With a nominal cutting diameter of 0.187 inches and a bright, uncoated finish, this reamer is built for machine use in drill presses, lathes, and milling setups where repeatable hole tolerance is required. The six-flute straight configuration promotes smooth chip evacuation and consistent surface finish. At 4.5 inches overall length with a 1.125-inch flute length, it fits standard chucks without adaptation.\u003c\/p\u003e\u003cp\u003eThis reamer is classified as a dowel pin reamer, ground to a 0.1870-inch diameter with a tolerance of 0.0000 to -0.0020 inches — making it appropriate for locating pin holes and precision assembly applications where close fits are critical. It is suited for use on ferrous and non-ferrous metals in general machining, toolmaking, and maintenance environments. The straight shank seats directly into drill chucks or collets with no taper adapter required. Right-hand cutting direction is standard for conventional spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDowel pin reamer ground to 0.1870-inch diameter with tolerance of 0.0000 to -0.0020 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eSix straight flutes for smooth cutting action and consistent hole finish\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides wear resistance across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup that could affect dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eStraight shank accepts standard drill chucks and collets directly\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with conventional machine spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style machine reamer for use in drill presses, lathes, and milling machines requiring a 0.187-inch finished hole diameter with dowel pin tolerance.

Always power down and lock out the machine spindle before loading or removing the reamer. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Avoid hand-turning a machine reamer backward, as reverse rotation can chip the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.187 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\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\u003eShank 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\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: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDowel Pin Tolerance\u003c\/strong\u003e: 0.0000 to -0.0020 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C25365\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699824558386,"sku":"C25365","price":70.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1c9ec8b37df381f8324b5e6259dc2b2.jpg?v=1788381605","url":"https:\/\/voomisupply.com\/products\/cleveland-c25365-chucking-reamer-0-187-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
