With a 1\/8 inch mill diameter and a 3\/4 inch length of cut, this long-flute tool is built for deep-reach profiling and contouring in tight geometries. The AlTiN PVD coating provides thermal resistance and wear protection, making it suitable for high-speed machining without coolant. Three right-hand helical flutes with a variable 20-degree helix angle promote chip evacuation and reduce chatter in challenging workpiece materials. Machinists and CNC operators working in die-mold, aerospace, and precision component shops are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing operations in hard materials where a long-flute reach is required. The 3\/4 inch reach length and 2.5 inch overall length allow access to deep pockets, slots, and contoured surfaces that shorter tools cannot reach. Its single-end configuration and straight cylindrical 1\/8 inch shank fit standard collet systems commonly used in vertical machining centers and CNC routers. Primary workpiece materials include hard material grades as well as steel, stainless steel, and cast iron.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8 inch ball nose diameter with 0.0625 inch nose radius for precise contouring\u003c\/li\u003e\n\u003cli\u003e3\/4 inch length of cut in a long-flute configuration for deep-reach applications\u003c\/li\u003e\n\u003cli\u003e3 right-hand helical flutes with variable 20-degree helix angle to reduce chatter and improve chip flow\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for heat and wear resistance in hard and ferrous materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eSingle-end design with straight cylindrical 1\/8 inch shank compatible with standard collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting a 1\/8 inch straight cylindrical shank.

Seat the shank fully in the collet and torque the collet nut per the collet manufacturer specification before running. Verify runout with a dial indicator after mounting, as excessive runout on miniature tooling accelerates wear and can cause premature breakage. Do not exceed the tool manufacturer recommended depth of cut or feed rate for the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 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: 20 degrees (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: 0.75 inches\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: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature End Mills - Ball - Long Flute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 877208-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51736518951218,"sku":"877208-C3","price":70.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94ad60eae1794608cee238b1a4adad97_89b45739-862a-4564-b0d3-987f1adaa63c.jpg?v=1788778395","url":"https:\/\/voomisupply.com\/products\/harvey-tool-877208-c3-ball-end-mill-1-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
