TPMT 110302 GH730 TPMT — ISO triangular turning insert for turning, 11° clearance by Tungaloy

A TPMT110302-PF GH730 triangular indexable insert designed for external and internal turning applications, combining a wear-resistant cemented carbide grade with a PF chipbreaker for controlled swarf and stable cutting conditions

• ISO-standard triangular insert, chipbreaker PF
• Tungaloy grade GH730 for wear resistance
• 11° clearance angle, 0.2 mm corner radius
• 11 mm inscribed circle, thickness 3.18 mm

Consistent cutting performance through an optimised carbide grade

The insert uses a cemented carbide substrate in the Tungaloy GH730 grade, which combines wear resistance with sufficient toughness to maintain cutting-edge stability under interrupted or continuous cuts. As an indexable turning insert, the result is predictable flank wear and longer intervals between index and replacement, reducing unplanned downtime. The GH730 chemistry and heat treatment are tuned to sustain productive metal removal rates while preserving edge integrity on a wide range of turning tasks.

Geometry and clamping features that support repeatable accuracy

The triangular TPMT shape with a 11 mm inscribed circle and a 3.18 mm plate thickness provides a robust contact area for common external holders and boring bars. The 11° clearance angle and 0.2 mm corner radius aid in controlling cutting forces and surface finish, while the central hole with a cylindrical bore and a single-sided countersink (40°–60°) enables secure clamping and straightforward replacement. Compatibility with a toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness — choose the matching holder and clamping set for best results.

Versatile application and improved chip control for reliable process results

Equipped with a PF chipbreaker, the insert excels in producing short, manageable chips in many turning scenarios, which simplifies chip evacuation in both external and internal turning. The geometry and grade pairing allows selection of the appropriate chipbreaker and cutting parameters according to material, machining type and stability of the set-up. This leads to higher process reliability, better surface quality and efficient machining cycles in batch production or single-part manufacture.

FAQ

What materials is this insert intended for?
The TPMT110302-PF GH730 insert is designed for turning operations where the Tungaloy GH730 grade provides a balance of wear resistance and toughness; selection of chipbreaker and cutting data should match the workpiece material and machining conditions.

How does the PF chipbreaker affect machining?
The PF chipbreaker on the TPMT110302-PF promotes controlled chip formation and easier evacuation, which supports stable cutting and improved surface quality in many turning tasks.

Which holder features are required for correct fitment?
Proper fitment requires a holder matching the insert form, clearance angle (11°), tolerance class, fastening type and the insert’s size and thickness; the central hole with countersink secures the insert in standard clamping systems.

Can this insert be used for internal turning (boring)?
Yes, the insert’s geometry and chip control are suitable for internal turning when used in a compatible boring bar and set-up that provides adequate rigidity.

What is the benefit of the 0.2 mm corner radius?
A 0.2 mm corner radius balances edge strength with the ability to achieve fine surface finishes; it reduces the risk of edge chipping compared with a sharper radius while maintaining reasonable cutting forces.
