TNGG 160404 SH725 Tungaloy – ISO turning insert, triangular, 0.4 mm nose radius

The TNGG 160404 SH725 Tungaloy is an ISO-standard, triangular indexable insert designed for external and internal turning, offering a balance of toughness and stable cutting-edge performance for variable engagement conditions.

• Coated carbide SH725 grade for toughness and edge stability
• 0.4 mm nose radius for precise profiling
• Double-sided chipbreaker for consistent chip control
• Cylindrical hole for secure mounting

Higher productivity through a tough, coated grade

The SH725 designation denotes a coated carbide grade engineered for toughness and stable cutting edges, particularly suitable when tool sizes are small or cutting conditions change frequently. The coating reduces flank wear and helps maintain a consistent cutting geometry, which leads to longer edge life and fewer indexings. As a result, cycle times are lowered and overall tool cost per part is reduced without sacrificing surface integrity.

Accurate profiles and secure seating for reliable results

A 0.4 mm nose radius combined with a triangular geometry and 60° included angle provides controlled contact conditions that improve finish and dimensional accuracy during turning operations. The insert’s cylindrical hole and standardised form ensure repeatable clamping in compatible holders; stiffness is supported by the 4.76 mm plate thickness, which helps resist bending under interrupted cuts. These features together reduce vibration and contribute to predictable tool behaviour.

Consistent chip control and economical edge usage

The double-sided chipbreaker offers reliable chip formation on both faces, promoting continuous chip evacuation and reducing the likelihood of built-up edge. The reversible design increases the number of usable edges, improving cost efficiency per cutting edge. Compatibility with ISO-standard holders is determined by form, relief angle, tolerance class, fastening method, size and thickness, enabling straightforward replacement within established tool systems.

Select the right combination and get application support

Choosing the correct chipbreaker and grade for the workpiece and machining strategy is essential: SH725 is aimed at applications requiring toughness and edge stability.

FAQ

What turning tasks is this insert intended for?
The TNGG 160404 SH725 Tungaloy insert is intended for external and internal turning where a tough, edge‑stable grade is required, especially in smaller tool holders or variable engagement conditions.

What benefits does the SH725 grade provide?
SH725 is a coated carbide grade that emphasises toughness and a stable cutting edge, helping to extend edge life and maintain surface quality under changing cutting conditions.

How is the insert mounted and secured?
The insert features a cylindrical hole and follows ISO geometry; compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness for repeatable clamping and secure seating.

What does the 0.4 mm nose radius mean for finish and strength?
A 0.4 mm nose radius delivers a balance between fine profile accuracy and sufficient edge strength, improving surface finish while resisting premature chipping in typical turning operations.

Does the double-sided design affect tooling costs?
Yes; the double-sided chipbreaker increases the number of usable edges and reduces the cost per cutting edge, supporting more economical tool consumption and fewer insert changes.
