CPMT 09T304 T515 — CPMT indexable insert for turning by Tungaloy — CVD-coated carbide, 0.4 mm corner radius

CPMT 09T304 T515 is an ISO-format rhombic indexable insert for turning, designed for economical machining of cast iron and applications requiring controlled chip formation and repeatable edge life

• ISO-format rhombic insert size 09
• CVD-coated carbide grade T515
• Single-sided chipbreaker for cast iron
• 0.4 mm corner radius, 11° clearance

Consistent, economical results for cast-iron turning

The CVD-coated T515 grade delivers a balance of wear resistance and cost-effectiveness for the machining of cast iron. The coating improves surface hardness and reduces flank wear, which translates to longer usable edge life under stable cutting conditions. With the single-sided chipbreaker configured for reliable chip control, the insert supports steady material removal and predictable tool-change intervals. This leads to a measurable improvement in process uptime and makes the component suitable for batch production or continuous turning tasks where economy and repeatability matter.

Precision geometry that supports repeatable machining

The rhombic geometry (size 09) combined with a 0.4 mm corner radius and an 11° clearance angle ensures a defined cutting engagement and consistent tool-workpiece contact. The insert’s 3.97 mm thickness and the 80° insert angle provide mechanical stability in the seat, reducing vibration when paired with a correctly matched holder. The central hole with a cylindrical bore and a one-sided countersink (40°–60°) enables secure clamping in standard indexable holders; compatibility depends on matching form, clearance angle, tolerance class, fastening method, size and thickness, so selection of the appropriate external holder is essential for achieving the rated performance.

Practical handling and process guidance for mills and lathes

Installation and rotation of indexable inserts like this one are straightforward when the correct insert seat is used. The ISO standard format simplifies stocking and replacement logistics across tool rooms. For interrupted cuts or less rigid set-ups, choose the chipbreaker and cutting data according to workpiece stability and desired cutting speed; the grade is optimised for cast iron but selection should reflect the actual operating conditions. The construction reduces the frequency of regrinding or disposal and supports predictable production planning, while the standardised form makes integration into existing tool systems uncomplicated.

FAQ

Which materials is this insert intended for?
This insert is specified for the economical machining of cast iron; the CPMT09T304 T515 grade is optimised for that material and cutting behaviour.

What are the key geometric features of the insert?
The insert has a rhombic form (size 09), a 0.4 mm corner radius, 3.97 mm thickness, and an 11° clearance angle; the CPMT09T304 includes a central hole with a cylindrical bore and one-sided countersink.

What coating and grade does the insert use?
The cutting edge is a CVD-coated carbide in grade T515, designed for wear resistance and cost-effective performance on cast iron.

How should compatibility with holders be checked?
Compatibility requires matching the insert’s form, clearance angle, tolerance class, fastening method, size and thickness; verify these parameters against the chosen external holder before mounting the CPMT09T304 T515.

Is this insert suitable for interrupted cuts?
Interrupted cuts demand selection based on stability and cutting conditions; the chipbreaker and grade should be chosen accordingly, with the T515 grade suitable for many cast-iron turning tasks depending on machine and setup.
