Built to the HPHV series specification under material grade KCPM15, it carries a 45-degree chamfer angle and an AlTiN PVD coating that resists heat and extends tool life at elevated cutting speeds. The 1\/2 inch diameter, 4-flute, single-end design with a variable flute index and medium helix style supports both roughing and finishing passes. The Weldon flat shank provides positive drive and minimal slippage in standard end mill holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for machining operations including shouldering, slotting, ramp-down entry, helical interpolation, drill milling, plunging, and recessing. The centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. It is commonly used in CNC machining centers running ferrous and hard-material workpieces in job shop, aerospace, die-and-mold, and general manufacturing environments. A licensed machinist or CNC operator familiar with carbide tooling and HPHV series parameters would be the typical end user.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree chamfer angle for consistent corner geometry on milled features\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides thermal resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eVariable flute index reduces harmonic chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry and helical interpolation\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank for positive drive and secure clamping in end mill holders\u003c\/li\u003e\n  \u003cli\u003eRated for roughing and finishing operations across steel, stainless steel, cast iron, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification solid carbide end mill for use in standard 1\/2 inch end mill holders or collet chucks on CNC machining centers.

Ensure the Weldon flat is properly aligned with the set screw in the holder before torquing. Inspect the tool shank and holder bore for chips or contamination before mounting, as debris will affect runout and tool life. Follow your machine tool manufacturer specifications for clamping torque and confirm cutting parameters against the HPHV series application data before first use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\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: KCPM15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 to -0.00035 inches\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\u003eSeries\u003c\/strong\u003e: HPHV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8.5 x 1.8 x 1.8 inches\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: 4071902\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750479692082,"sku":"4071902","price":270.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99faea544b32b12542f02da3f8aab2eb_e0df05ce-5283-47b6-b2da-859c96eac1ce.jpg?v=1788915762","url":"https:\/\/voomisupply.com\/products\/kennametal-4071902-corner-chamfer-end-mill-1-2-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
