Built to HP434 series standards, it features a 8 mm cutting diameter with a 0.5 mm corner radius, 4 flutes, and a TiAlN PVD coating that extends tool life at elevated cutting temperatures. The 19 mm length of cut and 100 mm overall length make it well suited for both roughing and finishing passes in a single setup. Right-hand flute direction and right-hand cutting orientation are standard. This tool is installed by machinists and CNC programmers operating vertical and horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThe HP434-3150 is designed for use across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The medium helix geometry and normal pitch support chip evacuation in both slotting and peripheral milling operations. The straight cylindrical shank mounts directly into a standard toolholder. Regular-length classification keeps the tool rigid enough for high-feed passes while maintaining versatility across typical feature depths encountered in job shop and production machining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and heat resistance in ferrous and hard-material cutting\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating improves oxidation resistance and extends tool life at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003e0.5 mm corner radius reduces stress concentration and improves edge durability on workpiece corners\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design simplifies setup in standard toolholder configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-bore toolholders accepting an 8 mm shank diameter with h6 tolerance.

Ensure the machine spindle is fully stopped and the toolholder is properly cleaned before seating the shank. Verify shank clamping torque against the toolholder manufacturer specification before running the program. Confirm cutting direction and spindle rotation are both right-hand before initiating the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 8 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.5 mm (0.0197 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: 19 mm (3.1496 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm, h6 tolerance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.00 to -0.04 mm\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 (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eExtended Reach\u003c\/strong\u003e: No\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, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP434\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.5 inches (L) x 0.5 inches (W) x 0.5 inches (H)\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: HP434-3150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728502128946,"sku":"HP434-3150","price":89.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0abe7f41f399f042261e2fc45f2bffd4_ede758b8-eab2-409e-adbe-4c430dfd1283.jpg?v=1788692267","url":"https:\/\/voomisupply.com\/products\/osg-hp434-3150-corner-radius-end-mill-8mm-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
