TPMT16T308-23 T9225 — Triangle ISO turning insert for medium to heavy steel by Tungaloy

The TPMT16T308-23 T9225 is a triangle ISO turning insert designed for turning applications, offering a robust CVD-coated carbide grade for variable engagement conditions and interrupted cuts.

• CVD-coated carbide grade T9225
• Triangle 60° geometry for versatile turning
• 0.8 mm corner radius for consistent strength
• Cylindrical hole with 40°–60° countersink

Durable grade for demanding steel turning with stable chip control

The insert combines a CVD-coated surface with a tough carbide substrate to balance wear resistance and fracture toughness, making it suitable for medium to heavy steel machining where cutting conditions vary. The specified T9225 grade is developed for reliable performance during interrupted cuts or when the engagement depth changes, which reduces the risk of edge chipping and extends tool life. This technical pairing delivers efficient material removal rates while maintaining surface quality, supporting continuous production and fewer tool changes.

Precision geometry for secure clamping and predictable results

A triangle shape with a 60° included angle offers multiple effective cutting edges and straightforward indexing, while the 0.8 mm corner radius provides edge strength for robustness in heavier cuts. The 11° clearance angle helps avoid rubbing and reduces built-up edge formation, improving dimensional stability on the workpiece. The insert’s cylindrical hole with a 40°–60° one-sided countersink ensures positive and repeatable clamping in compatible holders, which contributes to consistent cutting forces and improved workpiece finish.

Compatibility guidance and practical selection advice

These ISO-format turning inserts are compatible with holders and boring bars when the form, clearance angle, tolerance class, fastening, size and thickness match; the system typically comprises the insert, a suitable external holder or boring bar, a seat/clip set and replacement fixing screws. Selecting the chip breaker 23 and the T9225 grade aligns chip form and toughness with the demands of intermittent cuts and variable stability. For workshop planning, choosing the correct holder geometry and clamping sets reduces vibration and maximises tool life, so evaluate fixture tolerance and assembly sequence when integrating this insert.

FAQ

What materials is this insert suitable for?
The TPMT16T308-23 T9225 insert is specified for medium to heavy steel machining and is designed to handle variable engagement and interrupted cuts.

How does the chip breaker affect performance?
Chip breaker 23 on this Tungaloy turning insert shapes chips for controlled evacuation, improving process stability and reducing the risk of built-up edge during longer cuts.

What does the hole and countersink specification mean for clamping?
The cylindrical hole with a one-sided 40°–60° countersink enables positive, repeatable clamping in compatible holders, supporting consistent cutting forces with the TPMT16T308-23 T9225.

Is this insert compatible with standard ISO holders?
ISO compatibility depends on matching form, clearance angle, tolerance class, fastening method, size and thickness; the series is intended for ISO-format holders when those parameters align.

How many cutting edges are available before re-indexing?
The triangle geometry provides multiple indexed cutting edges; the exact number of usable edges before replacement depends on application specifics and wear rates for the TPMT16T308-23 T9225.
