This single-sided, diamond-shaped insert features a bright uncoated finish, a C2 carbide grade, and a positive rake geometry with a flat top chip breaker. At 0.25 inches thick with a 0.5512-inch inscribed circle, it delivers consistent cutting performance in screw-held toolholders. The neutral hand orientation makes it adaptable across standard insert-seat configurations. It is installed by CNC machining technicians and production tooling specialists.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for cutting particleboard, MDF, and balsa wood, making it well suited for cabinetry, furniture component manufacturing, sign-making, and similar high-volume woodworking production environments. The VGPT insert style and Series 91-000 and 91-100 cutter series compatibility make it a direct fit for existing ONSRUD tooling setups. Maximum depth of cut is 0.125 inches. The flat top chip breaker geometry helps manage chip flow in abrasive engineered wood substrates where edge retention is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide C2 grade construction for durability in abrasive wood composites\u003c\/li\u003e\n  \u003cli\u003eDiamond insert shape (VGPT style) with positive rake for clean, efficient cuts\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for dry cutting of particleboard, MDF, and balsa\u003c\/li\u003e\n  \u003cli\u003eFlat top chip breaker for controlled chip evacuation in high-feed applications\u003c\/li\u003e\n  \u003cli\u003e7-degree relief angle with neutral hand for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eScrew-held insert mounting for secure, repeatable seating in the cutter body\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with ONSRUD Series 91 cutter bodies, including the Series 91-000 and Series 91-100 lines.
