It features an 8 mm cutting diameter with a 1 mm corner radius, a 19 mm length of cut, and a 4-flute right-hand spiral geometry suited for both roughing and finishing operations. The tool is coated with TiAlN via a PVD process, providing elevated heat resistance and extended tool life at higher cutting speeds. A straight-cylindrical 8 mm shank fits standard toolholders, and the 100 mm overall length accommodates a wide range of setups. This end mill is installed and operated by machinists and tooling technicians on CNC milling equipment.\u003c\/p\u003e\n\u003cp\u003eThe HP434-3151 is engineered for use across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It is appropriate for both roughing and finishing passes in a single setup, making it well suited for job shops, production machining, die and mold work, and aerospace component machining where tool versatility across material types is required. The center-cutting design allows plunge entry, adding flexibility in toolpath programming.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for high-temperature performance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e1 mm corner radius reduces stress concentrations and improves edge durability on workpiece corners\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral geometry with normal pitch supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eMedium helix style balances chip evacuation and cutting force across multiple material groups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard cylindrical-bore toolholders accepting an 8 mm straight shank.

Confirm the toolholder bore and collet size match the 8 mm shank diameter and adhere to shank diameter tolerance class h6 before seating. Power down and lock out the spindle before installing or removing the tool. Do not exceed the manufacturer-recommended runout tolerance for the toolholder, as excess runout accelerates edge wear on carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 8 mm (0.3150 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1 mm (0.0394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 19 mm (1.8898 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100 mm (3.937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm, tolerance h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees, Medium style\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, Single End, Center-Cutting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Normal Pitch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.00 to -0.04 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\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: HP434-3151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738454065458,"sku":"HP434-3151","price":89.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa89787cf06330e23d6163fbe92ad928.jpg?v=1788799707","url":"https:\/\/voomisupply.com\/products\/osg-hp434-3151-corner-radius-end-mill-8mm-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
