Built from micrograin solid carbide, it delivers the rigidity and edge retention required for ferrous and non-ferrous cutting. The 0.375-inch diameter cutting face is finished with TiCN (Titanium Carbonitride) coating, which increases surface hardness and reduces friction at the cutting edge. With a 40-degree helix angle and spiral flute geometry, this end mill promotes efficient chip evacuation and smooth cutting action. It is centercutting, allowing direct plunge entry into a workpiece. This tool is sold as a single unit and is intended for use by machinists and tool-and-die professionals on CNC mills and manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for production and job-shop milling environments where a long-reach, two-flute tool is required. The 1.125-inch length of cut and 3.0-inch overall length make it appropriate for slotting, profiling, and peripheral milling at moderate depths. The right-hand cut, right-hand flute configuration is the standard orientation for conventional and climb milling on most vertical machining centers. It performs well in aluminum, steel, stainless, and hardened alloys where a TiCN-coated carbide substrate is recommended.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction provides high rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces built-up edge on ferrous materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral geometry suited for slotting and full-width cuts\u003c\/li\u003e\n  \u003cli\u003eLong-reach configuration with 1.125-inch LOC and 3.0-inch OAL for deeper cavity work\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 ER collet chucks, end mill holders, and Weldon-style tool holders accepting a 0.375-inch shank diameter on CNC machining centers and manual mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the tool holder and torque the retention mechanism per the holder manufacturer specifications. Verify runout with a dial indicator before engaging the cut, as carbide end mills are sensitive to excessive runout which can cause chipping or premature failure.\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: 2\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\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1-1\/8 inch (1.1250 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 (OAL)\u003c\/strong\u003e: 3 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\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: 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\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\u003eExtended Reach\u003c\/strong\u003e: No\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: 12181726\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749471158578,"sku":"12181726","price":75.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b1ce43efb1895ee26d37080d828b0e7.jpg?v=1788906479","url":"https:\/\/voomisupply.com\/products\/accupro-12181726-square-end-mill-3-8-in-2-flute-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
