Built from micrograin solid carbide and coated with AlCrTiN, it handles demanding cuts where heat resistance and edge retention are critical. The 0.020-inch corner radius reduces stress concentration at the cutting edge, extending tool life in interrupted and continuous cuts. With a 38-degree helix angle, five flutes, and a variable index design, this end mill promotes smooth chip evacuation and reduces chatter at aggressive feed rates. It is centercutting, allowing plunge entry, and runs in a right-hand cutting and right-hand flute direction.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for precision machining operations including profiling, slotting, and finishing passes on ferrous metals, stainless steels, and high-temperature alloys. The AlCrTiN coating performs well at elevated cutting temperatures, making it a practical choice for dry or minimal-lubrication machining environments. It is intended for use in CNC machining centers, vertical mills, and similar equipment where a 1\/2-inch straight shank toolholder is available. Machinists and tool-and-die professionals will find it appropriate for production and maintenance machining applications requiring tight tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating for heat resistance in high-speed and dry machining\u003c\/li\u003e\n\u003cli\u003e0.020-inch corner radius reduces edge chipping and stress concentration\u003c\/li\u003e\n\u003cli\u003eFive-flute, variable index design reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003e38-degree helix promotes efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with a 1\/2-inch straight shank toolholder.

Ensure the machine spindle and toolholder are fully powered down and locked out before changing tooling. Seat the shank fully into a clean, undamaged collet or endmill holder to the recommended gauge-line depth for the holder type in use. Verify runout with a dial indicator before initiating a cut, and confirm feed, speed, and depth-of-cut parameters are appropriate for the workpiece material before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches (50.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (101.6 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: 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: 311674\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732071383346,"sku":"311674","price":158.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bd2a8e3f446a8fadb7d1571c76120dd.jpg?v=1788738873","url":"https:\/\/voomisupply.com\/products\/accupro-311674-corner-radius-end-mill-1-2-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
