TCMT 16T304 T9225 turning insert — CVD-coated carbide, 7° relief (Tungaloy)

The TCMT 16T304 T9225 is an ISO-standard triangular turning insert engineered for medium-to-heavy steel turning, offering a 0.4 mm corner radius and a 7° relief angle for secure cutting performance.

• CVD-coated carbide grade T9225
• ISO triangular insert, 16 mm size
• 0.4 mm corner radius, 7° relief
• Cylindrical hole with 40°–60° countersink

Consistent performance where toughness matters

The combination of a CVD-coated surface and a carbide substrate provides an optimised balance between hardness and fracture resistance, making this triangular insert especially suited to interrupted cuts and varying engagement conditions. The T9225 grade is formulated as a robust universal grade for medium-to-heavy steel turning, which means fewer unexpected edge failures and steadier productivity in demanding operations. Because the insert conforms to ISO geometry standards, matching the correct holder becomes a matter of checking form, clearance angle and tolerance class rather than guessing, which reduces setup time and simplifies tool management.

Longer edge life and controlled chip formation for higher uptime

A reliable grade and an integrated single-sided chipbreaker enable stable chip control and more predictable wear patterns. The CVD coating reduces abrasive wear and helps maintain the cutting edge under heat, while the substrate toughness resists chipping when conditions are variable. This results in less frequent insert changes and fewer interruptions to production. The measurable improvements in tool life translate directly into production benefits: reduced downtime, lower tooling consumption per component and improved process stability when machining steels of varying machinability.

Practical mounting and dimensional clarity for easy integration

Designed as a triangular insert with a 16 mm size and a plate thickness of 3.97 mm, the geometry includes a 0.4 mm corner radius and a 60° included angle, which together influence both strength and surface finish. The insert features a cylindrical hole with a single-side countersink (40°–60°), permitting secure clamping with standard ISO-compatible screws and shims. The 7° relief angle reduces rubbing on the flank face and supports better surface finish at moderate feed rates. When selecting an external holder or boring bar, compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness—this system approach ensures the insert can be integrated without compromise.

Typical applications and material matching

Intended primarily for turning operations, the insert performs well on steel and alloyed steels where a tougher grade is required to handle fluctuating cutting conditions or slightly interrupted cuts. The T9225 grade provides a pragmatic middle ground between wear resistance and toughness: suitable for semi-finish and roughing passes where robustness is more important than minimal cutting forces. For customers seeking a balance of performance and versatility, this insert offers a straightforward choice that reduces the need for numerous specialised grades while maintaining consistent outcomes across batches.

FAQ

What materials is this insert best suited for?
The TCMT 16T304 T9225 insert (SKU 6780996-Tungaloy) is optimised for medium-to-heavy steel turning; its CVD-coated carbide construction provides the toughness and wear resistance needed for variable engagement and interrupted cuts.

What is the corner radius and how does it affect machining?
The insert has a 0.4 mm corner radius, which increases edge strength and supports stable roughing and semi-finishing passes; the modest radius balances surface finish and robustness during heavier cuts.

How is the insert secured in the holder?
The triangular insert uses a cylindrical hole with a single-side countersink (40°–60°) for secure clamping; compatibility with a holder is determined by form, relief angle, tolerance class, fastening method, size and thickness.

Can this insert be used for fine finishing operations?
While the grade is designed for medium-to-heavy turning, light finishing passes are possible if cutting parameters and feed rates are adapted; for ultra-fine finishes, a smaller radius or a purpose-designed finishing grade may be preferable.

Which holders are compatible with this ISO insert?
Any ISO-compatible external holder or boring bar that matches the TCMT geometry—size 16, 7° relief, and triangular form—will be compatible; ensure the clamp and shim accommodate the cylindrical hole with countersink.
