With a 2.29 mm reamer diameter and a tight diameter tolerance of 0.0000 to +0.0003 mm, this tool delivers accurate, repeatable bore sizing in close-tolerance work. The spiral flute geometry with left-hand spiral direction helps evacuate chips efficiently while the right-hand cutting direction drives the tool forward. At 50 mm overall length with an 11 mm flute length, this compact reamer suits small-bore finishing operations where precision is critical. Machinists and tool-and-die professionals select this tool for production and repair work requiring consistent hole quality.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is suited for use in CNC machining centers, drill presses, and lathes where a straight shank can be clamped directly in a chuck or collet. The 2.29 mm diameter falls within the 2.00 to 3.00 mm range, making it appropriate for small-diameter precision bores in ferrous and non-ferrous materials. The bright, uncoated finish maintains dimensional accuracy without coating buildup affecting finished hole size. Four flutes provide a balance of chip clearance and surface finish quality in reamed holes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in precision reaming\u003c\/li\u003e\n  \u003cli\u003e2.29 mm reamer diameter with tolerance of 0.0000 to +0.0003 mm for close-tolerance bore finishing\u003c\/li\u003e\n  \u003cli\u003eLeft-hand spiral flutes with right-hand cut for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e4-flute design balancing surface finish quality and chip clearance\u003c\/li\u003e\n  \u003cli\u003eStraight shank for direct clamping in chucks or collets\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish to preserve dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style chucking reamer compatible with CNC machining centers, drill presses, and lathes accepting a straight-shank tool in the 2.00 to 3.00 mm diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this reamer should be performed by qualified machinists following established shop safety procedures. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool from the chuck or collet. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish. Avoid forcing the reamer into an undersized pilot hole — bore or drill to the correct pre-ream diameter before finishing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 2.29 mm (0.0902 inches)\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\u003eOverall Length\u003c\/strong\u003e: 50 mm (1.9685 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11 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\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: MR34-0901.438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728225698098,"sku":"MR34-0901.438","price":274.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e6667413e4869158425be1a23017865.jpg?v=1788689878","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0901-438-chucking-reamer-2-29mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
