With a 3\/4-inch cutting diameter, a 2.25-inch length of cut, and a 40-degree high helix angle, this tool is built for both roughing and finishing passes in a single setup. The Zplus PVD coating reduces heat buildup and extends tool life in non-ferrous applications. The variable pitch flute geometry helps suppress chatter and maintain surface finish quality at aggressive feed rates. The straight cylindrical shank and h6 tolerance on both shank and mill diameter ensure consistent runout in standard end mill holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers running aluminum structural components, aerospace profiles, mold work in non-ferrous stock, and general production applications where tool life and finish quality matter. The single-end, right-hand cutting configuration fits conventional climb-milling strategies common in aluminum work. At 5 inches overall length with a 2.25-inch reach, it handles moderate-depth pockets and slots without excessive overhang. The 0.375-inch nose radius produces a full ball profile for contour milling, 3D surfacing, and ramping operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch ball end mill with 0.375-inch nose radius for contour and 3D surface milling\u003c\/li\u003e\n  \u003cli\u003e40-degree high helix angle optimized for chip evacuation in aluminum and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eZplus PVD coating for extended tool life and reduced built-up edge in non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVariable pitch flute spacing reduces harmonic chatter at high feed rates\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction with h6 shank and diameter tolerances for low runout\u003c\/li\u003e\n  \u003cli\u003eRated for both roughing and finishing operations in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in aluminum alloys and non-ferrous metals.

Secure the 3\/4-inch straight shank in a properly sized end mill holder or collet chuck and verify runout against the stated TIR maximum of 0.0003 inches before cutting. Power down and lock out the spindle before tooling changes. Do not use this tool on ferrous materials, as the coating and geometry are optimized specifically for non-ferrous applications.\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 (0.75 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 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\u003eNose Radius\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\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: Zplus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620 \/ -0.0620 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0003 inches\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 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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.895 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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51736992514354,"sku":"49421","price":521.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0386461b81181a3167350060a0d7b8dc_8b1635f5-3f60-4811-8231-087ab00eb47a.jpg?v=1788782835","url":"https:\/\/voomisupply.com\/products\/helical-solutions-49421-ball-end-mill-3-4in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
