With a 1\/2 inch diameter and a tight diameter tolerance of 0.0000 to 0.0003 inches, this reamer delivers consistent, accurate bore sizing in production and job-shop environments. The straight flute geometry and right-hand cut configuration make it well suited for through-hole and blind-hole reaming in a wide range of ferrous and non-ferrous materials. Machinists and toolroom professionals install this reamer in CNC machining centers, lathes, and drill presses using a standard chuck or collet.\u003c\/p\u003e\u003cp\u003eThis reamer is applied in machining operations that require close-tolerance hole finishing where drilled holes must be brought to a precise final diameter. The 1-1\/2 inch flute length provides adequate chip clearance for typical production reaming depths, while the 4 inch overall length gives sufficient reach for most standard workpiece setups. The straight cylindrical shank allows direct chuck mounting without the need for specialized toolholders, making setup fast and straightforward in both manual and CNC machine tool applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life and superior wear resistance compared to high-speed steel\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of 0.0000 to 0.0003 inches for precise, repeatable bore sizing\u003c\/li\u003e\n\u003cli\u003e6-flute straight flute design promotes smooth cutting action and consistent surface finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for direct chuck or collet mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide chucking reamer for machine tool applications requiring a 1\/2 inch nominal diameter, straight flute, straight shank reamer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Secure the straight shank firmly in a chuck or collet rated for the spindle speed being used, and verify runout before beginning the reaming operation. Always power down and lock out the machine spindle before changing or inspecting tooling. Use an appropriate cutting fluid for the workpiece material to promote tool life and achieve the specified bore tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/2 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: 0.5 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: 79890372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51753011413298,"sku":"79890372","price":224.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51037f482b69ab3f2a462e726d18d9f8.jpg?v=1788932117","url":"https:\/\/voomisupply.com\/products\/hertel-79890372-chucking-reamer-1-2-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
