This uncoated triangular insert carries a 60-degree included angle, a 15-degree relief angle, and a 0.007-inch corner radius, making it well suited for finishing passes and tight-tolerance bores where edge sharpness and dimensional control are critical. The insert is manufactured to material grade C25 and carries manufacturer grade HT310B. At 0.0469 inches thick with a 5\/32-inch (0.1563-inch) inscribed circle, it is a compact insert intended for small-bore toolholders. Installation is by screw-clamp holding method. Machinists and tooling specialists install and index this insert on the shop floor or in the field.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in metalworking applications where internal diameter boring of ferrous and non-ferrous materials is required. The uncoated solid carbide construction makes it appropriate for applications where a coated insert would mask edge geometry or where re-grinding is part of the tooling program. Typical install scenarios include production turning cells, job-shop lathes, and boring bar setups requiring a small inscribed circle. The screw-clamp holding method provides positive insert retention during interrupted and continuous cuts alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction, material grade C25, for rigidity and wear resistance in boring applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish preserves sharp cutting edge geometry for finishing and close-tolerance work\u003c\/li\u003e\n  \u003cli\u003e60-degree triangle shape (TDHB insert style) with 15-degree relief angle reduces cutting forces on small-bore setups\u003c\/li\u003e\n  \u003cli\u003e0.007-inch corner radius suited for fine-finish internal boring passes\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch (0.1563-inch) inscribed circle fits compact boring bar toolholders\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for secure, repeatable indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-fit insert for screw-clamp boring bar toolholders accepting a triangular insert with a 5\/32-inch inscribed circle and TDHB insert style designation.

Use the correct torque driver or wrench specified by the toolholder manufacturer for the clamp screw  -  do not overtighten, as solid carbide inserts are brittle and will crack under excessive clamping load. Inspect the insert pocket seat for chips or debris before seating a new insert. Dispose of worn inserts per facility carbide recycling procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TDHB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1.280.75.0.5\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: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.007 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/32 inches (0.1563 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/64 inches (0.0469 inches)\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: C25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HT310B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: H59873398\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740829221170,"sku":"H59873398","price":245.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0753a916ddeefe97f2696d7de25e0ddf.jpg?v=1788827681","url":"https:\/\/voomisupply.com\/products\/hertel-h59873398-boring-insert-triangle-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
