It measures 0.125 inches in diameter with a 0.25-inch length of cut and a 1.5-inch overall length. The three-flute design with a 45-degree helix angle balances chip evacuation and surface finish, while the TiAlN coating extends tool life in demanding cutting conditions. Material grade IC900 makes this end mill suitable for use in ferrous alloys, cast irons, stainless steels, superalloys, and similar materials. It is centercutting and features a right-hand cut with right-hand spiral flutes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where small-diameter, high-precision cutting is required. The straight cylindrical shank at 0.125 inches fits standard 1\/8-inch collet chucks. It is well suited for slotting, peripheral milling, and profiling in ferrous and difficult-to-machine materials coded H, K, M, P, and S under standard workpiece material classifications. The regular length designation makes it appropriate for general-purpose milling where extended reach is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with IC900 material grade for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for elevated-temperature performance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eThree-flute configuration balances material removal rate and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute geometry for standard CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with workpiece materials coded H, K, M, P, and S, covering hardened steels, cast irons, stainless steels, titanium, and other superalloys.

Ensure the machine spindle is fully stopped and the controller is in a safe state before loading or removing the tool. Seat the shank fully in the collet and torque the collet nut to the specification published by the collet manufacturer. Verify runout with a dial indicator before beginning a cutting operation, particularly at this diameter where tool deflection is a concern.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches (1-1\/2 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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: IC900\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5621041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51755251368242,"sku":"5621041","price":65.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b3282fb0719343c9fdcdeef6efad1b8_7ebf7667-d9f7-4525-83ba-6688b8698bef.jpg?v=1788952671","url":"https:\/\/voomisupply.com\/products\/iscar-5621041-square-end-mill-0-125in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
