TNMG 110404 T9225 turning insert — 0.4 mm radius, 60° triangle, Tungaloy

The TNMG110404 T9225 is an ISO‑standard triangular turning insert for external and internal turning, engineered as a robust universal grade for medium to heavy steel machining.

• ISO‑standard triangular geometry
• CVD‑coated carbide T9225
• 0.4 mm nose radius for fine finishing
• Double‑sided chipbreaker, with centre hole

Higher throughput through a balanced grade and geometry

A CVD‑coated T9225 carbide grade provides a favourable balance between wear resistance and toughness, which translates into fewer tool changes and higher machine uptime. The 60° included angle of the triangular insert brings inherent stiffness at the cutting zone, supporting stable cuts when machining steels under varying engagement conditions. With a 0.4 mm nose radius the insert allows for improved surface finish without sacrificing process reliability, while the coating helps to resist built‑up edge and abrasive wear. This combination is designed to boost productivity in batch and single‑piece production alike.

Secure clamping and compatibility for predictable results

Clamping uses a central cylindrical hole together with the appropriate clamp or screw; the insert’s compatibility to a holder depends on form, 0° relief angle, tolerance class, fastening, size and thickness. The double‑sided chipbreaker gives two usable sides per face, simplifying indexing and stock management. As an ISO‑standard component, the geometry and hole style make it straightforward to find matching external holders or boring bars, reducing setup time and ensuring repeatable seating and alignment.

Practical handling, system set‑up and selection guidance

The insert has a plate thickness of 4.76 mm and a plate size of 11 mm, delivered in a triangular form with a cylindrical centre hole and a double‑sided chipbreaker. Typical system composition comprises the ISO insert, a suitable external holder or boring bar, a backing shim or clamp set and spare screws. For interrupted cuts or varying engagement lengths the robust universal grade is preferable; select the chipbreaker and grade in line with workpiece stability and cutting mode to obtain optimal tool life and surface quality.

FAQ

Which materials are best machined with this grade?
The TNMG110404 T9225 insert is intended as a robust universal grade for medium to heavy steel machining; the CVD‑coating and carbide substrate help manage heat and wear during sustained turning operations.

How many cutting edges does the insert offer before re‑indexing?
A triangular, double‑sided insert like this typically provides six usable cutting edges (three corners, two usable faces each), enabling economical indexing and extended service life for the insert.

How is the insert fixed to the toolholder?
Fixing is achieved via the cylindrical centre hole and the corresponding clamp or screw in the holder; proper match of form, tolerance class, size and thickness is essential for secure clamping and repeatable performance.

Can this insert be used for internal turning and boring operations?
Yes — the insert is suitable for both external and internal turning when paired with the correct ISO‑compatible boring bar or internal holder and the appropriate clamping accessories.

What dimensional checks are needed to ensure holder compatibility?
Verify the included angle (60°), plate size (11 mm), plate thickness (4.76 mm), nose radius (0.4 mm) and the presence and style of the centre hole; matching these dimensions with the holder specification ensures correct seating and clamping.
