Built to the MC326 series specification, it features a 1\/2 inch cutting diameter, a 0.12 inch corner radius, and a TiAlN (PVD) coating that extends tool life at elevated cutting temperatures. The 4-flute, right-hand spiral geometry supports both roughing and finishing operations in a single tool. With a long-length configuration and extended reach, this end mill suits deep-pocket and complex-profile work where standard-length tooling falls short. It is a single-end, centercutting design, allowing direct plunge entry where required.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers with standard toolholders accepting a 1\/2 inch straight-cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, and superalloys and titanium. Secondary materials include hard materials and additional grades of cast iron and stainless steel. The extended reach and long length of cut make it well suited to deep-wall milling, rib machining, and contour finishing in aerospace, die and mold, and general precision metalworking applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.12 inch corner radius reduces stress concentration and improves surface finish at part edges\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating provides oxidation resistance and thermal hardness for dry and semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral geometry supports both roughing and finishing operations\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eExtended reach with 2.967 inch reach length suits deep-pocket and long-cavity work\u003c\/li\u003e\n\u003cli\u003eHigh helix style promotes chip evacuation in gummy and work-hardening materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard toolholders accepting a 1\/2 inch straight-cylindrical shank.

The machine spindle must be stopped and the tool path verified before mounting. Secure the shank fully within the toolholder to the manufacturer-specified engagement depth and confirm runout with a dial indicator before the first cut. Do not exceed the toolholder's rated speed and torque capacity for this shank diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.12 inches\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: 1 inch (declared); 3.0 inches (decimal attribute)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.475 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.967 inches\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: TiAlN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\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\u003eSeries\u003c\/strong\u003e: MC326\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.445 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: WALTER-PROTOTYP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6579293\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67914118496562,"sku":"6579293","price":546.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fefb874364c251f58fa4689b3954e4cb_e00dca72-5672-43c8-bc88-c4f7d5ffb209.jpg?v=1791247381","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-6579293-corner-radius-end-mill-1-2in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
