It features a 3\/4 inch cutting diameter, a 1-5\/8 inch length of cut, and a 0.03 inch corner radius that reduces stress concentrations at the tool tip and extends tool life. With 3 right-hand helical flutes and a coarse pitch, this single-end, centercutting mill is suited for roughing passes where chip evacuation and edge strength are priorities. The uncoated submicron carbide construction delivers consistent performance in aluminum, brass, copper, and similar non-ferrous workpiece materials. It is installed using standard end mill holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual milling machines where non-ferrous metal stock is being profiled, slotted, or ramped. The centercutting geometry allows plunge entry, giving machinists flexibility in programming tool paths. The straight-cylindrical shank with h6 tolerance fits precisely into end mill holders, collet chucks, and hydraulic tool holders sized for 3\/4 inch shanks. It is best applied in roughing operations where a small corner radius is specified to blend floor and wall transitions without sharp corners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for rigidity and wear resistance in non-ferrous cutting\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius reduces corner chipping and blends floor-to-wall transitions\u003c\/li\u003e\n  \u003cli\u003e3 right-hand helical flutes with coarse pitch for efficient chip evacuation during roughing\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h6 tolerance for precise tool holder fitment\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish suitable for non-ferrous materials where coating adhesion is not required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders accepting a 3\/4 inch straight-cylindrical shank.

Power down and lock out the spindle before seating or removing the end mill from the holder. Verify holder bore diameter and shank diameter match before applying clamping torque per the holder manufacturer specifications. Inspect the tool shank and holder bore for chips or contamination before assembly to maintain runout within acceptable limits.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches \/ 19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (41.27 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (101.60 mm)\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\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\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1020\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 120690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51972983685426,"sku":"120690","price":352.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd1a77350ecefbd2b2d03c7168ca3a50_c1bed3f1-13df-4875-b10b-fe1576ff541b.jpg?v=1789971481","url":"https:\/\/voomisupply.com\/products\/gws-120690-corner-radius-end-mill-3-4-in-3-flutes-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
