With an overall length of 9 inches and a straight-cylindrical shank, it is built for use in machine spindles and drill press chucks where controlled, repeatable bore sizing is required. The 8-flute, right-hand cutting configuration with a straight flute geometry promotes smooth material removal and a fine surface finish in the reamed bore. The bright, uncoated finish is standard for general-purpose HSS reamers. This tool is used by machinists and toolroom technicians working in production and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for finish-reaming operations in metalworking applications where close-tolerance hole sizing is needed. The 2.25-inch flute length accommodates typical bore depths encountered in machine components, fixtures, and mechanical assemblies. The straight-cylindrical shank allows direct mounting in standard drill chucks, collets, or floating reamer holders on lathes, drill presses, and CNC machining centers. Its right-hand cutting direction is compatible with conventional clockwise spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.6390-inch finished bore diameter for close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003e8 straight flutes with right-hand cutting direction for smooth stock removal\u003c\/li\u003e\n\u003cli\u003e9-inch overall length with a 2.25-inch flute length\u003c\/li\u003e\n\u003cli\u003eHSS construction offers toughness across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — standard for general-purpose reaming applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks, collets, and floating holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose chucking reamer for use in standard drill chucks, collets, and floating reamer holders on lathes, drill presses, and machining centers that accept a straight-cylindrical shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed and operated by machinists using appropriate machine tooling and work-holding equipment. Ensure the spindle and workpiece are securely fixtured before reaming. Always bring the reamer into the pre-drilled pilot hole with the spindle running at the correct speed and feed for the workpiece material — never rotate a reamer in reverse, as this dulls the cutting edges. Use appropriate cutting fluid to extend tool life and achieve the target surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.6390 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 8\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: HSS (High-Speed Steel)\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: 0.23 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: 72036395\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736513380658,"sku":"72036395","price":151.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27f7c4490510e6f20e880c37731f0b81_e600854c-2072-47c3-a5a9-d327a99d745b.jpg?v=1788778356","url":"https:\/\/voomisupply.com\/products\/hertel-72036395-chucking-reamer-0-6390-in-hss-8-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
