TPMT 16T304 T9225 triangular turning insert, CVD-coated carbide (Tungaloy)

TPMT16T304-TSF T9225 is a triangular ISO turning insert engineered for medium-to-heavy steel machining with ISO-compatible holders and a TSF chipbreaker.

• CVD-coated carbide T9225
• Universal grade for medium-heavy steel
• Triangle insert with 60° cutting angle
• 0.4 mm corner radius for versatile cuts

Faster cycles through a robust, universal grade

The insert uses a CVD-coated carbide substrate in the T9225 grade, chosen for its balance of toughness and wear resistance in interrupted or variable cuts. This combination supports higher cutting parameters and longer tool life under fluctuating engagement, translating into fewer tool changes and improved machine uptime. The result is a measurable uplift in productivity for workshops running mixed batch sizes, where consistency and predictable edge performance are essential.

Clear guidance on holder compatibility and mounting

Compatibility depends on geometry: form, relief angle, tolerance class, fastening, size and thickness determine correct pairing with holders. The triangle shape and with hole design — a cylindrical hole with a one-sided countersink at 40°–60° — ensure secure clamping when used with appropriate ISO external holders or boring bars. Specifying holders that match the 11° relief and 3.97 mm plate thickness prevents misalignment and secures stable cutting conditions, reducing vibration and improving surface finish.

Predictable edge life in demanding steel turning

For medium-to-heavy steel operations, the TSF chipbreaker combined with the 0.4 mm corner radius provides a compromise between chip control and edge strength. This geometry reduces tendency to notch and maintains positive cutting action on variable shoulders or interrupted cuts. When the TPMT16T304-TSF T9225 insert is used with stable setups, the outcome is consistent dimensional accuracy and fewer reworks, supporting cost-efficiency in serial production and repair tasks.

Simple specification for process planning and inventory

Process planners benefit from the ISO designation and measurable parameters: 16 mm size, 3.97 mm thickness, 60° cutting angle and defined hole style. These clear specifications simplify tool list creation, stock keeping and rapid replacement. Selecting the correct grade and chipbreaker for the material and operation avoids over‑engineering and supports an efficient, repeatable machining routine with lower overall tooling consumption.

FAQ

What machining tasks suit this insert best?
The insert is intended for external and internal turning operations, especially mid- to heavy-duty steel machining where variable engagement or slight interruptions require a tougher grade such as T9225.

Is the insert compatible with standard ISO holders?
Compatibility is determined by form, relief angle, tolerance and thickness; the TPMT geometry and the specified 11° relief mean the insert fits ISO-compliant external holders designed for triangular inserts, given matching clamping and support.

How does the TSF chipbreaker affect performance?
The TSF chipbreaker promotes controlled chip formation in steel turning, improving evacuation and reducing built-up edge risk, which enhances surface finish and tool life in the specified grade.

What material is the insert made from?
The cutting body is made of carbide and finished with a CVD coating, delivering balanced wear resistance and toughness suited to the grade T9225.

Which dimensions should be specified when ordering replacements?
Key dimensions are ISO designation TPMT16T304-TSF, size 16 mm, thickness 3.97 mm, corner radius 0.4 mm and the hole/countersink style; quoting the article number 6781468 or SKU 6781468-Tungaloy ensures exact replacement.
