TPMT 110304 GH730 — TPMT110304-PM GH730 triangular ISO turning insert by Tungaloy

TPMT110304-PM GH730 is an ISO-indexed triangular turning insert designed for general turning applications where reliable chip control and stable edge life are required

• ISO-indexed triangular insert TPMT format
• GH730 grade: wear-resistant carbide
• PM chipbreaker for stable chip control
• 0.4 mm corner radius, 11° relief angle

Consistent productivity through optimised grade and geometry

The combination of an ISO-indexed triangular format and the GH730 cutting grade provides a balance between wear resistance and edge stability that supports continuous production runs. The PM chipbreaker is engineered to promote reliable chip formation under varying cutting conditions, which reduces the risk of process interruptions. Compatibility with the toolholder is defined by form, relief angle, tolerance class, fastening method, size and thickness, so the insert’s dimensions and central hole ensure repeatable clamping and positional accuracy. These design choices translate into fewer unplanned stops and a steadier part output.

Precision cutting edge for reproducible surface quality

A small 0.4 mm corner radius and an 11° relief angle contribute to a stable cutting edge and predictable cutting forces, helping to maintain surface finish consistency across components. The triangular shape with a nominal 11 mm size and a 3.18 mm plate thickness creates a rigid seating area that supports moderate depths of cut while limiting insert deformation. The central hole with a cylindrical bore plus single-sided countersink (40°–60°) ensures secure fastening and concentric seating in compatible holders. Overall, the geometry supports reproducible results and simplifies process documentation for batch production.

Process guidance and material-adaptable performance

Intended for turning operations, the indexable plate is supplied in a carbide substrate tailored by Tungaloy to achieve a good compromise between hardness and toughness. The PM chipbreaker and the GH730 composition allow selection of feed and speed combinations according to workpiece stability and machining strategy; choose the chipbreaker and grade to match the specific material and operational rigidity. For internal and external turning tasks the system approach—insert combined with a matching outer holder or boring bar, clamp kit and replacement screws—ensures that the insert functions as part of a robust cutting assembly that is easy to document and repeat across setups.

FAQ

What applications suit this insert best? This insert is designed for turning operations; the TPMT110304-PM GH730 plate is suitable for both external and internal turning when matched with an appropriate holder and operating parameters.

How does the PM chipbreaker affect machining? The PM chipbreaker promotes controlled chip formation and evacuation under a range of cutting conditions, improving process stability and reducing the likelihood of built-up edge.

What determines compatibility with a toolholder? Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; the TPMT110304-PM format and central hole specification are key for correct clamping.

How does the corner radius influence results? A 0.4 mm corner radius provides a compromise between edge strength and surface finish, supporting consistent part quality while maintaining acceptable cutting forces.
