• For medium-to-heavy steel turning
• Rhombic ISO insert DPMT 070208
• 0.8 mm corner radius, cylindrical hole

Productivity through robust grade and coating

The combination of a CVD-coated surface and a carbide substrate provides a durable cutting edge that withstands interrupted cuts and fluctuating engagement. The T9225 grade is formulated for medium-to-heavy steel turning, delivering extended tool life and consistent surface finish where toughness is required. This results in fewer tool changes and higher machine uptime, which directly improves throughput and lowers per-part machining cost.

Secure fit and fast changeovers for stable machining

Designed as an ISO rhombic insert, the geometry and the cylindrical hole with one-sided countersink (40°–60°) ensure positive seating and repeatable clamping in compatible holders. The 11° clearance and 55° included angle support stable cutting forces and predictable chip flow when paired with an appropriate single-sided chipbreaker. The 0.8 mm corner radius balances edge strength with the ability to achieve the required contour accuracy on external and internal profiles.

Practical selection and application guidance

Choosing the correct chipbreaker and the T9225 grade enables productive machining across a broad range of steels, including alloyed and carbon steels under varying stability conditions. The insert thickness of 2.38 mm and size 07 make it compatible with standard external holders and boring bars for ISO DPMT-type geometries. For operations that demand robustness rather than the finest finish, this insert offers a reliable compromise between wear resistance and toughness, reducing process variation and rework.

FAQ

What materials is this insert suitable for?
The insert is optimised for steel machining; the T9225 grade offers toughness and wear resistance for medium-to-heavy steel turning applications.

Which holder type fits this ISO insert?
This rhombic DPMT 070208 insert fits holders and boring bars designed for DPMT-style ISO inserts, using the cylindrical hole and countersink for secure clamping.

How does the T9225 grade perform with interrupted cuts?
Tungaloy's T9225 grade is engineered for robust performance under variable engagement and light interruptions, providing stable edge life and reduced edge chipping.

What is the typical benefit of the 0.8 mm corner radius?
A 0.8 mm radius increases edge strength for heavier cuts while still enabling acceptable profile accuracy and surface quality in turning operations.
