It features a 0.0591-inch (1.5 mm) cutting diameter and four flutes with a 35-degree helix angle, producing clean, accurate cuts at small-diameter scales. The WXL coating provides wear resistance and extended tool life in demanding machining environments. At 0.0906 inches (2.3 mm) length of cut and a 0.1575-inch (4.0 mm) shank diameter, this tool is built for tight-tolerance work in CNC machining centers. Micrograin carbide construction supports high-speed feeds and minimizes deflection at this diameter range. Machinists and toolroom operators working in precision and prototype environments are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish milling, slotting, and profiling operations at small feature scales. The extended reach design allows access to recessed features and deep-wall pockets within its cutting envelope. Right-hand cut with right-hand flute direction matches standard CNC spindle rotation. Its length-of-cut range covers 0.0000 to 0.1000 inches, making it appropriate for shallow-to-moderate depth passes in precision machining applications including mold, die, and medical component work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0591-inch (1.5 mm) cutting diameter for precision small-feature milling\u003c\/li\u003e\n\u003cli\u003e4-flute geometry with 35-degree helix angle for smooth chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eWXL coating for enhanced wear resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction reduces deflection at small diameters\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — suitable for plunge entry\u003c\/li\u003e\n\u003cli\u003eExtended reach design for access to recessed features and deeper pockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or toolroom addition for CNC machining centers and manual mills using a 0.1575-inch (4.0 mm) shank diameter collet or tool holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully and evenly in a clean, properly sized collet or end mill holder to the recommended grip length — avoid gripping on the fluted section. Verify runout with a dial indicator before commencing a cut, as excessive runout at this diameter will accelerate tool wear and reduce surface finish quality.\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\u003eLength of Cut Range\u003c\/strong\u003e: 0.0000 to 0.1000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1575 inches (4.0 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 45 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\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\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\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 Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 3172506\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737059426610,"sku":"3172506","price":117.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68f5aa371fe72f635f7042f9adad44a1_5ccf85bd-9c50-418d-b63b-c5348f45327a.jpg?v=1788783732","url":"https:\/\/voomisupply.com\/products\/osg-3172506-square-end-mill-0-0591-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
