It features a 1\/2 inch mill diameter, a 1 inch length of cut, and a 0.02 inch corner radius that reduces stress concentration at the cutting edge and extends tool life. The TiAlN PVD coating adds thermal resistance and hardness, making this tool well-suited for dry and near-dry cutting conditions. With 4 flutes and a medium helix design, it balances chip evacuation with surface finish quality. This end mill is used in CNC machining centers and manual mills by machinists working across production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe HP434-5002 is built for both roughing and finishing operations across a broad range of workpiece materials. It is suited for applications involving steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The single-end, centercutting design allows for plunge entry as well as conventional peripheral milling. Its straight cylindrical shank pairs with standard toolholders used in most CNC setups. This makes it a practical general-purpose tool for shops that machine diverse material types without swapping tool families.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.02 inch corner radius reduces edge chipping and extends tool life in interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating provides thermal hardness for high-speed and dry machining\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral design supports both roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eMedium helix angle balances chip flow and cutting stability across material types\u003c\/li\u003e\n  \u003cli\u003eNormal pitch, no chipbreaker configuration keeps the tool versatile across stock removal rates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-bore toolholders accepting a 1\/2 inch cylindrical shank with h6 shank diameter tolerance.

Seat the shank fully into the toolholder and tighten to the toolholder manufacturer's specified torque using a calibrated wrench. Verify runout at the cutting diameter before beginning production cuts. Coolant-through is not supported on this tool; use external coolant or minimum quantity lubrication as required by the application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.02 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\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: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0015 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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 Material\u003c\/strong\u003e: Steel; Stainless Steel; Cast Iron; Non-Ferrous Metal; Superalloys and Titanium; Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP434\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HP434-5002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":67581784686898,"sku":"HP434-5002","price":164.81,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0abe7f41f399f042261e2fc45f2bffd4_3c761f4b-198d-45c8-9f4b-a1168b443b49.jpg?v=1790406043","url":"https:\/\/voomisupply.com\/products\/osg-hp434-5002-corner-radius-end-mill-1-2-in-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
