Built to the HPHV series standard, it features a 0.75 inch mill diameter, a 1.5 inch length of cut, and a 45-degree chamfer angle with a 0.0200 inch chamfer width. The AlTiN PVD coating extends tool life when cutting ferrous and hard materials at elevated temperatures. With four variable-index flutes and a right-hand cutting direction, it is suited for both roughing and finishing passes. Machinists and CNC operators working with steel, stainless steel, cast iron, and hard materials will find this tool ready for a wide range of milling operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is rated for shouldering, slotting, ramp-down, helical interpolation, drill mill, plunging, and recessing operations. Its centercutting capability allows direct plunge entry without a pre-drilled hole. The Weldon flat shank provides secure tool holding in standard Weldon-style chucks and collet holders. The 4.0 inch overall length provides adequate reach for most production milling setups in vertical and horizontal machining centers running steel, stainless steel, cast iron, and hard-grade workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.0200 inch chamfer width for consistent edge preparation\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for heat resistance and extended tool life in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003eVariable-index, four-flute geometry supports roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank (0.75 inch diameter) for secure, anti-pullout tool retention\u003c\/li\u003e\n  \u003cli\u003eCompatible with shouldering, slotting, ramp-down, helical interpolation, and recessing operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, stainless steel, cast iron, and hard materials (material grade codes P, M, K, H).

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the Weldon flat shank fully into the holder and tighten the set screw against the flat to prevent axial pullout during high-feed passes. Verify runout with a dial indicator before beginning the cut, and confirm cutting parameters are appropriate for the workpiece material and machine rigidity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 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 Width\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HPHV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 4067274\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742329504050,"sku":"4067274","price":730.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99faea544b32b12542f02da3f8aab2eb_f96a2daa-988c-448a-96e3-485e773daff3.jpg?v=1788836799","url":"https:\/\/voomisupply.com\/products\/kennametal-4067274-corner-chamfer-end-mill-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
