With a 0.26 mm reamer diameter, this tool delivers a diameter tolerance of 0.0000 to +0.0003 mm, making it suitable for work that demands consistent, repeatable sizing. The spiral flute geometry with left-hand spiral direction promotes smooth chip evacuation while the right-hand cutting direction drives the tool forward. At 50 mm overall length with a 1.5 mm flute length, this is a micro-reamer built for fine-bore finishing in metalworking, mold and die, and precision machining environments. It ships uncoated with a bright finish and requires no special adapter beyond a standard straight-shank chuck.\u003c\/p\u003e\n\u003cp\u003eThis reamer is intended for use in CNC machining centers, drill presses, and precision lathes where bore finishing to close tolerances is required. The 0.26 mm diameter places it firmly in the micro-tooling range, making it a common choice for small-bore finishing in watch components, medical device components, electronics housings, and precision instrumentation. A licensed machinist or toolroom technician is the typical end user. The straight shank fits standard collet chucks and precision drill chucks sized for the shank diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in micro-bore applications\u003c\/li\u003e\n  \u003cli\u003e0.26 mm reamer diameter with tolerance of 0.0000 to +0.0003 mm for tight-tolerance finishing\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry with left-hand spiral and right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight shank for compatibility with standard collet and drill chuck setups\u003c\/li\u003e\n  \u003cli\u003e50 mm overall length with 1.5 mm flute length for controlled micro-bore engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision chucking reamer for use in straight-shank toolholders, collet chucks, and precision drill chucks sized to accept the shank diameter of this micro-reamer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with micro-tooling handling. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool from the chuck. Due to the micro diameter, handle with care to avoid deflection or chipping of the carbide flutes. Verify runout with a dial indicator before committing to a finishing pass, as even minor misalignment at this diameter will affect bore tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.26 mm (0.0102 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: 1.5 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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: MR34-0102.059\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744826097970,"sku":"MR34-0102.059","price":124.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cffeab4d1447e0dae1befc617f34eac9.jpg?v=1788861067","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0102-059-chucking-reamer-0-26mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
