Built to a 1\/4 inch (0.2500 inch) diameter with a 0.0600 inch corner radius, it features six flutes with a variable helix and variable index geometry. The AlTiN+ coating provides elevated heat resistance and extended tool life at cutting speeds typical of high-temperature alloy work. This is a single-end, center-cutting tool with right-hand flute direction and right-hand cutting action. It is installed and used by machinists and CNC operators in precision metalworking environments.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for primary use in high-temperature alloys, classified under workpiece material code S. That includes nickel-based superalloys, titanium, and similar difficult-to-machine materials common in aerospace, medical, and energy-sector component manufacturing. The 1-1\/4 inch length of cut and 3 inch overall length make it well suited for moderate-depth pocket milling, slotting, and profiling operations where a 1\/4 inch shank toolholder is in use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSix-flute variable helix design reduces harmonics and chatter in high-temp alloy cuts\u003c\/li\u003e\n\u003cli\u003eVariable index spacing distributes cutting forces evenly across the flute set\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating delivers oxidation resistance and hardness at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e0.0600 inch corner radius protects the cutting edge and improves surface finish at part corners\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry without a pre-drilled start hole\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance over extended run times\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\/4 inch collet or end mill holder.

Always power down and lock out the spindle before loading or changing tooling. Follow the machine tool manufacturer guidelines and applicable shop safety codes when setting cutting parameters for carbide end mills in high-temp alloys. Inspect the corner radius and cutting edges for chipping after each use in abrasive or work-hardening materials.\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\u003eShank 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: 1.2500 inches (31.75 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\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches (1.52 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\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\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: 0.07 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: 72056054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736821956914,"sku":"72056054","price":84.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_a89a3f04-11fe-4569-9d30-fbe2bc8666fc.jpg?v=1788780769","url":"https:\/\/voomisupply.com\/products\/accupro-72056054-corner-radius-end-mill-1-4-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
