With a reamer diameter of 0.077 inches and a diameter tolerance of 0.0000 to 0.0002 inches, this tool delivers consistent, repeatable bore sizing where accuracy is critical. The bright, uncoated solid carbide construction provides rigidity and wear resistance across a range of workpiece materials. At 1-3\/4 inches overall length with a 1\/2-inch flute length, it is sized for shallow-bore reaming operations on CNC machines, lathes, and drill presses equipped with standard straight-shank toolholding systems. A 4-flute configuration supports stable cutting action and smooth surface finish.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for light industrial and precision machining environments requiring sub-0.1-inch bore finishing. Typical applications include close-tolerance hole sizing in metal components where drill-only finishes are insufficient. The straight flute geometry and right-hand cutting direction make it compatible with conventional spindle rotation. It is appropriate for use in job shops, tool rooms, and production machining cells where consistent hole geometry and surface quality are required on small-diameter bores.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in precision boring\u003c\/li\u003e\n\u003cli\u003eReamer diameter of 0.077 inches with a tight tolerance of 0.0000 to 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e4-flute straight configuration for stable cutting and smooth bore finish\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for a broad range of ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for secure seating in standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for use with conventional CNC and manual spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide chucking reamer for use in standard straight-shank toolholders and collet systems accommodating small-diameter reaming tools in the 0.0500 to 0.0999-inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis reamer is installed by machinists in CNC machining centers, lathes, or drill presses using a collet or drill chuck rated for the straight cylindrical shank diameter. Always ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout at the spindle before reaming to avoid oversizing the bore. Feed rate and spindle speed should be selected based on workpiece material and machine capability; consult published carbide tooling guidelines for the specific material being reamed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.077 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0002 inches\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 79889077\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728630382898,"sku":"79889077","price":59.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b13d5a5c43890b494c34d76a41f4f0e.jpg?v=1788694182","url":"https:\/\/voomisupply.com\/products\/hertel-79889077-chucking-reamer-0-077-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
