With a 0.125 inch cutting diameter, 0.375 inch length of cut, and a 4-flute geometry with a 30-degree helix angle, this tool delivers smooth chip evacuation and stable cutting performance in ferrous and non-ferrous materials. The AlTiN coating provides elevated heat resistance and extended tool life at higher cutting speeds. Right-hand cut and right-hand flute orientation are standard. This end mill is selected and installed by machinists and CNC programmers running production or prototype milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, profiling, and finishing passes in tight-tolerance applications. The 0.125 inch shank diameter matches the cutting diameter, and the 0.625 inch reach length and 1.5 inch overall length make it appropriate for shallow-to-moderate depth features. Extended reach geometry allows access to recessed walls or pocketed areas without sacrificing rigidity at this diameter. Compatible with standard 1\/8 inch collet systems on CNC vertical machining centers and high-speed spindles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-temperature performance and extended tool life\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e4-flute design balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable  -  suitable for plunge entry\u003c\/li\u003e\n\u003cli\u003eExtended reach geometry for access to recessed features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/8 inch collet chucks and ER-style collet systems on CNC machining centers.

Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before tool changes. Use a properly sized collet and torque the collet nut according to the toolholder manufacturer specifications. Confirm tool runout with a dial indicator after clamping, particularly at this diameter, as runout sensitivity is high in small-diameter end mills.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: AlTiN\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 956908-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51739797717298,"sku":"956908-C3","price":77.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a126ac4ecbfdfa61160608f49f809f8_59e33b04-8b7e-4f3b-8eaa-53e91a97a65d.jpg?v=1788818968","url":"https:\/\/voomisupply.com\/products\/harvey-tool-956908-c3-square-end-mill-0-125in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
