Built from cobalt steel, this reamer delivers the heat and wear resistance needed when working with tough alloys and harder ferrous materials. It produces a finished bore diameter of 0.1800 inches, corresponding to wire size 15, with an overall length of 4.5 inches and a flute length of 1.125 inches. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. The bright, uncoated finish maintains dimensional accuracy and allows easy inspection of cutting edge condition. Machinists, toolmakers, and CNC operators typically use this tool for accurate final sizing of drilled or bored holes.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for manual machine operations, turret lathes, drill presses, and CNC machining centers where a straight-flute reamer in the 0.1500 to 0.1999 inch diameter range is required. Right-hand cutting direction makes it compatible with standard right-hand spindle rotation. The compact overall length and straight shank simplify setup in tight work envelopes. It is not an over or under size reamer, meaning it is ground to the nominal 0.1800 inch dimension for standard tolerance hole finishing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt steel construction for improved heat resistance over standard high-speed steel\u003c\/li\u003e\n\u003cli\u003eStraight flute geometry for smooth cutting action in through-holes and blind holes with chip clearance\u003c\/li\u003e\n\u003cli\u003e0.1800 inch finished bore diameter, wire size 15\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank for direct chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for precise dimensional tolerances out of the box\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in drill presses, lathes, and machining centers accepting a straight-cylindrical shank tool in the 0.1500 to 0.1999 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified toolroom operator should install and operate this reamer using appropriate cutting fluid for the workpiece material. Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout with a dial indicator to prevent bell-mouthing or chatter. Always reduce feed rate and spindle speed relative to drilling operations; reaming typically runs at approximately one-half the drilling speed for the same material. Do not reverse spindle rotation while the reamer is engaged in the hole, as this will damage the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Wire Size)\u003c\/strong\u003e: 15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1800 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.1500 to 0.1999 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 72308158\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731310739762,"sku":"72308158","price":53.14,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72e2e18333df4a003c3e2e1b8f028578_da61eb62-ccb5-496d-974c-fa98bf6f0f5d.jpg?v=1788729599","url":"https:\/\/voomisupply.com\/products\/hertel-72308158-chucking-reamer-wire-size-15-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
