Built with a 0.25-inch diameter and six flutes, this single-end mill delivers a 0.5-inch length of cut with a 0.01-inch corner radius. The AlTiN+ coating provides thermal resistance and extended tool life when cutting heat-resistant superalloys and other difficult materials. A variable helix and variable index geometry reduce chatter and improve surface finish compared to standard constant-helix tools. It is center-cutting, allowing plunge entry, and features right-hand cutting and flute direction.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered primarily for High-Temp Alloy workpiece materials, classified under material code S, making it well suited for aerospace, power generation, and precision machining environments where nickel-based and titanium alloys are common. With an overall length of 2.5 inches and a 0.25-inch shank diameter, it fits standard 1\/4-inch collets and tool holders used on CNC machining centers and manual mills. The compact geometry is appropriate for tight-tolerance finishing and semi-finishing passes in small-envelope features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN+ coating for high-heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index design reduces vibration and chatter during cutting\u003c\/li\u003e\n\u003cli\u003eSix-flute configuration increases feed rate capability and improves surface finish\u003c\/li\u003e\n\u003cli\u003e0.01-inch corner radius protects cutting edge and reduces stress concentration at part corners\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance in abrasive workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-temp alloys (material code S) as the primary workpiece material.

Seat the 0.25-inch shank fully and evenly in a clean, properly sized collet or end mill holder before tightening to avoid runout. Inspect the cutting edges and coating for chips or wear before each use, especially when working with high-temp alloys where tool condition directly affects surface integrity. Follow the tooling manufacturer and machine builder recommendations for speeds, feeds, and depth of cut appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\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\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy\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\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: 72052996\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733966881074,"sku":"72052996","price":65.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_e1f060ff-2a7e-495b-a892-096f094c73d3.jpg?v=1788760224","url":"https:\/\/voomisupply.com\/products\/accupro-72052996-corner-radius-end-mill-0-25-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
