It features a 0.5 inch diameter cutting edge with a 1 inch length of cut and a 38-degree helix angle that promotes efficient chip evacuation and reduces cutting forces. The tool is coated with AlTiCrN, a high-performance physical vapor deposition coating that extends tool life in high-heat, high-speed cutting conditions. The micrograin carbide substrate provides hardness and edge retention suited to ferrous and non-ferrous alloys. Licensed machinists and CNC operators are the primary installers of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is built for slot milling, profiling, and contouring operations in machining centers and manual knee mills. The 4-flute spiral configuration supports moderate to high material removal rates while maintaining surface finish quality. The variable index geometry reduces harmonic vibration during cut, making it well suited for side milling and finishing passes on steel, stainless steel, cast iron, and similar materials. Its single-end design allows direct replacement without tool reconfiguration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiCrN coating for extended tool life in high-temperature cutting environments\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes aggressive chip evacuation and reduced cutting force\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and harmonic vibration\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge milling entry\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement end mill for CNC machining centers and manual milling machines accepting a 0.5 inch shank diameter collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC operator. Power down the spindle and confirm zero-energy state before changing tooling. Seat the shank fully into the collet or holder to the manufacturer-recommended engagement depth and torque the retention nut per the toolholder specification. Inspect the cutting edges for chips or coating damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 310281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728847667506,"sku":"310281","price":104.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f44a0f16d6c35f44ed9141083a9c55c.jpg?v=1788696764","url":"https:\/\/voomisupply.com\/products\/accupro-310281-square-end-mill-0-5in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
