It carries a 3\/8 inch cutter diameter with a 1-1\/2 inch length of cut and a 4 inch overall length. The micrograin carbide substrate is finished with an AlTiN (aluminum titanium nitride) coating, which supports elevated cutting temperatures and extends tool life in ferrous and hardened materials. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Centercutting geometry allows plunge milling as well as conventional peripheral cuts. Machinists and tool-and-die professionals select this end mill for finishing and semi-finishing operations where tight tolerances and surface finish matter.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits CNC machining centers and manual knee mills running steel, stainless, cast iron, and similar hard materials. The spiral flute design and right-hand cut with right-hand flute configuration follow standard conventions for most vertical milling setups. It is well suited to applications requiring longer reach into pockets or slots where a shorter tool would not clear the workpiece. The single-end configuration is standard for precision work requiring consistent runout control.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-flute geometry increases feed rate capability and improves surface finish compared to 4-flute designs\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating extends tool life in high-heat cutting environments and reduces built-up edge on ferrous materials\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes aggressive chip evacuation and lowers radial cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate provides rigidity and wear resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard 3\/8 inch collet or end mill holder setups on CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Secure the shank in a properly sized collet, end mill holder, or shrink-fit holder rated for the 3\/8 inch shank diameter, and verify runout before starting a cut. Power down and lock out the spindle before changing or adjusting any tooling. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eOverall Length\u003c\/strong\u003e: 4 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\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\u003eWeight\u003c\/strong\u003e: 0.231 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.13 x 0.63 x 0.63 inches\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: 12177416\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729480515890,"sku":"12177416","price":97.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/762fe1eb731bf32dbbf94f266405111e.jpg?v=1788705103","url":"https:\/\/voomisupply.com\/products\/accupro-12177416-square-end-mill-3-8-in-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
