Machined from solid carbide, it features a 1\/8-inch cutting diameter, a 3\/8-inch length of cut, and a 42-degree variable helix angle. The variable helix geometry reduces harmonic vibration during high-speed roughing passes, improving surface finish and tool life. TiB2 (titanium diboride) PVD coating provides low affinity to aluminum, reducing built-up edge and extending tool life in non-ferrous applications. This end mill is used by CNC machinists and tool-and-die professionals running aluminum parts on vertical or horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing operations in aluminum alloys, copper, brass, and other non-ferrous materials. The 1\/8-inch shank diameter with a straight-cylindrical profile fits standard collet chucks and ER-style toolholders. The 3-flute configuration balances chip evacuation with rigidity, making it effective for slotting, profiling, and contour milling in small-feature aluminum components. The 3\/8-inch reach length supports access to moderately deep pockets without excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e42-degree variable helix angle reduces chatter and harmonic vibration during roughing\u003c\/li\u003e\n  \u003cli\u003eTiB2 PVD coating minimizes aluminum adhesion and built-up edge\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral geometry balances chip evacuation with cutting stability\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with straight-cylindrical shank for standard collet compatibility\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for conventional CNC spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the HARVEY TOOL Variable Helix End Mills for Aluminum Alloys - Ball series within the Material Specific End Mills line.

Ensure the toolholder is clean and within runout tolerance before seating the shank, as excessive runout will accelerate wear on a small-diameter carbide tool. Confirm spindle speed and feed rate are appropriate for the 1\/8-inch diameter before engaging the cut. Do not use this tool on ferrous materials, as it is 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: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eNose Radius\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\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: TiB2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: 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\u003eSingle or Double End\u003c\/strong\u003e: Single\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 Material\u003c\/strong\u003e: Non-Ferrous Metal\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 989808-C8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728734159154,"sku":"989808-C8","price":74.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc4adc9963dc369d8d0bae80439b1132.jpg?v=1788695600","url":"https:\/\/voomisupply.com\/products\/harvey-tool-989808-c8-ball-end-mill-1-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
