DPMT 11T302 AH6225 Turning Insert (Tungaloy) – 55° approach, 0.2 mm radius

The DPMT11T302 AH6225 is a rhombic, ISO-compliant turning insert engineered for external and internal turning, offering a sharp yet robust cutting edge for medium-duty machining of rostfreie Stähle.

• PVD-coated cemented carbide grade AH6225
• 55° approach angle for versatile turning
• 0.2 mm corner radius for precise profiles
• Rhombic ISO insert with cylindrical hole

Predictable cutting performance for mixed production

The combination of a PVD-coated surface and a cemented carbide substrate provides consistent wear resistance and reliable edge behaviour under changing conditions. The AH6225 grade is formulated as a universal option for rostfreie Stähle, balancing a sharp cutting edge with sufficient toughness to withstand interrupted cuts and variable feeds. PVD coating reduces adhesion and improves thermal resilience; in practical terms this means longer tool life and fewer insert changes, which supports steady cycle times and lower tooling-related downtime.

Geometry that supports accuracy and process stability

A rhombic, ISO-compliant geometry with a 55° approach angle and 0.2 mm corner radius delivers both access to tight profiles and control of cutting forces. The 3.97 mm thickness and the cylindrical hole with a single-side countersink (40°–60°) ensure positive clamping in standard holders; compatibility is determined by shape, clearance angle and tolerance class. For shops transitioning between external and internal turning, this geometry helps maintain surface finish and dimensional repeatability while reducing the need for multiple specialised tools.

System integration and application advantages in the workshop

Designed for use in a typical ISO insert system—insert, compatible external holder or boring bar, clamp set and replacement screws—the component simplifies logistics and inventory. The single-sided chipbreaker provides effective chip control for many turning operations, lowering the risk of entanglement and improving machine uptime. When fitted in a stable holder and paired with appropriate speeds and feeds, the insert supports efficient material removal with predictable tool life, contributing to a cost-effective production flow and higher first-pass yield.

FAQ

What materials is this insert intended for?
The DPMT11T302 AH6225 insert is specified for machining rostfreie Stähle and is formulated to balance edge sharpness and toughness for medium turning tasks.

How does the AH6225 grade affect performance?
AH6225 is a PVD-coated cemented carbide grade; on the DPMT11T302 it offers improved wear resistance and reduced adhesion, leading to longer, more consistent tool life in varied production conditions.

Which holder types are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and insert size; the rhombic DPMT geometry fits standard ISO external holders and boring bars designed for 11 mm inserts.

What advantages does the 0.2 mm corner radius provide?
A 0.2 mm corner radius on the DPMT11T302 enables precise profile turning with reduced risk of breakage on light interruptions, while maintaining a good surface finish on typical turning passes.

Is the clamping arrangement standardised?
Yes; the insert features a cylindrical hole with a single-side countersink (40°–60°) for secure, standardised clamping in compatible ISO systems.
