Solid carbide construction provides the rigidity and wear resistance required for tight-tolerance work in hardened steels, cast iron, aluminum, and similar materials. The spiral flute geometry — with a left-hand spiral and right-hand cut — promotes smooth chip evacuation and reduces chatter during through-hole reaming. With a 10 mm flute length and a 50 mm overall length, this tool is sized for small-bore work where dimensional accuracy is critical. It is used by machinists and toolroom technicians in CNC and manual machine applications.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for precision hole-finishing operations in machine shops, tool-and-die environments, and production floor settings. The straight shank mounts directly into standard collet chucks, drill chucks, or reamer holders. With a diameter tolerance of 0.0000 to +0.0003 mm, it is appropriate for close-fit applications such as dowel pin holes, bearing bores, and hydraulic component passages where finish and size are held to tight specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in abrasive and hardened materials\u003c\/li\u003e\n\u003cli\u003eLeft-hand spiral flute with right-hand cut for smooth chip flow and reduced chatter\u003c\/li\u003e\n\u003cli\u003e1.63 mm reaming diameter with a tolerance of 0.0000 to +0.0003 mm for precision hole sizing\u003c\/li\u003e\n\u003cli\u003e4 flutes for consistent surface finish and stable cutting geometry\u003c\/li\u003e\n\u003cli\u003eStraight shank for compatibility with standard collet chucks and reamer holders\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup that could affect final hole diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a straight-shank chucking reamer for use in CNC machining centers, manual mills, and drill presses equipped with collet chucks or drill chucks accepting a straight shank in the 1.63 mm diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists and toolroom technicians. Secure the straight shank firmly in a collet chuck or reamer holder before use, and verify runout with an indicator prior to cutting. Machine the pilot hole to the correct pre-ream diameter before running the reamer — never use a chucking reamer to remove excessive stock. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1.63 mm (0.0642 inches)\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\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 to +0.0003 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 1.00 mm to 2.00 mm class\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: MR34-0642.406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752372011314,"sku":"MR34-0642.406","price":110.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e7d542926622e5dd474564b40301651.jpg?v=1788927753","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0642-406-chucking-reamer-1-63mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
