With a 1\/4-inch cutting diameter and a 1\/2-inch length of cut, this single-end mill operates in right-hand cutting and right-hand flute direction. The three-flute spiral geometry and high helix angle promote efficient chip evacuation and surface finish quality. At 2.5 inches overall length with a straight cylindrical 1\/4-inch shank, it fits standard tool holders and hydraulic sleeves used in CNC machining centers. Machinist and tooling technicians working with aluminum, brass, copper, and similar non-ferrous stock are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for short-reach roughing operations on non-ferrous metals in both production and job-shop CNC environments. The AADE series designation places it in a coarse-pitch, submicron carbide grade family optimized for high material removal rates without coating. It is centercut capable, allowing plunge entry in addition to peripheral and slot milling. Compatible tooling systems listed in the input include HC 1\/2 through HC 1-1\/4 hydraulic sleeves inch with inch bores and HC 20M through HC 32M hydraulic sleeves metric with inch bores.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron material grade for rigidity and wear resistance in non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003eCorner radius end type reduces stress concentration at cutting edges compared to sharp-corner geometry\u003c\/li\u003e\n  \u003cli\u003eThree-flute spiral configuration with coarse pitch supports aggressive roughing chip loads\u003c\/li\u003e\n  \u003cli\u003eHigh helix angle promotes smooth cutting action and efficient chip flow in aluminum and similar materials\u003c\/li\u003e\n  \u003cli\u003eCentercut capable — supports plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup concerns when machining non-ferrous materials that can react with TiN or TiAlN coatings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with HC 1\/2 through HC 1-1\/4 hydraulic sleeves inch with inch bores and HC 20M through HC 32M hydraulic sleeves metric with inch bores.

Ensure the machine spindle is fully stopped and the tool changer is in a safe state before inserting or removing the end mill. Confirm shank seating depth and runout with a dial indicator before production cuts. Do not exceed the manufacturer-rated depth of cut for the tool diameter and material combination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 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: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AADE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.062 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.5 inches (L) x 2 inches (W) x 2 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3870455\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51746173026610,"sku":"3870455","price":89.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0dc924105dae23d87ca947c9192419b5_1a03b5ff-f56a-4b4b-a2a3-dd66e90aa895.jpg?v=1788866720","url":"https:\/\/voomisupply.com\/products\/kennametal-3870455-corner-radius-end-mill-1-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
