DNMG 110408 T9225 — ISO turning insert, rhombic 55°, Tungaloy

A DNMG110408 T9225 insert designed for ISO-standard external and internal turning, offering a universal, tough grade for mixed and interrupted cuts in steel.

• CVD-coated carbide grade T9225
• Suitable for medium to heavy steel machining
• Double-sided chipbreaker, corner radius 0.8 mm
• Rhombic DNMG 11 mm, 55° cutting angle

Stable cutting performance for demanding steel operations

The CVD-coated T9225 carbide offers a blend of toughness and wear resistance, engineered for medium to heavy machining where cutting conditions change or interruptions occur. The robust grade reduces edge chipping and prolongs useful life under variable engagement, promoting consistent cycle times and fewer tool changes. By selecting an appropriate chipbreaker and matching the insert to the workpiece stability, the toolset supports efficient, economical production with predictable component quality.

Geometry and clamping designed for repeatability

Built to ISO geometry, the rhombic DNMG shape with a 55° cutting angle and a corner radius of 0.8 mm ensures reliable corner strength and favourable cutting forces. The insert includes a cylindrical hole and a 4.76 mm thickness, which together provide secure location and simple indexing in compatible holders. Compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness; when these match, clamping is secure and runout is minimised, improving surface finish and reducing vibration-related wear.

Efficient inventory and handling benefits

As a double-sided insert, each component offers two cutting edges, lowering per-edge cost and simplifying spare-part stocking. The universal nature of the grade and chipbreaker reduces the number of different inserts required for mixed steel work, aiding toolroom organisation and faster changeovers. Because the system comprises ISO inserts, a matched external holder or boring bar, underlay/clamp set and replacement screws, maintenance is straightforward and predictable, supporting uninterrupted machining cycles.

Practical application advice and material suitability

Specifically intended for turning, this insert is best applied to external and internal steel operations where a balance of toughness and wear resistance is required. The CVD-coated carbide substrate performs well under interrupted cuts and varying engagement typical of roughing and medium-depth finishing passes. Selection of cutting parameters and the correct chipbreaker is essential to harness the grade’s benefits; choosing the right combination will improve metal removal rates and tool life while maintaining component accuracy.

FAQ

What materials is this insert intended for?
The insert is intended primarily for steel turning; the T9225 CVD-coated carbide grade is engineered for medium to heavy steel machining and benefits interrupted or variable cutting conditions.

How does the insert locate in the holder?
Location requires a holder that matches the DNMG form: correct relief angle, tolerance class, fastening method, size and thickness ensure secure clamping and repeatable positioning for the insert.

Is this insert reversible or single-use per side?
This is a double-sided insert; each index provides additional cutting edges, reducing tooling costs and simplifying stock management.

Which chipbreaker should be selected for finishing?
The chipbreaker choice depends on workpiece material and cut stability; the available double-sided chipbreaker on this grade supports a range of finishing and roughing strategies when matched to the application.

What system components are needed to assemble the cutting system?
A complete system comprises the ISO insert, a compatible external holder or boring bar, an underlay/clamp set and replacement screws as required for secure fastening.
