With a 0.25 inch mill diameter, six flutes, and a 0.02 inch corner radius, it delivers fine surface finishes while maintaining edge integrity under load. The AlTiN+ coating provides elevated heat and wear resistance, making this tool well suited for cutting high-temperature alloys and other difficult-to-machine materials. It is a single-end, centercutting tool with right-hand flute direction and right-hand cutting direction. Variable index and variable helix geometry reduce chatter and improve chip evacuation during aggressive cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for precision machining operations in aerospace, power generation, and industrial manufacturing environments where high-temp alloys such as Inconel, titanium, and similar materials are commonly machined. The 3\/4 inch length of cut and 2.5 inch overall length suit it for shallow-to-moderate depth passes on milling centers and CNC machining centers. It fits a standard 1\/4 inch tool holder or collet. Machinists and CNC operators working with Series HS tooling will find this geometry appropriate for finishing and semi-finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance at high cutting speeds\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating extends tool life when machining high-temp alloys\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduce harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003e0.02 inch corner radius protects the cutting edge and improves surface finish at corners\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eSix-flute configuration increases feed rate potential and improves finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4 inch tool holders and collet systems on CNC milling machines.

Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Seat the shank fully in the collet or end mill holder and torque the retention hardware according to the tool holder manufacturer specifications. Verify runout with a dial indicator before commencing cuts, as excessive runout accelerates wear on carbide tooling.\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: 0.75 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\u003eCorner Radius\u003c\/strong\u003e: 0.02 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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\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: 72053556\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730220646706,"sku":"72053556","price":64.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_939bc71b-9892-4bd3-b24e-143d90f8fcb2.jpg?v=1788713558","url":"https:\/\/voomisupply.com\/products\/accupro-72053556-corner-radius-end-mill-1-4-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
