CPMT 09T308 T5115 Tungaloy turning insert — ISO rhombic insert for external and internal turning

CPMT 09T308 T5115 is an ISO-form indexable insert designed for turning applications, offering a universal grade optimised for cast iron and stable edge performance

• ISO rhombic insert, size 09
• CVD-coated carbide grade T5115
• 0.8 mm corner radius for versatility
• Cylindrical hole + 40°–60° countersink

Consistent cutting performance tailored to cast iron

The combination of a CVD-coated surface and a wear-resistant carbide substrate provides a balanced mix of edge stability and longevity, making this insert particularly effective for cast iron turning. The single-sided chipbreaker controls chip formation and helps maintain stable cutting forces, which in turn reduces vibration and supports consistent dimensional accuracy. With the rhombic geometry and a standard insert angle, these characteristics result in improved process reliability and fewer interruptions during batch production.

Interchangeability and secure clamping for predictable set-up

Built to ISO norms, the insert enables straightforward interchangeability across compliant holders; compatibility is governed by insert form, the 11° relief, tolerance class, fastening method, size and thickness. The central cylindrical hole with a single-sided countersink (40°–60°) ensures secure mounting and accurate seating, while the 3.97 mm thickness contributes to mechanical rigidity under cutting load. A 0.8 mm corner radius moderates edge strength and surface finish, allowing selection of feeds that balance productivity and final component quality.

Productivity gains and lower machining risk

Using a universal grade designed for cast iron reduces the need for frequent insert changes and trial-and-error set-ups, delivering steady cycle times and better first-pass yields. The optimised coating technology promotes controlled wear progression and consistent surface integrity, which leads to less rework and a more predictable tool-life profile. In practice, this means fewer unscheduled stops and a steadier flow in production environments where repeatability and uptime matter.

FAQ

What materials is this insert optimised for?
The CPMT 09T308 T5115 Tungaloy turning insert is optimised as a universal grade for cast iron, offering a balance of wear resistance and edge stability for reliable finishing and semi-finishing operations.

How does the insert secure to the holder?
Secure clamping is achieved via the central cylindrical hole combined with a single-sided countersink (40°–60°); the seating geometry and the 3.97 mm thickness ensure stable contact when used with ISO-compatible holders.

What influence does the 0.8 mm corner radius have on machining?
A 0.8 mm corner radius increases edge strength and supports higher feed rates while still producing a good surface finish, making it a versatile choice for a range of turning tasks on cast iron.

Is the grade suitable for both external and internal turning?
Yes, the rhombic form and the grade characteristics make the insert suitable for both external and internal turning where the toolholder geometry accommodates the ISO form.

How does the CVD coating improve performance?
The CVD coating on the carbide substrate enhances wear resistance and helps maintain edge integrity under varying cutting conditions, resulting in steadier tool life and improved process reliability.
