DNMG150408 T9235 DNMG Turning Insert by Tungaloy — CVD-coated carbide, 0.8 mm radius

A DNMG150408 T9235 indexable insert for turning, designed for external and internal turning of steel where interrupted cuts and limited stability demand a tough, reliable grade.

• CVD-coated carbide grade T9235
• Tough grade for interrupted cuts
• ISO rhombic DNMG geometry
• 0.8 mm corner radius, 55° lead angle
• Double-sided chipbreaker with cylindrical hole

Consistent metal removal and predictable tool life

The combination of a CVD-coated carbide substrate and the T9235 tough grade delivers predictable performance when machining steel at moderate cutting speeds. The coating enhances wear resistance while the substrate resists chipping under impact, so the insert sustains material removal even with interrupted cuts. This leads to fewer unscheduled tool changes and a steadier production flow, supporting higher overall process efficiency and lower per-part tooling costs.

Stability in unstable set-ups and interrupted operations

Where rigidity is limited or cuts are frequently interrupted, the toughened carbide composition provides improved fracture resistance compared with standard grades. The 0.8 mm corner radius and rhombic DNMG form produce a balance between edge strength and surface finish, reducing the risk of chipping during abrupt tool engagement. Choosing this grade and geometry therefore supports reliable batch processing and reduces the risk of scrap in sensitive turning operations.

Clear compatibility and straightforward mounting

The insert is supplied in the ISO DNMG form (ISO code 150408) with a cylindrical hole and is compatible with standard DNMG external holders and boring bars when matched by form, relief angle and tolerance class. The 55° lead angle and 0° relief require attention during holder selection; selecting a holder with matching seat and clamp geometry ensures repeatable positioning and secure clamping. This alignment reduces vibration and improves dimensional consistency part-to-part.

Practical materials and applications explained

Manufactured from carbide and finished with a CVD coating, the grade is tailored primarily for machining steel in conditions where toughness is prioritised over maximum cutting speed. The double-sided chipbreaker design allows economical use of each insert face, and the plate thickness of 4.76 mm supports stable seating in standard toolholders. For external and internal turning tasks where interrupted cuts, unstable set-ups or variable workpiece conditions occur, this insert offers a robust, economical solution.

FAQ

What materials is this insert intended for?
The DNMG150408 T9235 insert is optimised for steel machining; the CVD-coated T9235 grade emphasises toughness for interrupted cuts and less stable conditions.

Can the insert be used on both external and internal turning applications?
Yes, the rhombic DNMG form and cylindrical hole allow use in both external holders and compatible boring bars for internal turning when the holder geometry matches the insert form and clearance.

How does the T9235 grade perform compared with general-purpose grades?
The T9235 grade offers increased resistance to chipping and breakage under interrupted cuts due to its tougher carbide substrate combined with a wear-resistant CVD coating, improving process reliability in challenging set-ups.

What key dimensions should be checked before ordering holders?
Ensure compatibility with the ISO code 150408, the 0.8 mm corner radius, the 4.76 mm plate thickness, the 55° lead angle and the presence of a cylindrical hole for correct clamping and seating.

Is the insert reversible and economical in use?
The double-sided chipbreaker design permits indexation of two cutting edges per insert, extending the service life per item and improving cost efficiency for batch operations.
