It features a 1-inch cutting diameter with a 1.5-inch length of cut, four right-hand spiral flutes, and a 38-degree helix angle. The tool is coated with TiAlCN for improved heat resistance and wear life at elevated cutting speeds. The carbide substrate is submicron grade, which supports both toughness and edge retention. Variable index spacing on the flutes helps reduce chatter and vibration during aggressive cuts. This end mill is intended for use by machinists and CNC tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill suits ferrous and hardened material applications where surface finish and dimensional accuracy are critical. The centercutting geometry allows for plunge entry as well as conventional peripheral milling. It is well suited for roughing and semi-finishing passes on steel, stainless steel, and high-temperature alloys. The single-end, right-hand cutting configuration is standard for CNC vertical machining centers and manual knee mills with a 1-inch collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch mill diameter with 1.5-inch length of cut for deep slot and pocket work\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes with variable index to suppress harmonic chatter\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eTiAlCN coating provides thermal protection and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade balances edge sharpness with fracture resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or first-install solid carbide square end mill for CNC machining centers and manual mills accepting a 1-inch straight shank in a standard end mill holder or collet chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before loading or changing tooling. Seat the shank fully in the holder to the recommended minimum engagement depth per the holder manufacturer and torque set screws to the holder specification. Inspect the tool edge and coating for chips or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\/Finish\u003c\/strong\u003e: TiAlCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.49 inches L x 1.34 inches W x 1.34 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.04 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: 3398353\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51733305164082,"sku":"3398353","price":566.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ba32a6c345bc1a81625bb9fb60cc37b_31861d79-637b-41f0-a314-327edf81a497.jpg?v=1788753911","url":"https:\/\/voomisupply.com\/products\/iscar-3398353-square-end-mill-1-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
