It features a 1\/8 inch cutting diameter, a 3\/8 inch length of cut, and four flutes with a 30-degree helix angle. The AlTiN coating extends tool life when cutting hardened steels, stainless steels, and high-temperature alloys. At 2 inches overall length with a 1 inch reach, this end mill is built for extended-reach applications where standard-length tooling cannot access the workpart geometry. Centercutting capability allows for plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual knee mills running ferrous and non-ferrous materials. The right-hand cut and right-hand flute direction are standard for conventional spindle rotation. The 1\/8 inch shank diameter fits common ER and other collet systems in that bore size. Typical applications include slot milling, profile milling, and finishing passes in tight-clearance features such as keyways, pockets, and contoured surfaces. The extended-reach geometry supports work in deep pockets and stepped features where a shorter tool would bottom out before reaching full depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating for improved heat resistance and tool life in hardened and abrasive materials\u003c\/li\u003e\n\u003cli\u003eFour flutes with 30-degree right-hand helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eExtended reach at 1 inch for deep-pocket and step-down applications\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 1\/8 inch shank for standard collet compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for CNC machining centers and manual mills accepting a 1\/8 inch shank diameter collet or chuck system.\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 powered-down state before changing tooling. Seat the shank fully into the collet to the minimum engagement depth recommended by the collet manufacturer to prevent pullout under cutting loads. Verify runout with a dial indicator after clamping, as excessive runout accelerates flute wear and degrades surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\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: 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\u003eExtended Reach\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\u003eConfiguration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 972308-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51732065026354,"sku":"972308-C3","price":77.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e92c096bc6ef0f75423e38273f3a3bd_db41dfed-2ae4-42c9-85a1-f15f9a811ac7.jpg?v=1788738811","url":"https:\/\/voomisupply.com\/products\/harvey-tool-972308-c3-square-end-mill-1-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
