Built on the F3AS series platform, it features a 4 mm cutting diameter, a 0.25 mm corner radius, and three right-hand spiral flutes with a medium helix angle of 35 degrees. The AlTiN PVD coating provides thermal resistance and extended tool life in dry or semi-dry cutting conditions. At 58 mm overall length with a 5 mm length of cut, this is a long-reach configuration suited for deeper pocketing and slotting passes where tool rigidity is critical. Installed by machinists and toolroom operators on CNC milling centers.\u003c\/p\u003e\n\u003cp\u003eThe 4046358 is designed for roughing operations in steel, stainless steel, cast iron, superalloys, titanium, and hard materials — covering ISO material groups P, M, K, S, and H. The coarse pitch flute geometry promotes chip evacuation during aggressive cuts. The 6 mm Weldon flat shank seats securely in ER single angle standard collets and HC hydraulic sleeves with metric bores, making it compatible with a wide range of standard CNC toolholding systems. This single-end configuration is center-cutting, allowing plunge entry where the operation requires it.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade substrate for strength and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating rated for high-heat dry cutting applications including superalloys and hardened steels\u003c\/li\u003e\n  \u003cli\u003e0.25 mm corner radius reduces corner chipping and improves surface finish at pocket edges\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry without a pre-drilled start hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and reduced pullout risk in high-torque roughing conditions\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute spiral with medium 35-degree helix for balanced chip flow and stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ER single angle standard collets and HC 1\/2 through HC 1-1\/4 hydraulic sleeves with metric bores.

Seat the Weldon flat against the toolholder setscrew and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before initiating a cut. Do not exceed the rated length of cut when programming depth-of-cut passes, as overloading the flute length accelerates tool wear and risks breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 4 mm (0.1575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.25 mm (0.0098 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5 mm (0.1969 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 58 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\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 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\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eSeries\u003c\/strong\u003e: F3AS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 4046358\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727197176114,"sku":"4046358","price":103.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab405d32cfd7ab5c1df9a1a6d80afb39.jpg?v=1788674605","url":"https:\/\/voomisupply.com\/products\/kennametal-4046358-corner-radius-end-mill-4mm-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
