It carries a 0.750-inch mill diameter with a 0.015-inch corner radius and features five right-hand spiral flutes with a high helix angle of 43 degrees. The AlTiN PVD coating extends tool life in high-temperature cutting environments. At 5 inches overall length with a 2.25-inch length of cut and extended reach, this single-end tool handles both roughing and finishing operations. It belongs to KENNAMETAL Series UGDE and is produced from submicron-grade carbide for edge stability under load.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers in aerospace, die and mold, and general metalworking applications where a combination of reach and corner integrity is required. The straight cylindrical shank at 0.750 inches is compatible with HC-HSK Form A, Hydraulic Chuck Standard Line Inch KM63XMZ, and HC-CV Form AD toolholding systems. It is not center-cutting, so it is intended for peripheral and side milling passes rather than plunge entry. Normal pitch and fixed helix geometry provide predictable chip evacuation across the listed workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.015-inch corner radius protects the cutting edge and improves surface finish at shoulders and steps\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides oxidation resistance and thermal hardness for dry or near-dry cutting in hard materials\u003c\/li\u003e\n\u003cli\u003e5-flute configuration increases feed rate potential compared to 4-flute designs in the same diameter\u003c\/li\u003e\n\u003cli\u003eHigh 43-degree helix promotes efficient chip evacuation and reduces cutting forces in long-reach applications\u003c\/li\u003e\n\u003cli\u003eExtended reach design at 2.25 inches LOC suits deep pocket and cavity milling\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade delivers consistent edge wear performance in ferrous and exotic alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible toolholding systems include HC-HSK Form A, Hydraulic Chuck Standard Line Inch KM63XMZ, and HC-CV Form AD.

Ensure the machine spindle is fully stopped and the tool is secure in a compatible toolholder before tightening. Verify runout at the tool tip before beginning a cut, as extended-reach end mills are sensitive to toolholder concentricity. Consult the machine tool manufacturer and KENNAMETAL cutting data recommendations for appropriate speeds, feeds, and depth of cut for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\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: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 43 degrees\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\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\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00051 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: UGDE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.001 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5059743\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738271842610,"sku":"5059743","price":923.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1d6ad24eafd93860243daaefb775615_853b9ceb-8994-4858-8261-9b12036d2acd.jpg?v=1788797468","url":"https:\/\/voomisupply.com\/products\/kennametal-5059743-corner-radius-end-mill-3-4in-5-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
