Built from cobalt steel, it resists heat and wear better than standard high-speed steel, making it well-suited for harder workpiece materials and higher-speed operations. The straight flute geometry produces clean, accurate bores with predictable chip evacuation. At 5 inches overall length with a 1-1\/4 inch flute length and a straight-cylindrical shank, it mounts directly in a drill chuck or collet for use in drill presses, lathes, and CNC machining centers. The bright, uncoated finish allows for easy wear inspection. Machinists and tool-and-die professionals install this reamer to bring drilled holes to final dimensional tolerance.\u003c\/p\u003e\n\u003cp\u003eThis reamer is intended for right-hand cutting in production and maintenance machining environments where Wire Size No. 3 holes must meet tight dimensional requirements. Typical applications include fixture and jig work, dowel-hole finishing, and precision bore sizing in ferrous and non-ferrous metals. The straight-cylindrical shank accepts standard collets and drill chucks without adapters, keeping setup time low in both manual and CNC setups. It is not configured as a dowel pin reamer and is not an over- or under-size variant, so it cuts to the nominal 0.2130 inch diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt steel construction for improved heat resistance and tool life over standard HSS\u003c\/li\u003e\n  \u003cli\u003e0.2130 inch cutting diameter — Wire Size No. 3, falling in the 0.2000 to 0.2499 inch range\u003c\/li\u003e\n  \u003cli\u003eStraight flute geometry for clean chip evacuation and consistent bore finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets without adapters\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup to mask wear or affect tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style wire-size chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a drill chuck or straight-shank collet in the appropriate size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist familiar with reaming procedures and machine tool operation. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation, and verify runout is within acceptable limits to avoid oversize bores. Always reduce spindle speed relative to drilling and apply cutting fluid appropriate for the workpiece material when reaming. Never attempt to use a reamer to remove excessive stock — pre-drill or bore the hole to within a few thousandths of final size before reaming.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2130 inches (Wire Size No. 3)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.2000 to 0.2499 inches (5.00 to 6.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eTool Material\u003c\/strong\u003e: Cobalt Steel\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 72308034\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755748000050,"sku":"72308034","price":42.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72e2e18333df4a003c3e2e1b8f028578_ab532806-6b0d-4716-80ab-f97c84907c52.jpg?v=1788959098","url":"https:\/\/voomisupply.com\/products\/hertel-72308034-chucking-reamer-wire-3-0-2130-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
