This trigon-shaped insert features an 80-degree included angle, a 0.004-inch corner radius, and an 11-degree relief angle, making it well suited for light to medium finishing cuts where close tolerances and consistent surface finish are required. Grade HT540B with a bright uncoated finish is appropriate for cutting applications where coating is not specified or where the workpiece material benefits from direct carbide contact. Installation is performed by a machinist or tooling technician using the screw-holding method.\u003c\/p\u003e\u003cp\u003eThis insert is used in boring bars and toolholders that accept the WPGT insert style with a 3\/16-inch inscribed circle and 1\/16-inch thickness. It is applicable in job shop and production environments for boring bores in ferrous and non-ferrous materials. The HF1 chipbreaker geometry is designed to promote chip control during light finishing passes. Typical applications include internal diameter finishing on small-bore components in both manual and CNC turning setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWPGT insert style with 80-degree trigon geometry for consistent cutting engagement\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction, material grade C1, for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eHT540B manufacturer grade with bright uncoated finish\u003c\/li\u003e\n\u003cli\u003eHF1 chipbreaker for improved chip control on light finishing cuts\u003c\/li\u003e\n\u003cli\u003eScrew-holding method for positive insert retention in compatible boring bars\u003c\/li\u003e\n\u003cli\u003e0.004-inch corner radius minimizes cutting forces on small, precise bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for boring bars and toolholders accepting WPGT-style inserts with a 3\/16-inch inscribed circle and 1\/16-inch insert thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis insert is installed and replaced by a qualified machinist or tooling technician.
