It features a 5 mm cutting diameter, a 0.5 mm corner radius, and four right-hand spiral flutes with a 30-degree medium helix angle. The cutting length is 13 mm, with an overall length of 80 mm and a 6 mm straight cylindrical shank. A TiAlN PVD coating provides thermal resistance and wear protection, extending tool life when cutting abrasive or high-temperature materials. This tool is centercutting and handles both roughing and finishing passes in a single setup.\u003c\/p\u003e\u003cp\u003eThe HP434-1961 is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The corner radius geometry reduces edge chipping and stress concentration at the bottom of the cut, making it effective for profile milling, slot milling, and contouring operations in precision machining environments. It mounts in a standard toolholder with a straight-cylindrical shank and is appropriate for CNC machining centers running ferrous and exotic alloy workpieces where tool life and surface finish are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5 mm cutting diameter with 0.5 mm corner radius for reduced edge stress and improved surface finish\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating for elevated heat resistance in steel, stainless, and superalloy cuts\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes with 30-degree medium helix for balanced chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry as well as lateral milling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability in close-tolerance work\u003c\/li\u003e\n\u003cli\u003eHandles roughing and finishing operations across a broad range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-cylindrical bore toolholders.

Confirm toolholder bore cleanliness and proper runout before securing the shank. Avoid overtightening set screws or collet nuts beyond toolholder manufacturer specifications to prevent shank damage. Verify cutting parameters against the workpiece material category before beginning a new operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.5 mm\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: 13 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 80 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.00 to -0.04 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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: HP434-1961\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51751036780850,"sku":"HP434-1961","price":56.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0abe7f41f399f042261e2fc45f2bffd4_09902332-bee8-4e75-867a-2f8cea4c3772.jpg?v=1788921323","url":"https:\/\/voomisupply.com\/products\/osg-hp434-1961-corner-radius-end-mill-5mm-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
