Built to the HPHV series specification, this single-end tool features a 0.5000 inch mill diameter, four variable-index flutes with a medium helix, and a 45-degree chamfer angle with a 0.0200 inch chamfer width. The AlTiN PVD coating delivers thermal resistance and extended tool life when cutting ferrous and hard materials. At 2.5 inches overall length with a 0.6250 inch length of cut, this end mill is suited for precision work in both roughing and finishing operations.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use on steel, stainless steel, cast iron, and hard materials (material codes P, M, K, H). Typical applications include shouldering, slotting, ramp-down entry, helical interpolation, drill milling, plunging, and recessing. The Weldon flat shank provides secure tool holding in compatible milling chucks and holders. It is well suited for CNC machining centers in job shop, production, and tool-and-die environments where edge chamfering and multi-purpose milling operations are performed in a single setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree chamfer angle with 0.0200 inch chamfer width for consistent edge preparation\u003c\/li\u003e\n\u003cli\u003eVariable-index flute geometry reduces harmonic vibration during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides thermal resistance for dry or semi-dry cutting in hard and ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute direction with normal pitch for predictable chip evacuation\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank for positive engagement and reduced pull-out risk in high-feed applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner chamfer end mill for use in standard 1\/2 inch Weldon flat tool holders on CNC and manual milling machines.

Ensure the spindle is fully powered down and locked before changing tooling. Secure the Weldon flat shank in a properly sized end mill holder, torquing the set screw to the holder manufacturer's specification. Verify runout with a dial indicator before initiating a cut, and confirm feeds and speeds are appropriate for the workpiece material and machine capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eOverall Length\u003c\/strong\u003e: 2.5000 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\u003eReach Length\u003c\/strong\u003e: 0.6250 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\u003eChamfer Width\u003c\/strong\u003e: 0.0200 inches\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\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: Variable Index\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material\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\u003eSeries\u003c\/strong\u003e: HPHV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.1 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: 4071901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755297669426,"sku":"4071901","price":253.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99faea544b32b12542f02da3f8aab2eb_af4c5af1-ca2d-4f1f-a7f7-adaf93c9edae.jpg?v=1788953269","url":"https:\/\/voomisupply.com\/products\/kennametal-4071901-corner-chamfer-end-mill-1-2-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
