With a 4 mm cutting diameter, 1 mm corner radius, and four flutes, it delivers a blend of material removal efficiency and surface finish quality in a single tool. The TiAlN (titanium aluminum nitride) PVD coating extends tool life by resisting heat and wear at elevated cutting speeds. At 70 mm overall length with an 11 mm length of cut and a 6 mm straight-cylindrical shank, this is a compact, rigid tool suited for die-and-mold work, aerospace components, and precision machined parts. Licensed machinists and CNC operators install and run this tool in standard toolholders.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for roughing and finishing operations across a broad range of workpiece materials. Its centercutting geometry allows plunge entry, and the right-hand spiral flute design with medium helix promotes chip evacuation and stable cutting action. Typical applications include profiling, slotting, and contouring in ferrous and non-ferrous materials where corner integrity and dimensional accuracy are critical requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 mm cutting diameter with 0.00 \/ -0.04 mm mill diameter tolerance for precise dimensional control\u003c\/li\u003e\n\u003cli\u003e1 mm corner radius protects the cutting edge and improves surface finish at part corners\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating provides heat resistance and extended tool life at high cutting speeds\u003c\/li\u003e\n\u003cli\u003eFour-flute, right-hand spiral design supports both roughing and finishing in a single pass\u003c\/li\u003e\n\u003cli\u003eCentercutting construction allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with h6 tolerance fits standard CNC toolholders securely\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-bore CNC toolholders accepting a 6 mm shank.

Verify the toolholder bore and collet size match the 6 mm shank diameter before clamping. Use a torque wrench appropriate to the toolholder manufacturer specification when securing set screws or collet nuts. Inspect the corner radius and cutting edges for chips or wear before each setup, as carbide tools are brittle and should not be used if edge damage is visible.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.00 mm (0.0394 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: 11.00 mm (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.00 \/ -0.04 mm\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\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: HP434-1577\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731711557938,"sku":"HP434-1577","price":50.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/84c554595a872abce5a8e9cc6d5cb2a4.jpg?v=1788734148","url":"https:\/\/voomisupply.com\/products\/osg-hp434-1577-corner-radius-end-mill-4mm-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
