Manufactured from cobalt high-speed steel, it delivers improved heat and wear resistance compared to standard M2 HSS tooling. The cutter measures 1 inch in diameter with a 3 inch length of cut, a 1 inch shank diameter, and a 5-1\/2 inch overall length. The 30-degree helix angle and coarse pitch flute geometry promote efficient chip evacuation and reduce cutting forces during slotting, peripheral milling, and profiling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in manual knee mills, CNC machining centers, and horizontal milling setups where a full-inch diameter cutter is required. The uncoated cobalt construction makes it a practical choice for regrinding after wear, extending tool life across production and maintenance shop environments. Right-hand cut and right-hand flute orientation are standard for conventional milling machine spindles. It fits applications in job shops, maintenance facilities, and production floors working with steel, stainless, cast iron, and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt HSS construction for improved heat resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003e5-flute design increases feed rates and improves surface finish versus 4-flute geometry\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle supports efficient chip flow in slotting and profiling cuts\u003c\/li\u003e\n\u003cli\u003eUncoated finish allows straightforward regrinding to restore cutting edge\u003c\/li\u003e\n\u003cli\u003eCoarse pitch flute spacing reduces chatter and vibration in interrupted cuts\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard milling spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1 inch shank square end mill compatible with ER and CAT toolholders, collet chucks, and end mill holders sized for a 1 inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and locked out per applicable machine safety procedures. Ensure the toolholder and collet are clean and free of chips before seating the shank to the full depth recommended by the holder manufacturer. Verify runout with a dial indicator before commencing cuts, as excessive runout accelerates edge wear and reduces surface finish quality. Cutting speeds and feeds should be selected based on workpiece material, machine rigidity, and depth of cut using standard machining data references.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 5-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 490\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 4910700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51735191617842,"sku":"4910700","price":281.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b460e180ca5daaf44ba71bd9aa1508d2.jpg?v=1788770165","url":"https:\/\/voomisupply.com\/products\/osg-4910700-square-end-mill-1-in-5-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
