Built with a straight flute geometry and a straight cylindrical shank, it delivers consistent sizing performance in drilling and boring operations. The reamer measures 0.31 inches in diameter with an overall length of 3.25 inches and a flute length of 1.125 inches. Solid carbide construction provides the rigidity and wear resistance needed for tight-tolerance work in ferrous and non-ferrous materials. With a right-hand cutting direction and a diameter tolerance of 0.0000 to 0.0003 inches, this reamer is suited for applications where bore accuracy is critical.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is used in CNC machining centers, drill presses, and manual lathes across metalworking and tooling shops. It is appropriate for finishing pre-drilled or bored holes to precise diameters in production and maintenance machining environments. The bright, uncoated finish makes it a straightforward choice for general-purpose reaming where coating is not required. Machinists, toolroom technicians, and production machine operators are the primary users of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in precision reaming\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of 0.0000 to 0.0003 inches for tight-tolerance bore finishing\u003c\/li\u003e\n\u003cli\u003eStraight flute design with 6 flutes for smooth cutting action\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, straight cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose metalworking applications\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 3.25 inches for use in confined setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style chucking reamer for use in standard straight-shank tool holders and drill chucks on CNC machining centers, drill presses, and lathes requiring a 0.31-inch finished bore diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eChucking reamers are installed and operated by machinists and toolroom technicians. Ensure the workpiece is securely fixtured and the reamer is properly aligned with the pre-drilled hole before operation to avoid chatter or tool deflection. Use appropriate cutting fluid for the workpiece material to prolong tool life and maintain surface finish quality. Inspect the reamer for chipping or wear before each use, as carbide tooling can be brittle if mishandled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 to 0.0003 inches\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: 79890000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732457423154,"sku":"79890000","price":119.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9353ba527ceb55f57c1ae2ff559466bf.jpg?v=1788742976","url":"https:\/\/voomisupply.com\/products\/hertel-79890000-chucking-reamer-0-31-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
