It features a 1\/2 inch diameter with a 0.0150 inch corner radius, a 1-1\/4 inch length of cut, and a 3 inch overall length. The 5-flute, right-hand geometry is finished with a nACo (WJ30EM) coating that extends tool life under high-heat cutting conditions. It is a single-end, centercutting design suited for milling, slotting, and contouring operations. Licensed machinists and tool-and-die professionals are the primary installers and operators of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use in CNC machining centers and manual milling machines where high-performance cutting in difficult-to-machine materials is required. Its extended reach configuration, with a 1.5039 inch reach length, makes it well suited for deep-pocket milling and profiling operations in aerospace, medical, and energy-sector component work. The MA377.A-5-R series positions it as a roughing and finishing capable tool, reducing the need for multiple tool changes in a single operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and thermal resistance in superalloy and titanium cutting\u003c\/li\u003e\n  \u003cli\u003enACo coating (WJ30EM proprietary designation) provides oxidation resistance at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e5-flute geometry balances chip evacuation with surface finish quality\u003c\/li\u003e\n  \u003cli\u003e0.0150 inch corner radius reduces stress concentration at the cutting edge and extends tool life\u003c\/li\u003e\n  \u003cli\u003e38 degree helix angle promotes smooth cutting action and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 1.5039 inch reach length supports deep-pocket and hard-to-access feature machining\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with CNC machining centers and milling machines accepting a 1\/2 inch straight-cylindrical shank with h6 tolerance.

Secure the shank fully in a collet or end mill holder rated for the shank diameter before running the spindle. Verify spindle speed, feed rate, and depth of cut against the material being machined before beginning a cut. Do not exceed the tool's rated cutting envelope, and inspect the corner radius edge for chipping before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0150 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.5039 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: nACo (WJ30EM)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel and Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MA377.A-5-R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturers Catalog Number\u003c\/strong\u003e: MA377.12.7A5S038-WJ30EM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 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: WALTER-PROTOTYP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8417679\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67906451308850,"sku":"8417679","price":208.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6019f2a66324a263c8eb9cf3cf62e235.jpg?v=1791168310","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-8417679-corner-radius-end-mill-1-2-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
