• Optimised for cast iron turning
• Double-sided chipbreaker, cylindrical hole

Faster, more consistent results for turning operations

The CVD-coated carbide in grade T505 combines wear resistance with thermal stability, producing consistently reliable cutting performance during continuous production. The triangular geometry with a 60° included angle and a 0.8 mm corner radius balances edge strength and surface finish: the modest radius increases tool life on interrupted cuts while still supporting acceptable component roughness. This results in fewer indexings and reduced non-productive time, which contributes directly to improved process efficiency and lower unit cost per part.

Material-specific behaviour and why this matters

Designed specifically for the economical machining of cast iron, the coating and substrate pairing control heat and adhesion at the cutting edge. The T505 grade is suited to a range of cast-iron alloys and cutting conditions; the double-sided chipbreaker offers flexibility when matching chip control to the chosen feed and cutting speed. For less experienced planners, a brief explanation: a chipbreaker shapes chips to avoid entanglement and improve evacuation, which in turn protects the tool edge and the workpiece integrity during turning.

Secure clamping and straightforward integration

The insert is ISO-standard, so compatibility with external holders or boring bars is governed by plate shape, clearance angle, tolerance class, fastening method, size and thickness. The cylindrical hole and the 4.76 mm plate thickness provide a stable clamping interface that reduces vibration and improves repeatability when used with the appropriate clamp set and retaining screw. This mechanical stability supports higher cutting parameters where machine rigidity and fixture design permit.

Operational benefits and lifecycle economy

Selecting an insert graded for the material and application reduces downtime for tool changes and lowers overall tooling cost. The combination of CVD-coated carbide and the triangular form enables multiple indexing positions per plate, extending useful life under stable cutting conditions. For shops seeking predictable performance, this insert supports reproducible surface quality and helps maintain cycle time targets, delivering a measurable contribution to production throughput and cost-effectiveness.

FAQ

What materials is this insert intended for?
The TNMG160408 T505 insert from Tungaloy is specified for economical machining of cast iron; the T505 grade and CVD-coated carbide substrate are formulated to manage wear and heat when turning cast-iron alloys.

How does the TNMG160408 designation relate to the insert geometry?
The designation TNMG160408 denotes the triangular form and ISO size series; the code corresponds to the plate shape and dimensions used for selecting compatible holders and fixtures for the Tungaloy turning insert.

What mounting requirements should be observed?
Mounting depends on holder compatibility: shape, clearance angle, tolerance class, fastening method, size and thickness must match; the TNMG160408 features a cylindrical hole and 4.76 mm thickness to enable stable clamping in standard ISO holders.

What is the practical effect of the 0.8 mm corner radius?
A 0.8 mm corner radius increases edge strength compared with smaller radii, improving resistance to edge chipping on interrupted cuts while still allowing acceptable surface finish in many turning applications with the TNMG160408 T505.

Is chip control addressed by the insert design?
Yes — the TNMG160408 includes a double-sided chipbreaker to assist chip shaping and evacuation, aiding process reliability and operator safety during turning of cast iron.
