Built from micrograin carbide with a TiCN (Titanium Carbonitride) coating, it delivers extended tool life and improved wear resistance in ferrous and non-ferrous applications. The 3\/8 inch cutting diameter and 1-1\/2 inch length of cut pair with a 40-degree helix angle and spiral flute geometry to promote efficient chip evacuation and smooth cutting action. At 6 inches overall length, this is an extra-long configuration suited for deep-reach milling where standard-length tools cannot access the workpiece. Machinists, tool-and-die makers, and CNC operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is well suited for slotting, profiling, and peripheral milling in steel, stainless, cast iron, and similar materials where a TiCN finish provides adequate lubricity and heat resistance. The extra-long 6 inch OAL makes it appropriate for cavity work, deep pockets, and fixture-limited setups in job shop and production environments. Its centercutting design allows plunge entry directly into the workpiece without a pre-drilled pilot hole, adding flexibility to its application range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and reduces built-up edge in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting capable — allows direct plunge milling without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eExtra-long 6 inch OAL with 1-1\/2 inch length of cut for deep-reach applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute spiral geometry; single-end configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8 inch shank square end mill compatible with milling machine spindles, CNC machining centers, and manual knee mills accepting ER collets, end mill holders, or similar 3\/8 inch straight-shank toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the holder to the depth mark or manufacturer minimum engagement spec for the collet or holder in use; insufficient engagement can cause tool pullout under load. Verify runout with a dial indicator after clamping and before initiating a cut, particularly given the extra-long reach of this tool which amplifies deflection at the tip.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12182308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737368985906,"sku":"12182308","price":109.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11a86f216cb3e1a95b35c77f4610ebfa.jpg?v=1788787688","url":"https:\/\/voomisupply.com\/products\/accupro-12182308-square-end-mill-3-8-in-3-flute-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
