It features a 1-inch cutting diameter, a 3-inch length of cut (LOC), and a 1-inch shank diameter, making it a heavy-duty tool suited for full-slot and peripheral milling applications. The 5-flute configuration increases the number of cutting edges over standard 4-flute designs, which improves feed rates and surface finish in finish and semi-finish passes. Overall length is 5.5 inches. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. This tool is uncoated cobalt construction and is intended for use by machinists and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal milling machines, VMCs, and manual knee mills where a full 1-inch diameter cut is required. The fine-pitch flute spacing and right-hand cut with right-hand flute orientation make it appropriate for conventional and climb milling in steel, stainless steel, cast iron, and similar materials. The regular-length geometry suits standard fixturing without requiring extended-reach toolholders. It is a single-end tool, so it is replaced rather than re-indexed when worn.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-flute design supports higher feed rates and improved surface finish versus 4-flute end mills\u003c\/li\u003e\n\u003cli\u003eCobalt construction provides heat resistance for cutting ferrous and hard alloy materials\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle aids chip evacuation and reduces axial cutting forces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute orientation for standard milling spindle use\u003c\/li\u003e\n\u003cli\u003eUncoated finish — suitable for re-sharpening by a qualified tool grinding service\u003c\/li\u003e\n\u003cli\u003e1-inch shank diameter compatible with standard ER, Weldon, and shrink-fit toolholders sized for 1-inch shanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool for milling applications requiring a 1-inch diameter square end mill with a 1-inch shank.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm shank engagement depth meets the toolholder minimum insertion requirement before tightening. Inspect the cutting edges and shank for damage before each use.\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: 5.5 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\u003eCutting 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\u003ePitch\u003c\/strong\u003e: Fine\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: 4510700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748494377266,"sku":"4510700","price":295.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7823a788deb99bacf8aa6fabe8e921bf.jpg?v=1788894431","url":"https:\/\/voomisupply.com\/products\/osg-4510700-square-end-mill-1-in-cobalt-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
