Manufactured to the TD6P4 insert style in the HP520B grade, it features a physical vapor deposition (PVD) TiN coating that improves wear resistance and extends tool life in a range of workpiece materials. The insert has a 60-degree included angle with a triangular shape, a 3\/8 inch inscribed circle, 1\/8 inch thickness, a 1\/16 inch corner radius, and an 11-degree relief angle. A screw-clamping hold method keeps the insert securely seated during cutting. This insert is sold individually and requires a minimum order of 10 units.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production and job-shop boring applications where dimensional accuracy and surface finish are critical. The TiN-coated solid carbide construction makes it appropriate for use on ferrous and non-ferrous materials at moderate to high cutting speeds. It is typically installed and indexed by machinists and CNC operators in boring bar toolholders that accept the TD6P4 seat configuration. The HP520B grade and C5 material classification position this insert for general-purpose finish and semi-finish boring passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiN coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003e60-degree triangular insert shape (TD6P4 style) with 11-degree relief angle\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle and 1\/8 inch thickness for stable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003e1\/16 inch corner radius (0.0630 inches decimal) balances edge strength with surface finish quality\u003c\/li\u003e\n\u003cli\u003eScrew-clamping insert holding method for positive, repeatable positioning\u003c\/li\u003e\n\u003cli\u003eHP520B manufacturer grade, C5 material grade, suitable for general-purpose finish and semi-finish boring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit boring insert for toolholders accepting TD6P4 style inserts with a 3\/8 inch inscribed circle and screw-clamping seat geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified torque; do not overtighten, as this can crack the carbide substrate. Inspect the insert pocket and screw threads for debris or damage before seating the new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TD6P4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HP520B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/16 inches (0.0630 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/8 inches (0.1270 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H59875278\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51741765665074,"sku":"H59875278","price":326.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe10160c04fb6021aea661f1b330227f.jpg?v=1788833363","url":"https:\/\/voomisupply.com\/products\/hertel-h59875278-boring-insert-td6p4-hp520b-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
