DCMT 070204 T9225 turning indexable insert by Tungaloy — CVD-coated carbide, rhombic DCMT 07

The DCMT070204 T9225 is an ISO‑standard rhombic turning indexable insert designed for medium to heavy Stahl turning applications, offering a balance of toughness and wear resistance for variable engagement conditions.

• CVD-coated carbide for enhanced durability
• Robust universal grade T9225 for Stahl turning
• ISO rhombic DCMT 07 form, 55° included angle
• Cylindrical hole with 40°–60° countersink

Consistent performance where interrupted cuts occur

The CVD‑coated T9225 grade is formulated for robust universal use, providing increased toughness where cuts are intermittent or engagement varies. The combination of a coated carbide substrate and the T9225 chemistry reduces flank wear under fluctuating loads and helps maintain cutting-edge integrity, which in turn lowers the rate of insert changes and contributes to steadier production yields. This makes the insert particularly suitable for demanding workshop and production turning tasks on Stahl.

ISO compatibility for seamless toolholder integration

Delivered in an ISO‑compliant rhombic DCMT 07 format, the insert integrates with standard external holders and boring bars when matched by form, clearance, tolerance class, fastening and thickness. The cylindrical hole plus a 40°–60° countersink ensures secure clamping and repeatable seating. Using an ISO‑matched holder and the correct clamping kit preserves positional accuracy and minimises runout, enabling consistent component quality across batch runs.

Geometry tuned for surface finish and stability

The rhombic shape with a 55° included angle and 0.4 mm corner radius balances edge strength and accessible cutting geometry. A 7° clearance angle reduces rubbing and improves surface quality while the single-sided chipbreaker supports controlled chip formation on typical turning feeds. These geometric choices reduce vibration sensitivity and help achieve reliable finishes with fewer rework cycles.

Practical benefits for production and process reliability

Selecting an insert with the T9225 grade and the DCMT form supports a wide material range and simplifies tooling inventory by offering a versatile option for many turning tasks. The insert’s design encourages longer tool life and stable chip control, which together reduce downtime and tool change frequency. For process planning, pair the insert with a suitable chipbreaker and holder geometry to match feed, depth of cut and component tolerances for optimal productivity and cost efficiency.

FAQ

Which materials is this insert suitable for?
The DCMT070204 T9225 insert is intended primarily for medium to heavy Stahl machining; the CVD coating and universal T9225 grade also allow a broad range of common engineering materials to be machined with stable chip control.

What does the 0.4 mm corner radius mean for finish and strength?
A 0.4 mm corner radius offers a compromise between a fine surface finish and edge robustness; it helps absorb shock during interrupted cuts while still enabling acceptable surface quality on turned parts with standard feeds.

How does the hole and countersink affect clamping?
The cylindrical hole with a 40°–60° countersink ensures secure and repeatable seating in compatible ISO toolholders, improving positional accuracy and reducing the risk of insert movement under load.

Is this insert suitable for interrupted cuts or unstable engagement?
Yes, the T9225 robust universal grade is designed for situations with varying engagement or light interruptions, providing additional toughness compared with highly wear‑resistant but brittle grades.

What should be matched when selecting a holder for this insert?
Match the holder by ISO form (DCMT), clearance angle (7°), tolerance class, fastening style and insert thickness to ensure proper fit and functional clamping within the tool system.
