TNMU 120708 T3225 TNMU for milling by Tungaloy — 60° triangular insert, 0.8 mm radius

TNMU120708 T3225 Tungaloy indexable insert for modular milling systems, designed for shoulder, slot, face and contour milling depending on head geometry

• Triangular insert, 60° geometry for robust milling
• Tungaloy grade T3225 for wear resistance and toughness
• Double-sided chipbreaker with cylindrical hole and countersink
• Compatible with TungMeister modular milling heads

Modular system design that raises productivity

The TungMeister modular concept pairs interchangeable heads with reusable shafts, allowing shops to adapt tooling to diverse tasks while reducing component waste and inventory complexity. A modular approach shortens set-up times and lowers lifetime costs by limiting full-head replacements; instead, only the cutting head or insert needs renewing. This results in more predictable machine uptime and a straightforward route to higher throughput when shifting between shoulder, slot or contour milling jobs.

Proven cutting performance from Tungaloy grade T3225

The insert is manufactured in Tungaloy carbide grade T3225, which balances wear resistance and toughness to maintain edge stability under mixed cutting conditions. That combination reduces flank wear and supports consistent surface finish over longer tool life, especially on interrupted cuts typical of slotting. In industrial production environments the material choice translates directly into fewer indexings and lower per-part tooling expenditure while keeping process windows stable.

Geometry and chip control for reliable results

A 60° triangular form with a 0.8 mm corner radius delivers a compromise between strength and profile fidelity: the larger included angle enhances edge support for heavier cuts, while the radius reduces stress concentration at the corner. The insert is double-sided with a dedicated chipbreaker and a cylindrical centre hole with double-sided countersink (40°–60°) to ensure secure clamping and controlled chip formation. These features make the insert suitable for a broad set of milling strategies and simplify fixture requirements.

Practical compatibility and application range

The indexable insert is specified for milling and is supplied to suit the TungMeister modular heads, offering flexible deployment across shoulder, groove, face and contour tasks depending on head geometry. The part is made of carbide and is intended to be used in systems where head interchangeability and quick insert changes are priorities. For shops uncertain about optimal head geometry or cutting data, Metav Werkzeuge provides application guidance and can supply matching shafts and mounting accessories.

FAQ

What materials is this insert suitable for?
The TNMU120708 T3225 insert is a carbide milling insert designed for general milling tasks; the T3225 grade provides a balance of wear resistance and toughness suitable for a wide range of workpiece materials encountered in production milling.

How does the 60° geometry affect milling performance?
A 60° triangular geometry increases edge support and rigidity, helping the insert withstand heavier cuts and providing stable performance in face and contour milling operations with improved tool life.

Is the insert reversible or single-use per edge?
This is a double-sided indexable insert, permitting multiple edge uses. The double-sided chipbreaker and robust geometry support repeated indexings while maintaining cutting stability.

Can the insert be clamped in existing TungMeister heads?
The TNMU120708 is intended for the TungMeister modular milling system and is compatible with the series’ interchangeable heads and reusable shafts; verify head compatibility with the system drawing or consult Metav Werkzeuge for confirmation.

What does the hole and countersink specification mean for clamping?
The central cylindrical hole with a double-sided countersink (40°–60°) ensures reliable seating and positive clamping in the insert pocket, which contributes to consistent cutting performance and secure assembly.
