TPMT130308-PS T9225 — ISO turning insert, triangular 13 mm, 0.8 mm radius (Tungaloy)

TPMT130308-PS T9225 is an ISO-standard triangular turning insert engineered for robust medium-to-heavy steel turning where variable engagement and short interruptions demand increased toughness.

• ISO-standard triangular insert 13 mm
• CVD-coated carbide grade T9225
• PS chipbreaker for controlled chip formation
• 0.8 mm corner radius, 11° relief angle

Consistent cutting performance with a robust carbide grade

The insert is supplied in a CVD-coated carbide formulation identified by the grade T9225, a robust universal grade designed for medium-to-heavy steel machining. The CVD coating increases wear resistance at elevated temperatures while the substrate provides the necessary toughness when cuts are slightly interrupted or engagement varies. As a result, operators can expect stable tool life and fewer unexpected tool changes, which supports predictable production cycles and efficient use of machine time.

Geometry and seating designed for repeatable accuracy

The triangular 13 mm form and 0.8 mm corner radius are matched to an insert thickness of 3.18 mm and an 11° relief angle, ensuring reliable seating in compatible holders. The insert features a central hole with a cylindrical bore and one-sided countersink (40°–60°) to enable secure clamping and repeatable positioning. Compatibility with a given holder depends on the insert form, relief angle, tolerance class, fastening method, size and thickness, so selection of the correct external holder or boring bar is essential for achieving repeatable accuracy and surface quality.

Effective chip control for safer, faster cycles

Equipped with the PS chipbreaker, this insert manages chip formation and evacuation in a wide range of cutting conditions. The chipbreaker geometry reduces long, stringy chips and promotes short, controllable fragments, lowering the risk of part damage and reducing manual chip handling. Combined with the grade’s wear resistance, improved chip control contributes directly to higher machining throughput and a more reliable surface finish on turned components.

Practical system integration and selection guidance

The typical system includes the ISO insert, an appropriate external holder or boring bar, a shim/clamp set and spare screws. Choose the chipbreaker and grade according to the workpiece material, cutting mode and machine stability: the T9225 grade is the recommended starting point for steel components with variable engagement. For interrupted cuts or heavier feed conditions, the universal toughness of this grade reduces edge chipping and improves process stability, leading to fewer cycle interruptions and better overall productivity.
