Built from solid carbide and coated with AlTiN (aluminum titanium nitride), it handles high-temperature cutting conditions common in ferrous and hard-alloy materials. The mill measures 0.125 inches in diameter with a 0.25-inch length of cut and a 1.5-inch overall length. Its stub-length profile provides rigidity in tight setups where overhang must be minimized. Right-hand cutting and right-hand helical flutes are standard on this series.\u003c\/p\u003e\n\u003cp\u003eThe 200-4125 is suited for milling slots, pockets, and profiles in CNC machining centers and manual mills where a small-diameter, high-performance tool is required. The double-end design extends tool life by providing a second usable cutting end. The Series 200 stub configuration is a common choice for jobs requiring maximum stiffness at small diameters, particularly in production environments machining steel, stainless, or hardened alloys. It is used by machinists, tool-and-die technicians, and CNC operators across job shop and production settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for hardness and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides heat resistance and extended tool life at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003eDouble-end design offers two cutting ends per tool, reducing per-edge cost\u003c\/li\u003e\n  \u003cli\u003eFour helical flutes with right-hand cutting direction for smooth chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStub-length profile maximizes rigidity and minimizes deflection at 0.125-inch diameter\u003c\/li\u003e\n  \u003cli\u003eSquare shank, 0.125-inch diameter for standard collet and end mill holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting 1\/8-inch shank end mills with standard collet or end mill holder tooling systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended gauge length before torquing the retention nut. Do not use this tool for plunge cutting, as this end mill is non-centercutting.\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\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 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\u003eShank Type\u003c\/strong\u003e: Square\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\/Finish\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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: HTC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 200-4125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HTC","offers":[{"title":"Default Title","offer_id":68383443845426,"sku":"200-4125","price":28.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35f784719ad14dbea38b708619071a96.jpg?v=1793901260","url":"https:\/\/voomisupply.com\/products\/htc-200-4125-square-end-mill-1-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
