Ground from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate hole sizing in a wide range of ferrous and non-ferrous materials. It carries a 0.2040 inch cutting diameter, falls in the No. 6 wire gauge size range, and features 6 flutes with a right-hand cut for clean, consistent chip evacuation. Overall length is 5 inches with a 1.25 inch flute length. Machinists and tool-room technicians use this reamer in drill presses, lathes, and CNC machining centers where repeatable hole finish and dimensional accuracy are required.\u003c\/p\u003e\u003cp\u003eThis chucking reamer is suited for production and maintenance machining environments where wire-gauge-size holes must be brought to final dimension with minimal runout. The straight shank seats directly in standard drill chucks or collets without requiring a Morse taper adapter. The 6-flute geometry distributes cutting load evenly, reducing chatter in both through-hole and blind-hole applications on light to medium-duty setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.2040 inch cutting diameter corresponding to No. 6 wire gauge size\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e6 straight flutes with right-hand cut for controlled chip flow and smooth bore finish\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — ready to use as received or suitable for additional coating if required\u003c\/li\u003e\n\u003cli\u003eStraight shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003e5 inch overall length with 1.25 inch flute length for access in typical fixture setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with drill chucks or collet holders accepting a straight-shank tool.

Ensure the machine spindle is fully stopped and locked out before securing or changing the tool in the chuck or collet. Run at appropriate reamer speeds and feeds for the workpiece material — reamers require lower RPM and higher feed rates than drill bits to avoid chatter and premature edge wear. Never rotate a reamer in reverse, as this will dull the cutting edges immediately.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter\u003c\/strong\u003e: 0.2040 inches (No. 6 wire gauge)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReamer Diameter Range\u003c\/strong\u003e: 0.2000 to 0.2499 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (127 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches (31.75 mm)\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOver\/Under Size Reamer\u003c\/strong\u003e: No\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: C25404\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694110998834,"sku":"C25404","price":71.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd2d37f8324e6134ddc06512bc32ca54.jpg?v=1788320382","url":"https:\/\/voomisupply.com\/products\/cleveland-c25404-chucking-reamer-0-2040-in-hss-straight","provider":"Voomi Supply","version":"1.0","type":"link"}
