With a 0.0591-inch cutting diameter and four flutes cut in a right-hand, 35-degree helix, this end mill delivers clean, efficient material removal in hardened and difficult-to-cut materials. The WXL coating improves wear resistance and extends tool life in demanding cutting conditions. A micrograin carbide substrate provides the rigidity and edge retention needed for tight-tolerance work. This tool is intended for use by machinists and CNC operators in job shop, toolroom, and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for small-feature milling operations where a compact cutting diameter and extended reach are required. The 0.0906-inch length of cut and 0.1575-inch shank diameter allow it to reach into confined areas while maintaining shank rigidity. The extended reach design makes it appropriate for deep-pocket or stepped-bore applications in ferrous and non-ferrous workpiece materials. It is installed as a single-end tool in standard CNC machining centers or manual milling machines equipped with a compatible collet or tool holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0591-inch cutting diameter with 0.0906-inch length of cut for small-feature precision milling\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand cut and right-hand flute geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e35-degree helix angle reduces cutting forces and improves surface finish\u003c\/li\u003e\n\u003cli\u003eWXL coating provides enhanced wear resistance in high-performance cutting conditions\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and extended edge retention\u003c\/li\u003e\n\u003cli\u003eExtended reach design for deep-pocket and confined-area milling\u003c\/li\u003e\n\u003cli\u003eCentercutting capable, allowing plunge entry into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills using a 0.1575-inch (4.00 mm) shank collet or tool holder.

Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before loading or removing the end mill. Seat the shank fully in a clean, undamaged collet to the recommended engagement depth and torque the collet nut per the tool holder manufacturer specification. Inspect the cutting edges for chips or damage before each use, and confirm proper runout with a dial indicator prior to production cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0591 inches (1.5 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0906 inches (2.3 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1575 inches (4.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 45 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 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 Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WXL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.55 x 0.55 x 0.45 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: 3172508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744584139058,"sku":"3172508","price":117.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68f5aa371fe72f635f7042f9adad44a1_c49e50da-c9a8-4461-a1d9-6cbc5396ce81.jpg?v=1788858618","url":"https:\/\/voomisupply.com\/products\/osg-3172508-square-end-mill-0-0591-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
