TPMT130304-23 T9225 — ISO triangular turning insert, CVD-coated carbide (Tungaloy)

The TPMT130304-23 T9225 is an ISO triangular turning insert designed for external and internal turning, offering a universal, robust grade for medium to heavy steel machining.

• ISO triangular insert TPMT130304-23, T9225 grade
• CVD-coated carbide for robust performance
• 0.4 mm nose radius for profile stability
• 11° clearance angle for reliable cutting
• With hole and 40°–60° countersink for secure fixing

High-performance grade for variable cutting conditions

The T9225 designation denotes a CVD-coated carbide grade engineered for robustness during medium to heavy steel machining. Its chemistry and coating provide a balance of wear resistance and toughness, which is advantageous when cuts are slightly interrupted or when engagement varies. As a result, edge life is extended and process reliability increases, supporting higher productive throughput and fewer unplanned tool changes. The insert’s universal character makes it suitable across a range of turning tasks while maintaining consistent surface finish and dimensional control.

Secure clamping and geometry that supports repeatability

A triangular geometry with a 60° included angle and a 0.4 mm nose radius offers stable profile generation and predictable corner wear, which benefits operations that require repeatable part geometries. The insert is supplied with a cylindrical locating hole plus a single-sided countersink (40°–60°) for secure fixing and optimal seat contact; combined with an 11° clearance angle and a plate thickness of 3.18 mm, this creates a rigid assembly that minimises chatter and improves process stability. Compatibility with ISO holders is determined by form, clearance, tolerance class, fastening and size, ensuring straightforward selection of matching clamping systems.

Practical system advice and application efficiency

For efficient implementation, the insert functions as part of a system consisting of the indexable insert, a matching external holder or boring bar, a shim/clamping kit and replacement screws. Selecting the correct chipbreaker 23 and the T9225 grade for the specific steel grade and cutting conditions will reduce cycle times and tool consumption. The robust combination of geometry and coating supports longer tool life, lowers machine downtime and contributes to predictable production costs.

FAQ

What materials is this insert intended for?
The TPMT130304-23 T9225 is formulated primarily for medium to heavy steel machining and performs well under variable engagement where toughness is required.

How does the T9225 grade affect tool life?
The T9225 CVD-coated carbide grade combines wear resistance and toughness, which improves edge stability and extends life in interrupted cuts and heavy-duty turning tasks.

Which holders are compatible with this insert?
Compatibility is determined by the insert’s form, 11° clearance, tolerance class, fastening and thickness; matching ISO external holders or boring bars that accept TPMT triangular inserts are appropriate.

What is the purpose of the hole and countersink?
The cylindrical hole with a 40°–60° single-sided countersink ensures secure fixing and precise seat contact, which enhances repeatability and reduces the risk of insert movement during machining.

Can this insert be used for internal turning?
Yes, the TPMT130304-23 T9225 is suitable for both external and internal turning operations when paired with the correct boring bar and clamping system.
