TPMT 16T304 T9225 triangular turning insert — ISO turning insert by Tungaloy

TPMT16T304-PM T9225 is a triangular, ISO‑standard turning insert developed for medium to heavy steel machining where intermittent cuts and varying engagement demand extra toughness.

• CVD-coated carbide T9225 grade
• Triangular ISO insert, 16 mm size
• 0.4 mm corner radius for versatile cuts
• 11° clearance, cylindrical hole with countersink

Consistent metal removal under variable conditions

The CVD‑coated, carbide construction provides a balance of hardness and toughness that supports productive machining in mixed shop environments. The T9225 grade is engineered as a robust universal option for medium to heavy steel machining, offering stable chip formation and improved resistance to micro‑chipping when cuts are interrupted. The insert’s chipbreaker PM is matched to the grade, which helps maintain consistent chip control during turning and reduces cycle‑time losses caused by poor evacuation. For process planners, this translates into predictable material removal rates and fewer unplanned tool changes.

Precision geometry for reliable toolholder compatibility

Shaped to ISO standards, the triangular form and the 16 mm size ensure compatibility with a wide range of external toolholders and boring bars when the seat form, thickness and fixing system match. The 0.4 mm corner radius supports a compromise between edge strength and surface finish, permitting moderate feed rates without sacrificing edge life. The insert’s 11° clearance angle reduces rubbing at the flank face and aids in maintaining dimensional accuracy, while the central cylindrical hole with a one‑sided countersink (40°–60°) assures secure clamping and consistent repeatability in indexable setups.

Long tool life through engineered coating and material selection

A CVD coating on the carbide substrate provides wear resistance on the rake face and thermal stability at elevated cutting temperatures typical of steel turning. The substrate material—sintered carbide—combines substrate toughness with a hard contact surface to withstand the abrasion and heat in continuous and interrupted cuts. This engineered pairing reduces flank wear and extends usable edge life, supporting longer tool cycles and fewer interventions for index changes. For manufacturers seeking steady output and lower tooling consumption, the result is improved process economy and less downtime.

FAQ

What materials is this insert suitable for?
The TPMT16T304‑PM T9225 is specified for medium to heavy steel machining, providing toughness for intermittent cuts and variability in engagement.

How does the PM chipbreaker affect performance?
The PM chipbreaker promotes controlled chip formation in turning operations, improving evacuation and reducing the risk of chip interference with the tool or workpiece.

What clamping and holder features are required for correct mounting?
Correct compatibility depends on the holder seat form, clearance angle, tolerance class, fixing method, insert size and thickness; the insert’s cylindrical hole with countersink ensures reliable clamping when the holder is ISO‑matched.

Can this insert be used for finishing as well as roughing?
The T9225 grade is a versatile universal option; while optimised for medium to heavy cuts, appropriate feeds and speeds can achieve satisfactory finishing results depending on component tolerances.

What is the benefit of the 0.4 mm corner radius?
A 0.4 mm corner radius increases edge strength for interrupted cuts while still allowing moderate feeds that keep surface finish within acceptable ranges for many turned components.
