Built from high-speed steel (HSS) with a bright, uncoated finish, it is designed for precision hole finishing in machine shop and production environments. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With four right-hand flutes and an overall length of 2.75 inches, this reamer delivers clean, accurate bores in through-hole and shallow blind-hole applications where close dimensional tolerances are required.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for light production reaming on drill presses, CNC machining centers, turret lathes, and manual mills. It is intended for use on ferrous and non-ferrous metals, plastics, and similar machinable materials where a wire-gauge diameter hole must be finished to tight tolerances. The 0.875-inch flute length accommodates typical shallow-hole reaming depths common in fixture and component work. Machinists and toolroom technicians are the primary users of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 30 diameter: 0.1285 inches, within the 0.1000 to 0.1499 inch decimal range\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for durability across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose reaming applications\u003c\/li\u003e\n\u003cli\u003eFour straight right-hand flutes for consistent chip evacuation and smooth bore finish\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eCompact 2.75-inch overall length for use in confined setups and short-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard wire-gauge chucking reamer compatible with any machine spindle or chuck accepting a straight-cylindrical shank in the sub-0.15-inch diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of chucking reamers is performed by qualified machinists or toolroom technicians. Secure the shank fully in a drill chuck or collet before operation and verify runout with an indicator when tolerances are critical. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Power down the machine spindle completely before changing or inspecting the reamer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Gauge)\u003c\/strong\u003e: 30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1285 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.1000 to 0.1499 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: 0.1 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: 72290307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729217454386,"sku":"72290307","price":43.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c51c095728745ff1dc969ca3208c4fa6_f9956631-300c-44c8-a651-0f67cde98637.jpg?v=1788701992","url":"https:\/\/voomisupply.com\/products\/hertel-72290307-chucking-reamer-wire-size-30-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
