It features a 1\/8 inch (0.1250 inch) cutting diameter, a 3\/16 inch (0.187 inch) length of cut, and four flutes ground with a 30-degree right-hand helix. The AlTiN coating improves heat resistance and extends tool life in ferrous and hard materials. With a 2-1\/2 inch overall length and a reduced 3 mm (0.1181 inch) shank diameter, this end mill is suited for CNC machining centers where a reduced-shank configuration is required. It is centercutting, allowing plunge entry into the workpiece.\u003c\/p\u003e\u003cp\u003eThis end mill is used in precision CNC milling operations on ferrous metals, stainless steels, titanium, and hardened alloys where heat generation and tool wear are primary concerns. The reduced shank allows it to fit standard collet toolholders while reaching into tighter workspaces. Machinists and tooling technicians working in aerospace, medical device, and precision job-shop environments will find this geometry suitable for slotting, profiling, and pocketing operations within its length-of-cut range of 0.100 to 0.200 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8 inch cutting diameter with four-flute geometry for improved chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high heat resistance and extended tool life in hard and ferrous materials\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix angle balances cutting forces and reduces chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eReduced shank at 3 mm diameter enables use in tighter setups and extended-reach toolholders\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction maintains rigidity and edge integrity at high spindle speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill compatible with standard CNC collet toolholders accepting a 3 mm shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist or CNC tooling technician with the spindle fully stopped and machine in a safe, locked-out state. Seat the shank fully and evenly in the collet before torquing to the toolholder manufacturer's specification. Inspect the cutting edges and coating condition before mounting; carbide end mills are brittle and can chip if dropped or improperly handled. Follow the machine tool manufacturer's recommended runout tolerance for small-diameter tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.187 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.100 to 0.200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (2-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Reduced\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 943208-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728450584882,"sku":"943208-C3","price":168.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8a5e745aa5ba7fe5bb98ac386c683d4.jpg?v=1788691373","url":"https:\/\/voomisupply.com\/products\/harvey-tool-943208-c3-square-end-mill-1-8-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
