It features a 3\/4-inch diameter with a 0.250-inch corner radius and a 5-flute, right-hand spiral configuration with a variable index for improved chip evacuation and reduced chatter. The 38-degree helix angle promotes smooth cutting action across a range of ferrous and non-ferrous materials. An AlCrTiN coating provides high heat resistance and extended tool life in demanding cutting conditions. This is a single-end, centercutting tool capable of plunge entry, making it suitable for slotting, profiling, and pocket milling. Machinists and CNC operators in job shops, aerospace, and precision manufacturing install and apply this type of end mill.\u003c\/p\u003e\u003cp\u003eThis end mill is built for use in CNC machining centers and manual milling machines where a corner radius profile is required to reduce stress concentrations in milled pockets and contoured features. The 1.625-inch length of cut and 4-inch overall length make it well suited for moderate-depth milling passes in steel, stainless steel, titanium, and similar hard materials. The micrograin solid carbide construction supports high-speed and high-feed applications where tool rigidity and edge retention are critical. A 3\/4-inch shank diameter allows direct collet or end mill holder mounting in standard tooling systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-inch mill diameter with 0.250-inch corner radius for stress-reducing edge profiles\u003c\/li\u003e\n\u003cli\u003e5-flute variable-index design reduces harmonic vibration during high-speed cuts\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating delivers high thermal resistance and extended edge life in hard materials\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes efficient chip flow and smooth surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 3\/4-inch shank end mill in ER, CAT, BT, or HSK toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed and changed by machinists following shop safety procedures and machine lockout\/tagout protocols. The spindle must be fully stopped and the machine powered down before tool changes. Use a calibrated torque wrench and appropriate collet or end mill holder to secure the shank to the manufacturer-recommended clamping specification for your toolholding system. Inspect the cutting edges for chipping before each use and discard or regrind the tool if edge damage is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 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\/4 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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: AlCrTiN\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\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: 311796\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730623430962,"sku":"311796","price":375.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6067b27c111a743c6d45fd9e4aaf5910.jpg?v=1788720443","url":"https:\/\/voomisupply.com\/products\/accupro-311796-corner-radius-end-mill-3-4-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
