With a 0.25 inch mill diameter, six flutes, and a 0.020 inch corner radius, this tool delivers precise edge preparation and material removal in a compact geometry. The AlTiN+ coating provides thermal resistance and extended tool life at elevated cutting temperatures. Variable helix and variable index geometry reduce harmonic chatter during aggressive cuts, making this end mill well-suited for tight-tolerance work in difficult-to-machine materials.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for use in high-temperature alloys, the material category designated by workpiece code S. Typical applications include aerospace components, turbine parts, and structural elements machined from nickel-based superalloys, titanium, and similar materials. The center-cutting geometry allows plunge entry, expanding its use in slotting and ramping operations. It is installed and operated by CNC machinists and tool-and-die professionals working on vertical or horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating for high-temperature oxidation resistance and reduced friction\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index design suppresses vibration and chatter\u003c\/li\u003e\n\u003cli\u003eSix-flute configuration increases feed rates and improves surface finish\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable for plunge milling and ramp entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers accepting a 0.25 inch straight shank.

Secure the shank in a collet or end mill holder to the full specified clamping depth before operation. Confirm spindle speed, feed rate, and depth of cut are set according to the material being machined and the toolholder runout specifications. Inspect the cutting edges and coating condition before each use; carbide tools are brittle and should not be dropped or subjected to impact.\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\u003eShank 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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.020 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\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\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\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: 0.07 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: 72055395\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728854319410,"sku":"72055395","price":76.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_fb7767ad-17eb-46e6-a513-0cd11d7d3dbe.jpg?v=1788696903","url":"https:\/\/voomisupply.com\/products\/accupro-72055395-corner-radius-end-mill-1-4-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
