Part of the T-Max series, this insert features a 60-degree triangle geometry with a neutral hand orientation, making it suitable for a wide range of external and internal turning operations. The substrate is carbide with a CVD-applied TiCN and Al2O3 multilayer coating, grade 3225, which provides wear resistance and thermal stability at elevated cutting speeds. The inscribed circle measures 0.3750 inches and the corner radius is 0.0313 inches, giving machinists a sharp, controlled entry with a rounded cutting edge style. Licensed CNC machinists and turning specialists are the primary installers of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for medium to finishing turning passes in production and job-shop environments. The T-Max series is a widely used platform in steel and alloy steel turning applications. The neutral hand configuration allows flexible toolholder pairing. Maximum depth of cut reaches 15.70 mm, supporting both light finishing and moderate roughing passes. The TPU insert style and clearance code P indicate a positive-geometry toolholder interface, and the tolerance code U designates a standard dimensional tolerance class. This insert is sold individually and is appropriate for shops running high-volume turning operations where consistent insert performance matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD-coated carbide substrate with TiCN and Al2O3 multilayer coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 3225 optimized for steel and general turning applications\u003c\/li\u003e\n  \u003cli\u003e60-degree triangle insert shape with neutral hand for versatile toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 0.3750 inches and corner radius of 0.0313 inches for controlled finishing cuts\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 15.70 mm supporting light roughing through finishing passes\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method with clearance code P and tolerance code U\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-Max series clamp-style turning toolholders that accept TPU-style triangle inserts with clearance code P and tolerance code U.
