Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in metalworking applications. The straight-cylindrical shank mounts directly in a drill chuck or collet holder without modification. With 6 flutes and a right-hand cutting direction, this reamer produces smooth, tight-tolerance bores in a single pass. Overall length is 4-7\/8 inches with a 1-3\/4 inch flute length, making it suited for short-to-medium depth holes in production and maintenance machining environments.\u003c\/p\u003e\u003cp\u003eThis reamer is used in machine shop, toolroom, and maintenance repair operations where hole size must meet close-tolerance fit requirements. It is appropriate for use in drill presses, lathes, and CNC machining centers with a compatible straight-shank chuck or collet. Typical applications include reaming clearance holes, bearing seats, and pin-fit bores in ferrous and non-ferrous materials. Machinists and tool-and-die technicians are the primary users of this type of reamer.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter S diameter (0.3480 inches) for precise hole sizing within the 0.3000 to 0.3499 inch range\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e6 straight flutes with right-hand cutting direction for smooth, accurate bore finishing\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct chuck or collet mounting without adapters\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional tolerance\u003c\/li\u003e\n\u003cli\u003eCompact 4-7\/8 inch OAL suits standard drill press and lathe setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard toolroom chucking reamer for use in any drill press, lathe, or machining center equipped with a straight-shank chuck or collet sized to accept a 0.3480-inch shank tool.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or trained toolroom technician should install and operate this reamer. Ensure the machine spindle is fully stopped and the workpiece is securely fixtured before mounting the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Do not exceed the recommended feed rate for HSS reamers in hard or abrasive materials, as overfeeding will cause premature edge wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Letter)\u003c\/strong\u003e: S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.3480 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.3000 to 0.3499 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-3\/4 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\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\u003eDowel Pin Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 72292196\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747513237810,"sku":"72292196","price":62.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d2b47a4a40697adb4b82fadea9aa6c7_2aaee97e-a371-4e39-a93c-674951089af8.jpg?v=1788881660","url":"https:\/\/voomisupply.com\/products\/hertel-72292196-chucking-reamer-letter-s-hss-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
