It features a 0.5 inch diameter with four flutes, a 1.25 inch length of cut, and a 38-degree helix angle. The cutting edges are coated with TiAlCN for improved wear resistance and heat tolerance at elevated cutting speeds. With a 3 inch overall length and a 0.5 inch shank diameter, this end mill fits standard collet chucks and milling tool holders used in CNC and manual vertical milling setups. It is centercutting, allowing plunge entry directly into workpiece material.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and pocket milling in ferrous and non-ferrous materials. The right-hand cutting and right-hand flute direction make it compatible with conventional CNC machining center spindle rotation. The variable index geometry combined with a spiral flute type helps reduce chatter during aggressive side milling passes. It is typically installed and used by machinists, CNC operators, and tool and die professionals working in job shops, aerospace component machining, and general precision manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlCN coating provides thermal and wear resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle supports efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration during heavy cuts\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade substrate delivers edge integrity at high feed rates\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 0.5 inch collet chucks, shrink-fit holders, and side-lock milling tool holders on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the tool holder to the minimum insertion depth recommended by the holder manufacturer before tightening. Confirm runout with a dial indicator after installation and before beginning a cut cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 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\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlCN\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\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: 0.38 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3398309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727209857330,"sku":"3398309","price":103.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ba32a6c345bc1a81625bb9fb60cc37b_fe456243-e1bf-4e6c-9846-84ac6a94cfb9.jpg?v=1788674754","url":"https:\/\/voomisupply.com\/products\/iscar-3398309-square-end-mill-0-5in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
