It produces a 0.2510 inch finished bore diameter with a right-hand cutting direction. The flute length runs 2.465 inches, the overall length is 4 inches, and the cylindrical shank diameter is 0.2510 inches. The bright uncoated finish is suited for use in a range of workpiece materials where coating adhesion or heat buildup is not a primary concern. This tool is used by machinists and CNC operators in metalworking and precision machining environments.\u003c\/p\u003e\n\u003cp\u003eThe 257-2510 is intended for applications requiring close-tolerance hole finishing immediately after drilling. It is well suited to production environments running moderate to high volumes of precision bores in ferrous and non-ferrous materials. The single-pass drill-and-ream action makes it a practical choice for CNC machining centers and drill presses where tool changes reduce throughput. It is packaged individually and sold in single-unit quantities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombo drill-and-ream geometry completes hole drilling and finishing in one operation\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance compared to HSS alternatives\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eCylindrical shank fits standard collets and drill chucks sized for 0.2510 inch shanks\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCompact 4 inch overall length supports use in confined setups or short-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or production combo drill reamer for CNC machining centers, drill presses, and similar equipment accepting cylindrical shank tooling with a 0.2510 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with rotating cutting tool setup. Secure the cylindrical shank in a properly sized collet or chuck and verify runout before cutting. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Follow the machine manufacturer guidelines for feed rate and spindle speed appropriate to the workpiece material and tool diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReamer Size\u003c\/strong\u003e: 0.2510 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.465 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2510 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.15 inches L x 0.45 inches W x 0.35 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241611\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 257-2510\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732160577842,"sku":"257-2510","price":241.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c2733ff152466449c482c84cb81953b.jpg?v=1788739870","url":"https:\/\/voomisupply.com\/products\/osg-257-2510-combo-drill-reamer-0-2510-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
