DPMT 11T304 T9225 – Indexable turning insert, CVD‑coated carbide by Tungaloy

The DPMT11T304 T9225 is an ISO‑standard rhombic indexable insert for external and internal turning, engineered for robust performance in medium to heavy steel machining applications

• Robust CVD-coated carbide grade T9225
• ISO rhombic insert DPMT 11T304
• 11° clearance angle for stable cutting
• Cylindrical hole with single-sided countersink

Stable performance under varying cutting conditions

The combination of a CVD‑coated protective layer and a carbide substrate in grade T9225 is aimed at delivering stable chip formation and extended service intervals in mixed cutting scenarios. This turning grade is formulated to offer increased toughness where interrupted cuts or variable engagement occur, which translates into fewer tool changes and improved throughput. The coating is applied to enhance wear resistance, while the substrate maintains edge integrity; together they support longer stand‑time and consistent component quality.

Defined geometry and mounting for reliable process security

Adherence to the ISO DPMT form ensures reproducible seating and repeatable results when combined with a compatible holder or boring bar. The insert is rhombic with a nominal size of 11 and a thickness of 3.97 mm, featuring an 11° clearance angle that helps reduce rubbing and vibration. The central cylindrical hole with a single‑sided countersink (40°–60°) secures clamping and alignment; correct selection of tolerance class and fastening method will maintain process stability and surface finish. The one‑sided chipbreaker design supports chip control adapted to the workpiece and operation.

Practical gains in workshop productivity and surface quality

With a corner radius of 0.4 mm and an effective approach angle of 55°, the insert balances cutting-edge strength and surface finish requirements for both roughing and light finishing passes. The single‑side chipbreaker is suited to higher engagement angles and intermittent cuts, reducing the risk of edge chipping. As a result, cycle times can be optimised without sacrificing reproducibility of component dimensions. Technical advisors can provide tailored cutting parameters and grade selection to match the required material removal rates and finish demands.

FAQ

Which materials is the insert best suited for?
The Tungaloy DPMT11T304 T9225 is designed as a robust universal grade for medium to heavy steel machining and performs well where changing engagement or interrupted cuts require additional toughness.

Will this insert fit existing ISO holders?
Compatibility depends on matching the DPMT form, clearance angle, tolerance class, fastening and thickness; the DPMT11T304 form is ISO‑standard and will fit holders specified for that insert geometry.

What does the T9225 grade offer compared with other grades?
Grade T9225 is a CVD‑coated carbide developed for a balance of wear resistance and toughness, offering stable chip formation and reliable edge life under variable cutting conditions.

Is the insert suitable for interrupted cuts or unstable chip loads?
Yes, the combination of T9225 toughness and a one‑sided chipbreaker is intended to cope with interrupted cuts and moderate instability, reducing the risk of premature edge failure.

How does the 0.4 mm corner radius affect the machining result?
A 0.4 mm radius provides improved edge strength compared with very small radii while still allowing acceptable surface finish; it is a compromise between roughing robustness and the ability to achieve fine finishes.
