TNMA 220412 T5125 — ISO turning insert by Tungaloy

TNMA220412 T5125 is an ISO‑standard indexable turning insert for external and internal turning in demanding, intermittently loaded conditions.

• ISO TNMA geometry for wide compatibility
• CVD‑coated cemented carbide T5125 grade
• 1.2 mm corner radius for robust cuts
• Triangular insert with cylindrical hole

Engineered for consistent performance in interrupted turning

The CVD‑coated cemented carbide grade T5125 is formulated for toughness under interrupted cutting and less rigid set‑ups, giving stable chip formation and extended edge life. The triangular geometry with a 1.2 mm corner radius helps resist edge chipping during plunge or interrupted passes, while the CVD layer improves wear resistance on abrasive surfaces. These properties translate into fewer tool changes and more predictable cycle times on cast‑iron components, supporting a more efficient production flow.

Straightforward integration into ISO tooling systems

Compatibility is governed by the insert's form, clearance angle (0°), tolerance class, fastening method, size 22, and thickness 4.76 mm, so selection of the matching holder and clamping set is essential for secure clamping and repeatable results. The insert’s cylindrical hole supports standard screw fixation, simplifying replacement and inventory management. As an ISO‑specified part, the insert fits into common TNMA holders, which reduces setup complexity and shortens machine downtime during tool changes.

Practical handling that reduces downtime and improves process reliability

With no built‑in chipbreaker, the cutting edge relies on the grade and geometry to manage chips; this allows flexible adaptation to different cutting strategies or the addition of a tailored chip control solution when needed. The combination of CVD coating, cemented carbide substrate and the TNMA form provides a dependable balance between wear resistance and toughness, particularly for cast‑iron turning under interrupted loads. Clear marking and consistent tolerances support fast insert indexing and predictable surface outcomes, contributing to process stability and cost efficiency.

FAQ

Which materials is the insert best suited for? The TNMA220412 T5125 indexable insert is primarily designed for cast iron, especially where interrupted cuts or less stable conditions occur; its toughness and coating provide reliable performance on abrasive cast‑iron grades.

What are the key geometric specifications of this insert? The insert features TNMA geometry with a 22 mm size, 60° included angle, 1.2 mm corner radius, 4.76 mm thickness and a cylindrical hole for secure fastening; these dimensions correspond to the TNMA220412 designation.

Is the insert suitable for interrupted cuts? Yes — the T5125 grade and the robust corner geometry make the insert suitable for interrupted turning and applications where edge stability is critical.

How is holder compatibility determined? Holder compatibility depends on the insert form, clearance angle (0°), tolerance class, fastening type, size and thickness; selecting a matching TNMA holder and the correct clamping set ensures secure mounting and repeatable results.

Does this insert include a chipbreaker? No — the TNMA220412 T5125 insert is supplied without a chipbreaker; chip control should be achieved by selecting the appropriate grade, cutting parameters or a dedicated chip control insert design.
