With a 1\/4 inch (0.2500 inch) diameter and six flutes, it delivers smooth chip evacuation and a fine surface finish. The AlTiN+ coating provides thermal resistance and extended tool life when cutting heat-resistant and high-temperature alloys. A 0.0100 inch corner radius protects the cutting edge and reduces chipping at the tool tip. This end mill is single-end, center-cutting, and features a variable helix and variable index geometry that reduces chatter and improves stability during aggressive cuts. It is sized and specified for use by machinists and tool-and-die professionals working on CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis tool is intended for milling high-temperature alloys (ANSI material code S), including nickel-based and titanium-based superalloys commonly encountered in aerospace, medical, and energy applications. The 1 inch length of cut and 3 inch overall length make it suitable for standard-depth profiling, slotting, and contouring operations. The 1\/4 inch shank diameter fits standard collet toolholders. Right-hand cutting direction and right-hand flute orientation are standard for conventional CNC milling setups. The variable helix geometry is particularly effective at damping harmonics when cutting difficult, gummy materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating for high heat resistance and extended tool life in high-temp alloy machining\u003c\/li\u003e\n\u003cli\u003e6-flute design increases feed rate capability and improves surface finish\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduces chatter and vibration\u003c\/li\u003e\n\u003cli\u003e0.0100 inch corner radius protects cutting edge and extends tool life at the tip\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry into workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in high-temperature alloy (material code S) milling applications.

Ensure the machine spindle is fully stopped and the tool changer or collet is properly locked before installing or removing the end mill. Use a calibrated collet with the correct 1\/4 inch bore to avoid runout. Follow the tooling manufacturer and machine tool OEM guidelines for recommended speeds, feeds, and depth of cut when machining high-temperature alloys.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.0000 inches (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches (76.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0100 inches (0.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN+\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\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy (Code S)\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: 0.07 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: 72054869\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734834053426,"sku":"72054869","price":82.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_a3c76d37-3245-487b-a920-011d806266a7.jpg?v=1788767238","url":"https:\/\/voomisupply.com\/products\/accupro-72054869-corner-radius-end-mill-1-4-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
