Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), this tool handles elevated cutting temperatures and abrasive workpiece materials. The chipbreaker geometry along the 4 right-hand flutes breaks chips into shorter segments, reducing recutting and heat buildup during aggressive roughing passes. The 3\/8-inch diameter with a 1-inch length of cut and 2-1\/2-inch overall length makes it well-suited to shallow-to-moderate depth roughing in confined or standard-clearance setups.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for roughing operations on steel, stainless, cast iron, titanium, and similar materials. The AlTiN coating extends tool life at higher surface footage where uncoated carbide would degrade rapidly. A 30-degree maximum helix angle balances cutting efficiency with chip evacuation. The right-hand cutting direction and non-center-cutting design mean it is intended for peripheral and side milling, not plunge cutting. Machinists and toolroom professionals running production or job-shop roughing programs will find this a direct-use replacement in standard 3\/8-inch collet or end mill holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for high-heat and abrasion resistance during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eChipbreaker flute geometry reduces chip recutting and lowers cutting forces\u003c\/li\u003e\n  \u003cli\u003e4 right-hand flutes with 30-degree maximum helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eNon-center-cutting, single-end design for peripheral and side milling applications\u003c\/li\u003e\n  \u003cli\u003eRegular length configuration fits standard toolholders without extended-reach clearance issues\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard 3\/8-inch end mill holders, collet chucks, and shrink-fit toolholding systems on CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 3\/8-inch shank fully into the holder and torque the retention mechanism per the toolholder manufacturer specifications. Because this is a non-center-cutting end mill, do not use it for direct plunge cuts into solid material.\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 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Helix 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\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 95168438\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728952164658,"sku":"95168438","price":137.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a24ca3992f04649d737bac83f5817857.jpg?v=1788698012","url":"https:\/\/voomisupply.com\/products\/accupro-95168438-roughing-end-mill-3-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
