It features a 0.375-inch mill diameter, a 0.75-inch length of cut, and a 3.5-inch overall length, making it suited for standard-depth slotting, profiling, and peripheral milling tasks. Constructed from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it handles elevated cutting temperatures and resists wear in ferrous and hardened materials. The 2-flute configuration and 40-degree helix angle promote efficient chip evacuation. This tool is installed and operated by machinists and CNC programmers in job shop, toolroom, and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard milling applications including slotting, contouring, and full-width cuts on ferrous metals, stainless steel, titanium, and similar hard materials. The centercutting geometry allows plunge entry directly into the workpiece. The AlTiN coating extends tool life at higher surface footage compared to uncoated carbide. Its right-hand cut and right-hand spiral flute configuration suits conventional CNC machining centers and manual knee mills using standard toolholding. The 0.375-inch shank fits common collet chucks, end mill holders, and shrink-fit toolholding systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-temperature performance and extended tool life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with right-hand spiral flute for standard CNC and manual milling setups\u003c\/li\u003e\n\u003cli\u003eDouble-end geometry provides two usable cutting ends, extending service life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 0.375-inch shank via collet chuck, end mill holder, or shrink-fit toolholding.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet or toolholder condition and proper shank seating depth before operation. Follow machine manufacturer torque specifications for drawbar and toolholder fasteners, and confirm runout with a dial indicator before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches (3-1\/2 inch)\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\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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\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: 0.12 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12185046\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755599986994,"sku":"12185046","price":135.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c685b0d56ada0a569a3401d50f0c94b0.jpg?v=1788956646","url":"https:\/\/voomisupply.com\/products\/accupro-12185046-square-end-mill-3-8-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
