Built with a 0.65 mm reamer diameter and a right-hand cutting direction, it delivers controlled, repeatable material removal in pre-drilled holes. The left-hand spiral flute geometry helps evacuate chips effectively during the cut. With a reamer diameter tolerance of 0.0000 to +0.0003 mm, this tool is suited for applications where bore accuracy is critical. Machinists and tool-and-die professionals use this reamer in CNC machining centers, drill presses, and manual lathes equipped with a collet or drill chuck.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is intended for use in precision machining environments where small-diameter bores require a high degree of dimensional accuracy. The straight shank allows it to seat securely in standard collet chucks and drill chucks across a range of machine tool setups. At 50 mm overall length with a 7 mm flute length, this tool is sized for shallow, fine-diameter finishing passes. It is sold individually and is suited for production machining, toolroom work, and repair applications requiring sub-millimeter bore finishing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.65 mm reamer diameter with a tight tolerance of 0.0000 to +0.0003 mm for precision bore finishing\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003eLeft-hand spiral flute geometry promotes chip evacuation during right-hand cutting\u003c\/li\u003e\n\u003cli\u003e4 flutes provide a balanced cutting action and smooth surface finish\u003c\/li\u003e\n\u003cli\u003eStraight shank for compatibility with standard collet and drill chuck toolholding\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — no coating buildup risk in tight-tolerance bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in CNC machining centers, drill presses, and lathes accepting straight-shank tooling in the sub-1 mm diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis reamer should be installed by a qualified machinist following standard toolroom practices. Ensure the machine spindle is fully stopped and locked out before securing or removing the tool from the chuck. Use a correctly sized collet or drill chuck to grip the straight shank without runout. Always pre-drill the bore to the appropriate pilot diameter before reaming — do not use a chucking reamer to remove excess stock.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.65 mm (0.0256 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 50 mm (1.9685 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7 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 Tolerance\u003c\/strong\u003e: 0.0000 to +0.0003 mm\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: MR34-0256.281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748297441586,"sku":"MR34-0256.281","price":89.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3693dbd47c22a1a0f8398916e4888856.jpg?v=1788891982","url":"https:\/\/voomisupply.com\/products\/hertel-mr34-0256-281-chucking-reamer-0-65mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
