With a 0.9850-inch diameter and an overall length of 10.5 inches, this reamer delivers accurate, smooth bores in ferrous and non-ferrous metals. The straight flute geometry and bright uncoated finish make it well suited to through-hole reaming operations where chip evacuation and surface finish consistency are the primary requirements. Eight flutes provide a stable cutting action across the full 2.75-inch flute length. The straight-cylindrical shank allows direct mounting in standard machine chucks or collet holders. This tool is intended for installation in drill presses, lathes, machining centers, or turret lathes operated by machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThe 72039852 is applied in production and toolroom environments where bore tolerance and surface finish must meet close specifications. Typical use cases include finishing drilled or bored holes to a nominal 0.9850-inch diameter in materials such as mild steel, aluminum, brass, and cast iron. The right-hand cutting direction is standard for conventional spindle rotation. The 10.5-inch overall length accommodates deeper reach requirements compared to shorter jobber-style reamers, making it useful in setups where spindle-to-workpiece clearance is limited.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.9850-inch finished-bore diameter for close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003eHSS construction provides toughness across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e8 straight flutes deliver consistent surface finish and stable cutting action\u003c\/li\u003e\n\u003cli\u003e2.75-inch flute length suited to moderate-depth through-hole applications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — compatible with a wide range of cutting fluids\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in drill presses, lathes, machining centers, and turret lathes equipped with chucks or collet holders sized for a straight-cylindrical shank in the 0.9850-inch diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists familiar with rotating cutting tool safety practices. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet to minimize runout. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish; dry reaming is not recommended for most metals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.9850 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.75 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\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: 0.27 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: 72039852\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51751560905010,"sku":"72039852","price":320.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fc07a3f2d86a138c3d009f6312ade95b_622137af-b88b-4af4-89bf-203ee433e68e.jpg?v=1788923809","url":"https:\/\/voomisupply.com\/products\/hertel-72039852-chucking-reamer-0-9850-in-hss-8-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
