TPGT 130304 GH330 turning insert — ISO triangular 60° insert by Tungaloy

The TPGT130304 GH330 is an ISO-standard triangular turning insert designed for general external and internal turning operations where edge stability and wear resistance are required.

• ISO triangular 60° geometry
• GH330 grade carbide substrate
• 0.4 mm corner radius
• 11° clearance angle

Consistent cutting performance from a wear-resistant grade

The GH330 specification combines wear resistance and toughness to give a predictable tool life when machining a wide range of materials. Manufactured in carbide, the insert delivers stable cutting edges that support repeatable turning cycles and reduced downtime for tool changes. The 60° triangular form provides three usable cutting corners, improving cost-efficiency per insert while maintaining consistent chip formation under moderate to stable machining conditions.

Mounting and compatibility for secure clamping

Compatibility with toolholders is determined by the insert’s form, 11° clearance angle, tolerance class, fastening method, size and thickness. The insert sits on a matching ISO holder or boring bar and is secured using the central mounting arrangement; this variant features a cylindrical hole with a single-side countersink (40°–60°) to ensure accurate seating and repeatable clamping. Correct holder selection and correct torque on the clamping screw together ensure reliable performance and reduced vibration during turning.

Geometry and chip control tuned to process stability

With a 0.4 mm corner radius, 3.18 mm thickness and a one-sided chipbreaker, the geometry is balanced for general finishing and medium-duty roughing operations. The chipbreaker design promotes manageable chip flows and reduces edge loading, which helps maintain surface quality and protects the cutting edge. Where higher stability or interrupted cuts are involved, choosing the appropriate chipbreaker form and a more stable clamping arrangement enhances overall process reliability.

Application guidance and system setup

This insert is intended for turning; typical system setup comprises the ISO insert, a compatible external holder or boring bar, a locating pad or clamping kit and replacement screws as required. Select the chipbreaker and the GH330 grade to match the workpiece material and the machining strategy—whether finishing, semi-finishing or light roughing—to balance wear resistance and toughness for longer tool life and consistent surface finish.

FAQ

What materials can this insert machine effectively? The GH330 grade insert is designed as a general-purpose carbide option; the TPGT130304 GH330 insert is suitable for a broad range of materials when the correct chipbreaker and machining parameters are chosen.

How many cutting edges are available on this triangular insert? A triangular insert of this geometry provides three usable cutting edges; rotating to the next corner restores a fresh cutting edge without changing the insert.

What is the purpose of the countersunk mounting hole? The cylindrical hole with a single-side countersink (40°–60°) ensures accurate seating and repeatable clamping in compatible ISO holders, improving stability during turning.

Is the corner radius suitable for finishing operations? The 0.4 mm corner radius offers a good compromise between edge strength and surface finish, making the insert appropriate for finishing and light to medium stock removal.

How should the holder be selected for best results? Choose an ISO holder whose form, tolerance class, fastening and dimensions match the insert; correct holder selection together with the GH330 grade and suitable chipbreaker optimises process stability.
