TPMT 090208 GT9530 triangular turning insert by Tungaloy — coated cermet, 60° geometry

The TPMT090208 GT9530 is an ISO-standard triangular insert designed for finishing to light universal turning of steel, offering enhanced surface quality and extended tool life under stable machining conditions.

• Coated cermet grade GT9530
• 60° triangular form for versatile turning
• 0.8 mm corner radius for fine finishing

Consistent surface finish and wear-resistant cutting body

The coated cermet GT9530 provides a balance of hardness and toughness that favours excellent surface finish and prolonged tool life in finishing and light turning of steel. Cermet combines ceramic hardness with metal-like toughness, so the insert resists abrasive wear while maintaining cutting-edge integrity at moderate speeds. With a wear-resistant cutting body, the insert reduces the frequency of tool changes and supports steady production runs, which translates into fewer interruptions and improved process reliability.

Clear ISO compatibility and mounting parameters for secure clamping

As an ISO triangular insert, compatibility with the toolholder depends on the insert’s shape, relief angle, tolerance class, clamping method, size and thickness. Key data points are a 60° included angle, an 11° relief (clearance) angle, a 0.8 mm corner radius and a plate thickness of 2.38 mm. The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) for positive seating; these details ensure correct locating and secure fixation in matching holders. When selecting a holder, match the insert seat geometry and tolerances to avoid runout and ensure repeatable positioning.

Productivity gains through stable cutting and reliable chip control

The single-sided chipbreaker and the GT9530 coated cermet grade are intended for stable machining conditions, where consistent cutting forces and controlled chip formation support longer tool life. Improved chip control reduces secondary operations and machine downtime, while the stable cutting edge contributes to a predictable surface quality. For production environments focused on repeatability, the insert’s characteristics help maintain cycle-time consistency and lower the total cost of ownership through fewer tool interventions.

Practical application advice and system composition

Designed primarily for external and internal turning, the insert performs best when combined with an appropriate holder and the correct chipbreaker choice for the workpiece material. The recommended system comprises the ISO insert, a compatible external holder or boring bar, a shim/clamp set and replacement screws for reliable clamping. For finishing passes on steel, pair the insert with moderate feed rates and cutting speeds suited to the machine rigidity and coolant strategy; this preserves the cermet coating’s integrity and secures the expected surface results.
