Built from solid carbide, it delivers the rigidity and edge retention needed for accurate hole sizing in ferrous and non-ferrous materials. The 0.44 inch diameter reamer holds a tight tolerance of 0.0000 to 0.0003 inches over nominal, making it suitable for applications where fit and finish are critical. At 4 inches overall length with a 1-3\/8 inch flute length, this tool fits standard drill press and CNC machining center setups. Machinists and toolroom operators rely on this style of reamer for production and maintenance work requiring repeatable hole geometry.\u003c\/p\u003e\u003cp\u003eThis reamer is intended for machine-tool use in shop environments where close-tolerance hole finishing is required. The straight cylindrical shank accepts standard chucks and collets on drill presses, lathes, and machining centers. The 6-flute, straight-flute geometry suits through-hole and short blind-hole reaming in a range of workpiece materials. It is sold individually and is appropriate for both production runs and job-shop applications where dimensional accuracy of the finished bore is a primary concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and edge retention compared to high-speed steel\u003c\/li\u003e\n\u003cli\u003e0.44 inch nominal diameter with a tolerance of 0.0000 to 0.0003 inches over nominal\u003c\/li\u003e\n\u003cli\u003e6-flute straight-flute design for consistent stock removal and smooth bore finish\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — ready to use as supplied, no additional prep required\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for direct chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; compatible with standard machine spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a machine chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with a chuck or collet capable of accepting a straight cylindrical shank.

Ensure the machine spindle is fully stopped and the tool is securely clamped in the chuck or collet before starting the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Inspect the reamer for edge chipping before each use — carbide tooling is brittle and should not be used if the cutting edges show damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.44 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: 1-3\/8 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\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 over nominal\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: 0.24 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: 79890075\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733447573810,"sku":"79890075","price":260.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37255143d892486c284549854bf4f304.jpg?v=1788755535","url":"https:\/\/voomisupply.com\/products\/hertel-79890075-chucking-reamer-0-44-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
