Built to Series 2045 specifications, it features a 3\/8 inch cutting diameter, a 1 inch length of cut, and a 37-degree medium helix angle that promotes efficient chip evacuation and smooth cutting action. The NF1 PVD coating enhances wear resistance and is optimized for non-ferrous metals as the primary workpiece material. With a submicron carbide grade and three spiral flutes, this tool delivers precise material removal in a compact, single-end configuration. Licensed machinists and CNC operators are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThe GWS 315250 is suited for milling non-ferrous metals such as aluminum and copper alloys, as well as cast iron, superalloys, and titanium in secondary applications. It fits standard machining centers and CNC mills using a 3\/8 inch straight-cylindrical shank with h6 tolerance. The 2.5 inch overall length makes it a practical choice for general-purpose contouring, profiling, and slot milling where a ball-nose geometry is required. It is rated for both roughing and finishing passes, reducing the need for tool changes during a single operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with submicron material grade for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eNF1 PVD coating optimized for non-ferrous metals, cast iron, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e37-degree medium helix angle for efficient chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eThree spiral flutes in a right-hand cut, right-hand flute configuration\u003c\/li\u003e\n  \u003cli\u003eBall nose geometry with a 0.1875 inch nose radius for contour and profile work\u003c\/li\u003e\n  \u003cli\u003eSingle-end design rated for both roughing and finishing operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills with a standard 3\/8 inch straight-cylindrical collet or toolholder.

Secure the straight-cylindrical shank in a properly sized collet or end mill holder torqued to the toolholder manufacturer's specification. Verify runout with a dial indicator before initiating a cut, as excessive runout accelerates wear on carbide tooling. Consult the machine manufacturer's feed and speed recommendations for the specific workpiece material before beginning the operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical, h6 tolerance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees (Medium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: NF1 (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron; Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2045\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\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: GWS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 315250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51994990248242,"sku":"315250","price":124.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/478a499f33539701805898ad22fd2a84.jpg?v=1789992378","url":"https:\/\/voomisupply.com\/products\/gws-315250-ball-end-mill-3-8-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
