DNMG150612 T9225 Turning insert — rhomboid ISO turning insert, 55° (Tungaloy)

A DNMG150612 T9225 indexable insert engineered for external and internal turning, offering a tough CVD-coated cemented carbide grade tailored to variable engagement conditions

• CVD-coated cemented carbide grade T9225
• 55° rhomboid geometry with cylindrical hole
• 1.2 mm corner radius for stable cutting
• 6.35 mm thickness, double-sided chipbreaker

Predictable performance for medium-to-heavy steel turning

The insert’s CVD-coated cemented carbide composition provides a balance of wear resistance and toughness suitable for interrupted cuts and fluctuating engagement. The T9225 grade is formulated to deliver consistent tool life under medium-to-heavy steel machining, reducing unplanned tool changes. The 55° rhomboid geometry concentrates cutting forces on a supportive rake face, while the 0° relief angle supplies secure edge engagement; together these characteristics promote steady chip formation and reliable dimensional control for repetitive production runs.

Streamlined compatibility and efficient indexable replacement

Manufactured to ISO norms, the insert fits holders according to form, relief, tolerance class, fastening and thickness. The cylindrical hole ensures positive locating and repeatable clamping, while the 6.35 mm thickness and double-sided chipbreaker enable two usable edges per side, lowering tooling costs through effective indexing. Clear specification of holder type and clamp arrangement avoids mismatch at setup, shortening downtimes and simplifying inventory by standardising on ISO-compliant components.

Improved process economy and machining stability

The 1.2 mm corner radius combines edge strength with acceptable surface finish for a broad range of turning tasks; larger radii favour stability on heavy cuts, smaller radii favour finer finishes. With the T9225 grade, wear progression is gradual, which supports predictable maintenance intervals and reduced scrap. This results in measurable process benefits such as higher uptime and fewer reworks—advantages that translate into a better cost-per-part ratio across production batches.

Typical uses and practical handling guidance

Designed for both external and internal turning, this rhomboid insert performs well when matched to the appropriate chipbreaker and cutting parameters. Select the chipbreaker and grade according to workpiece material and machining stability; consider a more positive chip control for light interrupted cuts and a tougher approach for heavy engagement. When fitting the insert, ensure correct torque on the clamping screw and confirm seat cleanliness; incorrect clamping is a common source of premature edge failure.

FAQ

What materials is this insert intended for?
The DNMG150612 T9225 insert is a robust universal grade intended primarily for medium-to-heavy steel turning; the T9225 coating and substrate combination supports variable engagement conditions.

How is the insert indexed and secured?
The insert features a cylindrical hole for positive locating and is secured by a compatible clamp or screw in an ISO-standard holder; the 6.35 mm thickness and seat geometry ensure repeatable clamping.

Can this insert be used for internal as well as external turning?
Yes — the rhomboid geometry and chipbreaker make the insert suitable for both external and internal turning operations when paired with an appropriate holder and parameters.

What benefits does the T9225 grade offer in production?
T9225 provides a balance of wear resistance and toughness, offering predictable tool life, stable chip formation and efficiency in medium-to-heavy steel machining.

Which corner radius is fitted and what does it affect?
The insert has a 1.2 mm corner radius; this radius improves edge strength and stability, making it suitable for heavier cuts while maintaining acceptable surface finish.
