It features an 8 mm cutting diameter, a 1.5 mm corner radius, and four flutes with a right-hand spiral and medium helix angle. The tool carries a TiAlN (titanium aluminum nitride) PVD coating, which improves heat resistance and extends tool life when cutting at elevated surface speeds. At 100 mm overall length with a 19 mm length of cut, this single-end, centercutting tool handles both roughing and finishing passes. It is intended for use in CNC machining centers and milling machines with a compatible toolholder.\u003c\/p\u003e\u003cp\u003eThe HP434-3152 is engineered for a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its corner radius geometry reduces stress concentration at the cutting edge, making it well suited for mold and die work, aerospace component machining, and general precision milling where sharp corner chipping is a concern. The straight-cylindrical shank with h6 tolerance fits standard collet and shrink-fit toolholders accepting an 8 mm shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.5 mm corner radius reduces edge chipping and extends tool life in interrupted cuts\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating provides thermal resistance for dry and high-speed machining\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral design supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eNormal pitch with no chipbreaker for smooth chip evacuation in finishing passes\u003c\/li\u003e\n\u003cli\u003e8 mm shank diameter at h6 tolerance ensures secure clamping in precision toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard toolholders accepting an 8 mm straight-cylindrical shank.

Verify toolholder bore cleanliness and runout before securing; excessive runout accelerates edge wear on carbide tooling. Confirm correct collet size or shrink-fit bore of 8 mm before assembly. Do not exceed the toolholder manufacturer's recommended clamping torque range for this shank diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1.5 mm (0.0591 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 19 mm\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.00 to -0.04 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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\u003eTool 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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: HP434-3152\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51735242604850,"sku":"HP434-3152","price":89.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0abe7f41f399f042261e2fc45f2bffd4_af0dc9d0-0c6a-4857-a671-ee37c38c453b.jpg?v=1788770811","url":"https:\/\/voomisupply.com\/products\/osg-hp434-3152-corner-radius-end-mill-8mm-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
