DCMT11T304 AH6235 – Indexable Turning Insert for Turning | Tungaloy

DCMT11T304 AH6235 is an ISO rhombic indexable insert designed for external and internal turning, optimised for interrupted cuts and challenging rostfreier Stahl applications

• PVD-coated carbide for tougher edges
• Designed for rostfreier Stahl and interrupted cuts
• Rhombic 11 mm form with 55° cutting angle
• Central hole with countersink for secure clamping

Stable cutting performance for interrupted and tough materials

The PVD-coated carbide grade AH6235 provides a balance of toughness and wear resistance that targets the common challenges of turning, especially with rostfreier Stahl and interrupted cuts. By choosing a tougher grade, the risk of notch formation and premature chipping is reduced, which in turn extends in-process lifetime and lowers the frequency of tool changes. The rhombic 11 mm geometry with a 55° cutting angle and a 0.4 mm corner radius helps maintain cutting-edge stability while delivering predictable chip flow with the one-sided chipbreaker.

Reduced downtime through predictable edge behaviour and secure clamping

A central mounting hole with a cylindrical bore and single-sided countersink (40°–60°) ensures reliable clamping in standard ISO toolholders, which simplifies tool replacement during production. The insert’s 7° clearance angle and plate thickness of 3.97 mm contribute to consistent clearance and strength under varying forces, so set-up times are shortened and repeatability improves. These mechanical features combine to offer measurable efficiency gains in batch production and short-series machining.

Practical integration and material-specific guidance

The ISO designation makes this insert compatible with typical ISO turning holders when form, free angle, tolerance class, fastening method, size and thickness are matched; compatibility verification is recommended before first use. The PVD-coated surface improves resistance to built-up edge in tough alloys while the chosen grade supports machining where frequent interruptions or edge impact occur. Select cutting data geared to the workpiece and machine rigidity to exploit the insert’s advantages for surface finish and life.

FAQ

What materials is this insert best suited for?
The DCMT11T304 AH6235 insert is optimised for rostfreier Stahl and other materials where toughness and resistance to edge chipping are required; the AH6235 grade with PVD coating improves performance in interrupted cuts.

How does the insert secure to the holder?
Clamping is achieved via the central cylindrical hole with a one-sided countersink (40°–60°), providing secure fixation in compatible ISO turning holders for the DCMT11T304 insert (SKU 6890178-Tungaloy).

What benefits does the PVD coating provide?
The PVD-coated carbide composition of this indexable insert increases wear resistance and helps prevent built-up edge, contributing to longer in-service life and more consistent surface quality during turning.

Is the geometry suitable for finishing operations?
With a 0.4 mm corner radius and a 55° cutting angle, the insert balances strength and cutting precision; it can be used for semi-finish and certain finishing tasks when combined with appropriate feeds and speeds.

How should the insert be specified when ordering spare parts?
Order using the ISO designation and grade—DCMT11T304 AH6235—and the manufacturer article number 6890178 or SKU 6890178-Tungaloy to ensure original Tungaloy inserts are supplied.
