With a 2.5 mm (0.0980 inch) cutting diameter and a 4-flute geometry, it delivers efficient material removal and a fine surface finish in a single-end configuration. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. An AlTiN (aluminum titanium nitride) coating provides elevated heat resistance and extended tool life in hard and abrasive materials. This end mill is right-hand cutting with right-hand flute direction and is center-cutting capable, allowing plunge entry. It is sized for use in precision CNC machining centers and manual mills by machinists and tooling professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling ferrous and non-ferrous metals, hardened steels, and high-temperature alloys where a small-diameter, coated carbide tool is required. The 0.125 inch shank diameter fits standard collets and tool holders commonly used in CNC machining centers, die and mold work, and precision prototype machining. The compact 1.5 inch overall length and 0.294 inch length of cut make it well matched for shallow-to-medium depth slotting, profiling, and contouring operations in tight workpiece geometries.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for high-heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e4-flute design balances chip clearance and surface finish quality\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard small-diameter square end mill for use in CNC machining centers and manual mills accepting a 0.125 inch shank via collet or end mill holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists using appropriate collet chucks or end mill holders rated for the 0.125 inch shank diameter. Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Verify runout with a dial indicator after seating to minimize premature wear. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for the specific workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 2.5 mm (0.0980 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.294 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\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\u003eCentercutting\u003c\/strong\u003e: Yes\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: 73098-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51737158156594,"sku":"73098-C3","price":49.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b439e4d9750d2d519b94c7aaf8826d59_8773d420-c381-4bc3-8134-8ce7a8dec855.jpg?v=1788785048","url":"https:\/\/voomisupply.com\/products\/harvey-tool-73098-c3-square-end-mill-2-5mm-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
