Built on the HPHV series platform, this single-end, four-flute tool measures 0.75 inches in diameter with a 1.625-inch length of cut and a 4-inch overall length. The 45-degree chamfer geometry with a 0.0200-inch chamfer width produces clean edge breaks and transitions in a single pass. An AlTiN PVD coating provides thermal resistance and extended tool life when cutting ferrous and hard materials. The variable flute index and center-cutting capability make it suitable for both roughing and finishing operations. Licensed machinists and CNC tooling specialists are the primary installers and operators of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is rated for use on steel, stainless steel, cast iron, and hard materials. It supports a wide range of machining operations including shouldering, slotting, ramp-down, helical interpolation, drill milling, plunging, and recessing. The Weldon flat shank accommodates standard side-lock toolholders commonly found in vertical and horizontal machining centers. The normal pitch and medium helix style balance chip evacuation with surface finish across this broad material range. It is suited for both prototype shops and production environments requiring a single tool capable of multiple operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction, KCPM15 material grade, for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for thermal protection when cutting steel, stainless steel, cast iron, and hard materials\u003c\/li\u003e\n  \u003cli\u003e45-degree chamfer angle with 0.0200-inch chamfer width for consistent edge preparation\u003c\/li\u003e\n  \u003cli\u003eVariable flute index reduces harmonic vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design enables plunging and helical interpolation without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and reduced pullout risk in side-lock holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and right-hand cutting for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/4-inch side-lock or Weldon flat toolholders on CNC vertical and horizontal machining centers.

Ensure the machine spindle is fully stopped and the tool path program is verified before loading the tool into the holder. Seat the Weldon flat fully against the set screw and torque per the toolholder manufacturer's specification. Confirm runout with a dial indicator before initiating any cutting cycle, as excessive runout will accelerate wear and reduce chamfer accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.6250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7500 inches\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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute 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\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\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: 4067280\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736961679666,"sku":"4067280","price":805.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/99faea544b32b12542f02da3f8aab2eb_987f115c-5281-4e96-943c-0e96f84b1542.jpg?v=1788782420","url":"https:\/\/voomisupply.com\/products\/kennametal-4067280-corner-chamfer-end-mill-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
