CPMT090308 TH10 CPMT indexable insert for turning by Tungaloy — 80° rhombic, 0.8 mm radius

The CPMT090308 TH10 is an ISO‑standard indexable insert designed for turning operations, optimised for non‑ferrous materials and applications where a sharp, uncoated cutting edge reduces cutting forces and improves surface finish

• Uncoated carbide for low cutting forces
• Sharp TH10 grade for non‑ferrous materials
• 80° rhombic geometry for versatile turning
• 0.8 mm corner radius for robust edge integrity

Higher throughput with lower cutting forces

The combination of a sharp TH10 grade and uncoated carbide substrate delivers a cutting edge that minimises built‑up edge and reduces cutting resistance when machining aluminium, copper alloys and other non‑ferrous materials. Reduced cutting forces translate directly into quieter operation, lower spindle load and the potential for increased feed rates while maintaining a clean surface finish. For production environments seeking measurable productivity gains, this cutting‑edge geometry provides a reliable efficiency improvement without complex process changes.

Geometry engineered for precision and repeatability

The 80° rhombic form with a 0.8 mm corner radius and 11° clearance offers a balance between edge strength and accessibility for external and internal turning. The standardised ISO shape ensures predictable cutting behaviour and repeatable results across holders and machines. The single‑sided chipbreaker is optimised for continuous chips typical of non‑ferrous machining, promoting stable chip control and reducing the risk of surface damage. Together, these features simplify process setup and support consistent dimensional accuracy.

Easy system integration and secure fastening

Compatibility with holders depends on form, clearance angle, tolerance class, fixing method, size and thickness; the insert’s ISO designation CPMT090308 and a cylindrical hole with one‑sided countersink (40°–60°) facilitate secure clamping in a wide range of external holders and boring bars. The 3.18 mm thickness and standardised locating geometry make tool changes fast and predictable, reducing downtime during production swaps. Selecting a matched clamping kit and replacement screws ensures repeatable seating and optimal cutting performance.

Practical handling and grade selection guidance

The uncoated, universal TH10 grade is intended for applications where a sharp, clean edge is preferable to coated alternatives — typically short‑to‑medium runs in non‑ferrous materials or mixed shops requiring low cutting forces. The insert’s robustness supports stable machining even under variable feed conditions, while its ISO conformity assists in choosing the correct counterpart holder. For operations requiring extended tool life under higher thermal loads, a coated grade may be considered; for clean finishes and minimal cutting force, the supplied grade is appropriate.

FAQ

What materials is this insert suited for?
The CPMT090308 TH10 insert is optimised for non‑ferrous materials such as aluminium and copper alloys; the uncoated TH10 grade reduces built‑up edge and supports clean surface finishes.

Can this insert be used in standard ISO holders?
Yes. The ISO designation CPMT090308 and the standard hole and thickness enable use in compatible ISO‑type external holders and boring bars when the holder matches form, tolerance class and clamping style.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius improves edge strength and stability compared with finer radii, providing greater robustness during interrupted cuts while still offering good surface quality.

Is the CPMT090308 suitable for finishing passes?
The sharp uncoated cutting edge of the TH10 grade delivers excellent surface finish in finishing operations on non‑ferrous materials, provided cutting parameters are tuned to the workpiece and machine stiffness.

What fastening does the insert require?
The insert features a cylindrical hole with a one‑sided countersink (40°–60°) and is secured using the matching screw and clamping kit specified for the chosen holder style.
