CPMT 090308 T505 — CPMT090308 T505 Tungaloy indexable turning insert for Drehen

CPMT090308 T505 Tungaloy is an ISO‑standard indexable turning insert designed for economical and reliable machining of cast iron in external and internal turning applications

• CVD‑coated carbide for cast iron
• ISO CPMT090308 geometry
• Single‑sided chipbreaker
• Cylindrical hole with countersink

Higher material removal rates for cast iron with consistent tool life

The CVD‑coated carbide grade T505 is tuned for the demands of cast iron machining: the coating improves thermal and abrasive resistance while the substrate maintains edge strength. This combination delivers stable chip formation and improved wear resistance, which translates into fewer insert changes and higher uptime on production runs. For shops seeking a balance between cost and productivity, the economic behaviour of this grade supports longer tool life without sacrificing surface quality.

Secure mounting and standardised geometry for repeatable results

ISO conformity of the CPMT090308 geometry ensures straightforward selection of compatible holders and simple replacement routines. Critical dimensions such as the 3.18 mm plate thickness, rhombic shape and the 11° relief angle influence seating, chip flow and cutting forces; matching these values with the clamp and tolerance class reduces vibration and improves repeatability. The insert’s cylindrical hole with a one‑sided countersink (40°–60°) gives a reliable clamping interface that supports consistent concentricity and repeatable positioning, especially important in batch production.

Practical guidance on chip control and edge geometry for process stability

The single‑sided chipbreaker is designed to support controlled chip breaking in stable setups; selecting this chipbreaker and the 0.8 mm corner radius helps achieve the desired balance between surface finish and tool strength. For interrupted cuts or unstable set‑ups, choose a more robust holder and consider a grade and chipbreaker combination matched to workpiece stability. The insert is intended for turning operations where chip evacuation and controlled cutting forces are priorities, enabling efficient machining with predictable results.

FAQ

What materials is this insert optimised for?
The CPMT090308 T505 insert is optimised for cast iron applications; the T505 grade and CVD coating provide abrasion resistance suited to grey and nodular cast irons.

How does the insert attach to a holder?
The insert uses a cylindrical hole with a one‑sided countersink (40°–60°) for positive clamping; matching the holder to the ISO geometry and tolerance class ensures secure seating and repeatable positioning.

Is the chipbreaker suitable for interrupted cuts?
The single‑sided chipbreaker on this insert provides controlled chip formation in stable cutting conditions; for aggressive interrupted cuts a different chipbreaker or a more robust setup is recommended.

What benefits does the CVD coating deliver?
The CVD‑coating increases thermal and abrasive resistance at the cutting edge, which improves tool life and helps maintain a consistent surface finish during extended production runs.

Which dimensions are critical when selecting a compatible holder?
Key dimensions include the insert shape and size (09), plate thickness (3.18 mm), relief angle (11°) and the hole and countersink geometry; these determine compatibility and clamping stability.
