With a 3\/8 inch diameter, a 0.03 inch corner radius, and four right-hand spiral flutes, this tool combines edge strength with surface finish capability in a single pass. The TiAlN PVD coating provides thermal resistance and hardness, extending tool life when cutting at elevated temperatures. At 2.5 inches overall length with a 1 inch length of cut, it fits standard toolholders used in vertical machining centers and CNC mills. This tool is installed and used by machinists and tool and die professionals working in precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThe HP434-3753 is suited for both roughing and finishing operations across a wide range of workpiece materials. Its medium helix geometry and normal pitch support stable cutting in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The centercutting design enables plunge entry, adding flexibility in programming. The straight cylindrical shank with h6 tolerance mounts directly into standard collet chucks and shrink-fit toolholders without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03 inch corner radius reduces stress concentration at the cutting edge and improves corner durability\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating rated for high-temperature cutting in ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge milling and ramping operations\u003c\/li\u003e\n\u003cli\u003eFour-flute, right-hand spiral design supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003eMedium helix angle promotes chip evacuation and cutting stability\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker and no coolant-through construction keeps setup straightforward for standard applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard collet, hydraulic, and shrink-fit toolholders accepting a 3\/8 inch straight cylindrical shank.

Ensure the machine spindle is fully stopped and the toolholder is released from the spindle before changing tooling. Verify shank seating depth and runout with a dial indicator before beginning a cut. Consult the machine tool manufacturer and OSG cutting data recommendations for appropriate speeds and feeds for the target material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 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: 1 inch (0.4724 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0015 inches\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\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\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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 Quantity\u003c\/strong\u003e: 1\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: HP434-3753\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733849899314,"sku":"HP434-3753","price":118.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0abe7f41f399f042261e2fc45f2bffd4_822035fa-fb07-43fc-a7c2-199d41951109.jpg?v=1788759586","url":"https:\/\/voomisupply.com\/products\/osg-hp434-3753-corner-radius-end-mill-3-8-in-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
