The 3\/4-inch diameter cutter features a 1\/8-inch (0.1250-inch) corner radius and four flutes with a high-helix spiral geometry, promoting efficient chip evacuation and smooth surface finishes. A physical vapor deposition (PVD) TiAlN coating adds thermal and wear resistance at the cutting edge, extending tool life in high-temperature machining environments. This is a single-end, centercutting tool suited for slotting, profiling, and ramping cuts across both roughing and finishing operations.\u003c\/p\u003e\u003cp\u003eThis end mill is built for CNC machining centers and manual mills where rigidity and tool life matter. It targets steel, stainless steel, cast iron, superalloys, and titanium workpieces, covering ISO material codes P, M, K, and S. The 3\/4-inch straight-cylindrical shank mounts directly into standard toolholders. With an extended reach and 1-1\/2-inch length of cut, it handles moderate-depth pockets and contoured features without requiring a specialty holder. Machinists and toolroom professionals working in job shops, production floors, and maintenance environments will find this tool appropriate for a wide range of part geometries in hard and abrasion-resistant materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-inch diameter with 1\/8-inch corner radius for edge-blending and radius-floor pockets\u003c\/li\u003e\n\u003cli\u003eFour-flute, high-helix spiral geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating for elevated heat and wear resistance in ferrous and superalloy cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables plunge entry without a pre-drilled start hole\u003c\/li\u003e\n\u003cli\u003eExtended reach with 1.969-inch reach length accommodates moderate-depth features\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting and right-hand flute direction; fits standard right-hand toolholders\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance h9 and shank diameter tolerance h5 for consistent runout in precision setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-bore toolholders accepting a 3\/4-inch cylindrical shank.

Secure the shank fully within the toolholder to the manufacturer-recommended gauge-line depth before tightening. Confirm runout with a dial indicator before starting a cut, especially in high-speed or tight-tolerance operations. Coolant-through is not supported on this tool; use flood or mist coolant externally where applicable, following your machine tool and shop safety procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 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: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.969 inches\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\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: TiAlN (PVD)\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, 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: MC326\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.776 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: 6579280\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67951292743986,"sku":"6579280","price":785.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8368f85200014744fee497104f580cc3_131a5d67-c481-400b-8051-e6a91694e326.jpg?v=1791724126","url":"https:\/\/voomisupply.com\/products\/walter-prototyp-6579280-corner-radius-end-mill-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
