It features a 3\/8-inch mill diameter, a 1-1\/2-inch length of cut, and a 40-degree high helix angle with variable pitch geometry. The Zplus PVD coating provides lubricity and edge hardness suited to non-ferrous applications. At 3-1\/2 inches overall length with a 3\/8-inch straight-cylindrical shank, this tool fits standard collet and end mill holders used by CNC machinists in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for both roughing and finishing passes in aluminum alloys and non-ferrous metals. The variable pitch flute spacing reduces harmonic chatter during aggressive material removal, making it effective on CNC machining centers, knee mills, and high-speed spindle setups. The ball nose profile allows profiling, contouring, and 3D surface work where a flat-bottom tool cannot reach. It is intended for use in professional machine shop environments where tooling performance directly affects cycle time and surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-flute variable pitch design reduces chatter in non-ferrous and aluminum alloy cuts\u003c\/li\u003e\n  \u003cli\u003e40-degree high helix angle promotes efficient chip evacuation from the cutting zone\u003c\/li\u003e\n  \u003cli\u003eZplus PVD coating enhances edge lubricity and wear resistance on non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBall nose geometry supports profiling, contouring, and 3D surface finishing\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability under load\u003c\/li\u003e\n  \u003cli\u003eCapable of both roughing and finishing material removal 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; part of the HELICAL SOLUTIONS 3 Flute Ball 40 Helix Variable Pitch End Mills for Aluminum Alloys and Non-Ferrous Materials series.

Verify runout does not exceed the maximum TIR specification before beginning a cut. Follow machine manufacturer guidelines for tool clamping torque and stick-out length to maintain rigidity. Inspect the cutting edges for wear or chipping before each setup and replace the tool at the first sign of edge degradation to avoid workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches (3.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.1875 inches\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\u003eVariable Pitch\u003c\/strong\u003e: Yes\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 (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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\u003eMaximum TIR\u003c\/strong\u003e: 0.0003 inches\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: 0.161 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: 49241\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51732373766450,"sku":"49241","price":152.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0386461b81181a3167350060a0d7b8dc_0cace94d-42a4-4269-8181-2006d6493a85.jpg?v=1788742197","url":"https:\/\/voomisupply.com\/products\/helical-solutions-49241-ball-end-mill-3-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
