It features an 8 mm cutting diameter, a 0.51 mm corner radius, and five flutes arranged in a right-hand spiral with a high helix angle of 38 degrees. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting at elevated temperatures. With a 19 mm length of cut and 63 mm overall length, this single-end tool suits both roughing and finishing operations in machining centers and CNC mills using ER single angle standard collets.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It belongs to the UCDE series and carries a submicron carbide grade designation, making it appropriate for shops that require consistent performance across a range of ferrous and high-temperature alloy workpieces. The straight-cylindrical shank with an 8 mm diameter fits standard ER collet chucks. Mill diameter tolerance runs from -0.025 mm to -0.047 mm. Shank diameter tolerance is +0.000 mm to -0.009 mm. Material removal type covers both roughing and finishing passes, reducing tool changes in multi-step operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN PVD coating for thermal resistance and extended tool life in steel and superalloy cuts\u003c\/li\u003e\n  \u003cli\u003eFive-flute, right-hand spiral design with 38-degree high helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e0.51 mm corner radius reduces stress concentration and edge chipping at workpiece corners\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide grade supports rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with straight-cylindrical shank fits ER single angle standard collets\u003c\/li\u003e\n  \u003cli\u003eRated for roughing and finishing in one tool across steel, stainless, cast iron, superalloys, titanium, and hard material classifications P, M, K, S, and H\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER single angle standard collets.

Power down and lock out the spindle before inserting or removing the tool from the collet chuck. Ensure the collet and chuck bore are clean and free of chips or coolant residue before seating the shank. Note that this end mill does not support coolant-through delivery, so external coolant or air blast should be directed at the cutting zone during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 19 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.51 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 63 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.025 mm to -0.047 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.000 mm to -0.009 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: UCDE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.117 pounds\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: 3524439\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738652311858,"sku":"3524439","price":157.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f41a7d2274c16c292fb0508ff5b81275_b56113bd-e103-47eb-b2d2-320ebdbefd1c.jpg?v=1788802362","url":"https:\/\/voomisupply.com\/products\/kennametal-3524439-corner-radius-end-mill-8mm-5-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
