CPMT 080204 GT9530 turning insert — coated cermet, rhombic 80° by Tungaloy

A CPMT 080204 GT9530 ISO turning insert designed for finishing and light universal turning of steel under stable machining conditions

• Coated cermet GT9530 for finishing
• Rhombic 80° geometry for versatility
• 0.4 mm corner radius for consistent edge
• Single-sided chipbreaker for stable chips

Achieve consistent surface quality and longer tool life

The coated cermet GT9530 offers a clear benefit where surface finish and extended running time are priorities. The microstructure of a coated cermet reduces flank wear and helps maintain a sharp cutting edge in finishing passes, which results in fewer reworks. For production environments requiring repeatable part quality, this insert provides a measurable advantage: improved finish at comparable cutting parameters and longer tool life in stable setups.

Accurate fit and straightforward mounting for process reliability

Compatibility with the toolholder depends on form, clearance angle, tolerance class, fastening and plate thickness; the ISO designation and rhombic shape simplify selection. The insert features a cylindrical hole with single-sided countersink (40°–60°) and 2.38 mm plate thickness, enabling secure clamping and repeatable seating in standard holders. Correct mounting reduces vibration and helps maintain the 0.4 mm corner radius, delivering consistent part geometry over longer series.

Grade and geometry explained for practical decision-making

This grade is a coated cermet intended as a wear-resistant finishing to light universal grade for steel, giving a balance between surface quality and tool life. The rhombic 80° form provides flexible approach angles, allowing stable cuts during both external and internal turning. The single-sided chipbreaker is tuned for stable chip control in finish operations, keeping the process predictable and reducing the risk of built-up edge.

Practical recommendations for turning applications

Select the CPMT 080204 GT9530 insert when machine rigidity and fixture stability can be ensured; the grade performs best at moderate feeds and finishing speeds where surface integrity is essential. For roughing or unstable setups, consider a more robust universal grade. When switching inserts, verify seat condition and clamp torque to keep repeatability high and avoid premature wear.

System considerations and spare parts planning

A complete system comprises the ISO turning plate, a matching external holder or boring bar, a supporting shim/clamping set and replacement screws. Keeping a small stock of shims and screws avoids downtime during insert changes and supports continuous production. Planning ensures efficient tool management and minimises interruptions in high-mix or volume turning operations.

FAQ

What machining tasks is this insert best suited for?
The CPMT 080204 GT9530 insert is intended for finishing and light universal turning of steel where a good surface finish and extended tool life under stable conditions are required.

Which holders are compatible with this ISO insert?
Compatibility is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness; confirm that the chosen holder accepts a CPMT 080204 geometry and supports the 2.38 mm plate thickness.

How does the GT9530 grade influence cutting performance?
The GT9530 coated cermet grade is designed for wear resistance and fine surface quality, providing longer life in finishing operations compared with uncoated or softer finishing grades.

Is the insert suitable for internal boring as well as external turning?
Yes, the rhombic 80° geometry allows use in both external and internal turning operations, provided the holder geometry and overhang are appropriate for the application.

What key checks are recommended during insertion changeover?
Check seat condition, clamping torque and insert orientation; ensure the cylindrical hole and countersink match the clamping components to maintain repeatability and process reliability.
