent, repeatable bore sizing. The spiral flute geometry, combined with a right-hand cutting direction and left-hand spiral, promotes smooth chip evacuation and reduces chatter during the cut. At 50 mm overall length with a 10 mm flute length, this compact reamer fits standard chuck setups. It is installed and used by machinists and toolroom technicians working on precision components.\u003c\/p\u003e\n\u003cp\u003eThis reamer is intended for use in CNC machining centers, drill presses, and manual mills where small-diameter hole finishing is required. The straight shank allows direct clamping in standard drill chucks or collet holders without additional adapters. The bright polished finish reduces friction and aids in chip flow, particularly useful when reaming non-ferrous metals, plastics, or other materials that demand a clean bore finish. Its compact size makes it a practical choice for micro-bore finishing operations in tight workpiece geometries.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance for small-diameter precision reaming\u003c\/li\u003e\n  \u003cli\u003e1.35 mm diameter with a tight tolerance of 0.0000 to +0.0003 mm for consistent bore sizing\u003c\/li\u003e\n  \u003cli\u003eSpiral flute with left-hand helix and right-hand cut promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces friction and extends tool life in compatible materials\u003c\/li\u003e\n  \u003cli\u003e4-flute design improves surface finish quality in the finished bore\u003c\/li\u003e\n  \u003cli\u003eStraight shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide chucking reamer suitable for standard straight-shank chuck and collet holder setups used in precision small-diameter hole finishing operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by machinists using a compatible drill chuck or collet holder sized for a straight shank. Ensure the workpiece is securely fixtured and the spindle is aligned to the bore axis before engaging the reamer to avoid deflection and tolerance loss. Always use appropriate cutting fluid for the workpiece material to protect the cutting edge and promote surface finish quality. Inspect the tool for chipping or wear before each use, as solid carbide tooling at this diameter is sensitive to lateral loading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1.35 mm (0.0531 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter 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: 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 (Polished)\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: MR34-0531.406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753877766450,"sku":"MR34-0531.406","price":109.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b9bca318b46c9b4566af17ac115ad4b.jpg?v=1788941753","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0531-406-chucking-reamer-1-35mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
