DNMM150612-57 T9225 ISO turning insert for turning — CVD-coated carbide, 1.2 mm radius (Tungaloy)

DNMM150612-57 T9225 is an ISO-standard turning insert engineered for medium to heavy steel turning, delivering robust edge life and consistent chip control in interrupted or variable cutting conditions

• CVD-coated carbide grade T9225
• Suitable for medium to heavy steel turning
• ISO rhombic insert with 55° cutting angle
• 1.2 mm nose radius, cylindrical hole

Stable cutting performance for demanding steel work

The CVD-coated carbide composition and the T9225 grade provide a balance of toughness and wear resistance that suits interrupted cuts and fluctuating engagement. The combination of a 1.2 mm nose radius and a 55° insert geometry helps maintain a predictable contact area, reducing vibration and improving surface finish during external and internal turning. By favouring a universal grade, the insert supports a broad range of steel types while prioritising process stability and longer tool life.

Compatibility and secure clamping for faster setup

Manufactured to ISO dimensions, the rhombic DNMM geometry and the cylindrical hole simplify selection and clamping in compatible holders. Compatibility is determined by the insert form, relief angle, tolerance class, fixing method, size and thickness; the standardised shape reduces search time for suitable toolholders and spare parts. The 6.35 mm plate thickness and clear dimensional standards enable straightforward replacement and consistent positioning, which shortens machine downtime and supports repeatable set-ups.

Clear benefits for productivity and process reliability

Choosing a universal, robust grade such as T9225 helps improve overall throughput by extending tool life and stabilising chip formation under heavy or variant cutting loads. The insert’s design, including the 55° cutting angle and CVD coating, supports reliable surface quality with fewer tool changes. For production environments where predictable results and reduced process variability matter, this geometry-grade combination reduces rework and contributes to predictable machining cycles.

FAQ

What materials is this insert suitable for?
The DNMM150612-57 T9225 insert is intended primarily for steel machining, serving medium to heavy turning operations where toughness and wear resistance are required.

How does the T9225 grade differ from other grades?
The T9225 grade combines CVD coating with a resilient carbide substrate to offer broad application range, improved chip control and enhanced resistance to fracture during interrupted cuts.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, relief angle, tolerance class, fixing method, size and thickness; the ISO rhombic DNMM format fits standard DNMM holders when those parameters match.

What is the purpose of the cylindrical hole in the insert?
The cylindrical hole enables secure clamping and repeatable positioning in clamping sets and seatings designed for ISO rhombic inserts, improving assembly speed and stability.

Can this insert be used for finishing as well as roughing?
Yes; with appropriate feed and speed adjustments the insert’s 1.2 mm nose radius and coating allow for good surface finish in finishing passes while still being robust enough for roughing.
