TCMT 16T304 T9225 Tungaloy turning insert — ISO triangular insert for medium-to-heavy steel turning (60°)

The TCMT16T304 T9225 is an ISO-standard triangular turning insert designed for robust external and internal turning, offering a balance of wear resistance and toughness for variably interrupted cuts.

• CVD-coated cemented carbide grade T9225
• ISO 60° triangular format TCMT 16T304
• Single-sided chipbreaker for controlled chips
• 0.4 mm corner radius for repeatable profiles

Consistent performance where interruptions occur

The CVD-coated, cemented carbide composition of this grade (T9225) delivers a compromise between wear resistance and toughness that is particularly valuable in medium-to-heavy steel turning where cutting conditions can vary or cuts may be slightly interrupted. Chemical vapour deposition (CVD) applies a hard, wear-resistant layer to the carbide substrate; this improves flank and crater wear behaviour while preserving the substrate’s ability to absorb shock. The result is fewer unexpected tool failures and a more predictable component finish, which contributes to steadier production flows and reduced rework.

Predictable fit and accurate geometry for repeatable set-ups

Built to ISO shape and size, the triangular 60° geometry (TCMT) and dimensional tolerances ensure consistent seating in compatible holders. The insert’s 7° clearance angle and 0.4 mm corner radius produce predictable contact conditions at the cutting edge, aiding surface quality and dimensional control on turned parts. The 3.97 mm plate thickness and the specified hole style (cylindrical hole with one-sided countersink 40°–60°) support secure clamping and ease of replacement in the usual external holders or boring bars. Such standardisation reduces set-up time and minimises variability between tool changes.

Effective chip control and operational economy

Equipped with a single-sided chipbreaker, this triangular insert promotes reliable chip formation and evacuation during turning, which lowers the risk of chip entanglement and heat concentration at the cutting edge. Stable chip control extends insert life and reduces machine downtime, increasing overall process efficiency. The insert’s robust universal grade is suitable when changing engagement or slight interruptions demand additional toughness; combined with proper holder selection and cutting parameters, it supports longer tool life and more consistent component quality. A typical system comprises the ISO insert, a matching external holder or boring bar, a backing plate or clamp set and replacement screws for quick field exchange.

FAQ

What machining tasks is this insert best suited for?
This insert is intended for turning operations, especially medium-to-heavy steel machining where toughness and wear resistance are required; the T9225 grade balances both properties.

How does the T9225 grade affect tool life?
The CVD-coated T9225 grade increases resistance to abrasive wear while its carbide core provides toughness for interrupted cuts, which together contribute to longer, more predictable insert life.

What are the key geometry parameters to consider when selecting a holder?
Consider the ISO triangular shape, 60° angle, 0.4 mm corner radius, 7° clearance angle and the plate thickness; matching these ensures secure clamping and repeatable positioning of the insert.
