It features a 5 mm (0.197 inch) cutting diameter, a 0.50 mm (0.02 inch) corner radius, and 3 flutes with a high-helix, right-hand spiral geometry. The cutting edge is coated with TiAlN via PVD process, providing thermal resistance and extended tool life in steel, stainless steel, cast iron, and superalloy and titanium workpieces. Designed as a single-end, centercutting tool, it handles both roughing and finishing operations without a tool change. This is a long-reach configuration intended for use with standard straight-cylindrical toolholders.\u003c\/p\u003e\n\u003cp\u003eThe 6579469 is suited for CNC milling operations on machining centers in job shop, production, and precision manufacturing environments. Its extended reach, with a 21 mm (0.63 inch) reach length and 4.80 mm neck diameter, allows access to deeper pockets and stepped features without interference. Primary workpiece materials include steel, stainless steel, cast iron, and superalloys and titanium. Secondary applications cover hard materials and additional cast iron and stainless steel conditions. The coarse pitch and high-helix geometry support efficient chip evacuation during aggressive cuts. This tool is part of the Walter MC326 series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with TiAlN PVD coating for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003e0.50 mm corner radius reduces stress concentration and extends edge life at workpiece corners\u003c\/li\u003e\n  \u003cli\u003e3-flute, high-helix right-hand spiral geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 21 mm reach length and 4.80 mm neck diameter for deep pocket access\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eh9 mill diameter tolerance and h5 shank tolerance ensure precise fitment in toolholders\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through; suitable for dry or external coolant delivery setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with straight-cylindrical toolholders.

Primary workpiece materials are steel, stainless steel, cast iron, and superalloys and titanium (material codes P, M, K, S).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle and toolholder are fully de-energized and at rest before inserting or removing the tool. Verify the shank is seated to the correct gauge length in the toolholder and that clamping torque matches toolholder manufacturer specifications. Do not exceed the rated cutting parameters for the workpiece material category; consult the Walter MC326 series cutting data tables for feed and speed guidance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5.00 mm (0.197 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.50 mm (0.02 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 13.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 57.00 mm (2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 4.80 mm (0.187 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 21.00 mm (0.63 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix\u003c\/strong\u003e: High (50 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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eCoating\u003c\/strong\u003e: TiAlN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MC326\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.055 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: 6579469\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67906783805746,"sku":"6579469","price":168.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e7bd2ac82ade1ceeb70361cd58e9cce.jpg?v=1791171451","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-6579469-corner-radius-end-mill-5mm-3fl-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
