Built from micrograin carbide and coated with AlTiN (aluminum titanium nitride), it handles high-heat cutting environments where tool life and edge retention are critical. The 1\/2 inch diameter cutter features 4 flutes with a 0.04 inch corner radius, a 5\/8 inch length of cut, and a 2-1\/2 inch overall length. It is center-cutting and runs in a right-hand cutting, right-hand flute configuration. Machinists and tool-and-die professionals install this tool in CNC milling machines and machining centers for roughing passes on ferrous and hardened materials.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations in both production and job-shop environments. The stub-length configuration provides increased rigidity, making it effective for slotting, pocketing, and peripheral milling where chatter and deflection are concerns. The AlTiN coating improves performance in dry or semi-dry cutting conditions and extends tool life when machining steel, stainless steel, and cast iron. The 1\/2 inch shank diameter fits standard ER and end mill holders used across most CNC milling platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for high hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for thermal protection in high-speed and dry cutting\u003c\/li\u003e\n\u003cli\u003e4 flutes with 0.04 inch corner radius to reduce edge chipping and improve surface finish on roughing passes\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eStub-length flute configuration maximizes rigidity and reduces deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003ePart of the HPRST series, designed for high-performance roughing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard 1\/2 inch end mill holders, ER collet chucks, and hydraulic or shrink-fit toolholders on CNC vertical and horizontal milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated to the recommended gauge-line depth in the holder and that holder set screws or collet nuts are torqued according to the toolholder manufacturer specifications. Inspect the cutting edges and corner radius for chips or wear before each use; damaged carbide tooling should not be run.\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0400 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: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 to -0.00043 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.002000 to -0.006300 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: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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: HPRST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 3331485\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734251995442,"sku":"3331485","price":380.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50628e7311c5cbed1f39bde6f85857e5.jpg?v=1788761528","url":"https:\/\/voomisupply.com\/products\/kennametal-3331485-roughing-end-mill-1-2-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
