Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this four-flute tool delivers accurate sizing in light-to-medium finishing operations. The straight-cylindrical shank seats directly in a drill chuck or collet holder, and the straight flute geometry suits through-hole reaming in a range of ferrous and non-ferrous materials. At 2.75 inches overall length with a 0.875 inch flute length, this reamer is suited for short, precise bores in production or toolroom environments. Machinists, tool and die makers, and maintenance technicians are the primary users.\u003c\/p\u003e\u003cp\u003eThis reamer is intended for use in machine tool applications where hole tolerance and surface finish are critical. It performs best when mounted in a rigid spindle on a drill press, mill, or lathe tailstock. Typical applications include finish-reaming pilot holes, dowel pin holes, and close-tolerance bores in jigs, fixtures, and machine components. The small diameter and compact flute length make it well suited for precision work in tight geometries. Right-hand cutting direction is standard and compatible with conventional spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 31 diameter — 0.1200 inch for close-tolerance hole finishing\u003c\/li\u003e\n\u003cli\u003e4-flute straight configuration for smooth material removal and clean bore finish\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction provides hardness and wear resistance across common workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct chuck or collet mounting without adapters\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction matches 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, milling machines, lathes, and CNC machining centers equipped with a drill chuck or collet capable of gripping a straight-cylindrical shank at this diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before mounting or removing the reamer. Seat the straight-cylindrical shank fully in the chuck or collet and verify runout before cutting. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish; avoid running the reamer dry in steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: 31\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.1000 - 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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: 72290315\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728225173810,"sku":"72290315","price":38.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c51c095728745ff1dc969ca3208c4fa6_8eafb80c-005f-4a96-803e-df2bd072065e.jpg?v=1788689858","url":"https:\/\/voomisupply.com\/products\/hertel-72290315-chucking-reamer-wire-size-31-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
