DNMG150412 AH6235 Tungaloy turning insert — PVD-coated carbide, 55° rhombic, with cylindrical hole

A precision DNMG150412 AH6235 turning insert designed for external and internal turning, optimised for machining stainless steel and applications with interrupted cuts.

• PVD-coated carbide for tough materials
• Optimised for stainless steel and interrupted cuts
• 55° rhombic geometry with cylindrical hole
• 1.2 mm corner radius for robust edge

Consistent cutting performance for demanding stainless steel applications

The PVD-coated grade AH6235 provides a balance between toughness and wear resistance, making the insert particularly suitable for stainless steel and operations with elevated risk of edge breakout. The coating reduces built-up edge and improves tool life under variable cutting conditions; combined with a carbide substrate, the insert sustains edge integrity during intermittent engagement. This results in fewer insert changes and more predictable process windows, supporting efficient batch and single-pass turning processes.

Predictable geometry and secure fixation for repeatable results

The 55° rhombic shape delivers good versatility for both external contours and internal shoulders, while the 1.2 mm corner radius enhances edge robustness without compromising dimensional accuracy. The insert is supplied with a cylindrical hole, enabling positive seating and reliable clamping in compatible holders. Compatibility to a toolholder depends on form, relief angle, tolerance class, fastening method, size and thickness; adherence to ISO standards for turning inserts simplifies selection and reduces setup time on the shop floor.

Grade and system benefits that support production stability

As part of the ISO turning insert family, this grade is configured double-sided to offer economical indexable use. The combination of the AH6235 grade and the insert geometry helps to manage chip control and resist chipping in interrupted cuts. For practical implementation, match the insert with a suitable outer holder or boring bar, plus the correct shim and clamping set, to ensure consistent contact and heat dissipation.

FAQ

Is this insert suitable for stainless steel?
The DNMG150412 AH6235 Tungaloy turning insert is optimised for stainless steel and applications with interrupted cuts, thanks to the PVD-coated AH6235 grade and a tougher carbide substrate.

What are the key dimensional and geometric specifications?
The insert has a 55° rhombic form, 15 mm size, 4.76 mm thickness and a 1.2 mm corner radius; it features a cylindrical hole for positive seating.

Can this insert be used in both external and internal turning?
Yes, the ISO DNMG form is suitable for both external and internal turning operations when paired with an appropriate outer holder or boring bar and matching clamping components.

How does the AH6235 grade help with interrupted cuts?
The AH6235 grade is designed with added toughness to resist chipping during interrupted cutting; the PVD coating aids in reducing adhesion and extending insert life.

What determines compatibility with a specific toolholder?
Compatibility is determined by insert form, relief angle, tolerance class, fastening type, size and thickness; verifying these dimensions against the holder specification ensures correct fit and clamping stability.
