It features a 1\/2 inch cutting diameter, a 1-1\/2 inch length of cut, and a 42-degree variable helix angle that reduces chatter and improves chip evacuation during aggressive material removal. With three flutes and a spiral flute geometry, it is suited for roughing operations where chip load and cutting efficiency are priorities. Machinists and tool-and-die professionals use this end mill in CNC machining centers where surface finish and dimensional accuracy are critical.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for material-specific applications, particularly aluminum alloys and non-ferrous metals, though its carbide substrate also handles steel, stainless steel, and cast iron. It is part of the HARVEY TOOL Variable Helix End Mills for Aluminum Alloys - Ball series. The single-end, straight-cylindrical 1\/2 inch shank makes it compatible with standard ER and end mill holders. It is used in both roughing passes and contour work where the ball nose profile is required for 3D surface work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix angle at 42 degrees reduces harmonics and chatter during deep cuts\u003c\/li\u003e\n\u003cli\u003e3-flute spiral geometry optimized for efficient chip evacuation in aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBall nose profile with 0.25 inch nose radius enables 3D contouring and profiling operations\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance across a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with or without coolant in standard machining environments\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction; single-end design with no extended reach\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers with standard straight-cylindrical shank tool holders.

Ensure the machine spindle is fully stopped and locked out before inserting or changing tooling. Use a calibrated torque wrench and the appropriate collet or end mill holder to secure the 1\/2 inch shank to the specified clamping torque for the holder in use. Verify runout with a dial indicator after tool installation to maintain dimensional accuracy and tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.2500 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: 42 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal\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\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.31 inches L x 0.51 inches W x 0.51 inches H\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 989832\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51747220291890,"sku":"989832","price":97.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32610f7e9a490f683156897a0d497f3e_46573220-0e0b-4a99-aeeb-93744a741aa2.jpg?v=1788877617","url":"https:\/\/voomisupply.com\/products\/harvey-tool-989832-ball-end-mill-1-2-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
