Built with a straight flute geometry and a straight cylindrical shank, this reamer delivers a right-hand cutting action that produces accurate, smooth-bore holes in a range of materials. The 0.066-inch diameter is held to a tight tolerance of 0.0000 to 0.0002 inches over nominal, making it well suited for close-tolerance work where bore quality is critical. Four flutes provide stable cutting performance and consistent chip evacuation throughout the reaming stroke. The bright, uncoated carbide surface is appropriate for dry or light-lubricated cutting conditions.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is intended for use in CNC machining centers, manual knee mills, drill presses, and similar machine tool setups where the reamer is held in a chuck or collet. Its 0.066-inch diameter and 1.75-inch overall length make it a practical choice for small-diameter precision reaming in metalworking, toolroom, and production environments. A qualified machinist or toolroom operator typically selects this tool for finishing pre-drilled or bored holes that require tight dimensional control.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in small-diameter reaming\u003c\/li\u003e\n\u003cli\u003eFour straight flutes with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of 0.0000 to 0.0002 inches over nominal for precise bore sizing\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for secure chuck or collet retention\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose reaming applications\u003c\/li\u003e\n\u003cli\u003eCompact 1.75-inch overall length with 0.5-inch flute length for shallow-hole work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose chucking reamer for machine tool applications requiring a 0.066-inch finished bore diameter with a straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis reamer is installed by a machinist and held in a chuck or collet sized to match the straight cylindrical shank. Ensure the workpiece is rigidly fixtured and the pre-drilled hole is undersized per standard reaming allowance before use. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not attempt to correct a significantly misaligned or oversized hole with a chucking reamer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.066 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0002 inches over nominal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5 inches\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: Straight\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 Cylindrical\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: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\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: 79889002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749883412786,"sku":"79889002","price":63.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca3a92cd8e688907b453f7b4a8092a4c.jpg?v=1788911690","url":"https:\/\/voomisupply.com\/products\/hertel-79889002-chucking-reamer-0-066-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
