With a 1\/4 inch diameter, a 3\/4 inch length of cut, and 5 helical flutes, this single-end tool is engineered for efficient chip evacuation and surface finish quality. The AlTiN coating provides thermal resistance and hardness at elevated cutting temperatures, extending tool life in abrasive and hard-material applications. The 43-degree helix angle promotes smooth cutting action and reduces radial cutting forces during the milling operation.\u003c\/p\u003e\n\u003cp\u003eThis end mill head is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials in both roughing and finishing passes. The right-hand flute direction and right-hand cutting orientation make it compatible with standard CNC machining center spindles. The straight shank measures 1\/4 inch in diameter, matching the mill diameter for direct toolholder engagement. This tool is typically installed and applied by machinists and CNC programmers working in job shop, aerospace, die and mold, and general metalworking environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and hard-material cutting\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating extends tool life in high-temperature and abrasive machining conditions\u003c\/li\u003e\n  \u003cli\u003e5-flute helical design improves chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003e43-degree helix angle reduces cutting forces and chatter during milling\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with right-hand cut and right-hand flute direction\u003c\/li\u003e\n  \u003cli\u003eNo chipbreaker, no coolant-through design — suited for external coolant delivery setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the KENNAMETAL HARVI UGDE series.

Power down and lock out the machine spindle before inserting or removing the tool head. Ensure the toolholder bore and clamping mechanism are clean and free of debris before seating the shank. Confirm runout with a dial indicator after clamping to avoid premature edge wear or dimensional inaccuracy.\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: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 43 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KC643M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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: No\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HARVI UGDE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 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: 5059453\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739178041650,"sku":"5059453","price":151.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd89dd2e4a8398d3c5ff2aba3897acbf_8178b1df-e471-46ac-9189-36f1284b6b06.jpg?v=1788810866","url":"https:\/\/voomisupply.com\/products\/kennametal-5059453-corner-radius-end-mill-head-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
