With a reamer diameter of 1.22 mm and a diameter tolerance of 0.0000 to +0.0003 mm, this tool holds tight dimensional control in small-bore work. The 4-flute spiral configuration with left-hand spiral direction and right-hand cutting action reduces chatter and improves chip evacuation. Overall length is 50 mm with a 10 mm flute length. The bright, uncoated finish is suitable for a range of ferrous and non-ferrous workpiece materials. Machinists and tool-and-die professionals use this reamer in CNC or manual drilling operations requiring precise final bore sizing.\u003c\/p\u003e\n\u003cp\u003eThis chucking reamer is intended for small-diameter precision reaming where bore finish and dimensional accuracy are critical. The straight shank allows it to seat in standard collet chucks and drill chucks without modification. It is well suited to production or job-shop environments where consistent hole quality is required across multiple parts. The 1.22 mm diameter falls within the 1.00 mm to 2.00 mm reamer diameter range, making it appropriate for micro-bore finishing in molds, dies, medical components, and precision mechanical assemblies.\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\u003e1.22 mm reamer diameter with tolerance of 0.0000 to +0.0003 mm for tight bore control\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with left-hand spiral and right-hand cut reduces vibration and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eStraight shank seats directly in standard collet or drill chucks\u003c\/li\u003e\n  \u003cli\u003e50 mm overall length with 10 mm flute length suited to shallow precision bores\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or equivalent chucking reamer for applications requiring a 1.22 mm straight-shank solid carbide spiral-flute reamer in standard collet and drill chuck tooling systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this reamer should be performed by qualified machinists familiar with small-diameter carbide tooling. Secure the straight shank fully and concentrically in the chuck before operation to prevent runout that can chip carbide flutes. Use appropriate cutting fluid for the workpiece material and ensure the pre-drilled pilot hole is sized correctly for the material allowance before reaming. Handle carbide tooling with care to avoid chipping the cutting edges during storage and setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1.22 mm (0.0480 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: 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 Range\u003c\/strong\u003e: 1.00 mm to 2.00 mm\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: MR34-0480.406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748823859506,"sku":"MR34-0480.406","price":110.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d7e36790b58ea245b3c5b516bc3b24a.jpg?v=1788899046","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0480-406-chucking-reamer-1-22mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
