The TaeguTec TNMG 160408-MT TT5080 insert combines robust geometry and durable coating to deliver excellent performance in medium-rough turning operations. From the negative triangular TNMG-MT family, this insert features a 60° triangle form, 9.52 mm inscribed circle (IC), 4.76 mm thickness (S), and a corner radius (RE) of 0.8 mm. The TT5080 grade, with dual TiAlN + TiN coating, ensures high wear resistance, especially in steels, cast irons, and stainless steels—even under interrupted cuts or moderate feed/depth. Capable of maximum depth of cut ~3.5 mm and feeds up to ~0.50 mm/rev, it delivers a smooth finish, dependable edge life, and less frequent insert changes. Ideal for demanding shops in automotive, die & mold, aerospace and general engineering. Available for bulk orders—reduce per-part tooling cost and machine downtime.

Frequently Asked Questions

It performs best on steel, cast iron and stainless steel. The TT5080 grade + TiAlN/TiN coating gives good wear resistance in such materials—even with moderate hardness

  • Inscribed Circle (IC): 9.52 mm

  • Thickness (S): 4.76 mm

  • Corner Radius (RE): 0.8 mm

  • Triangle geometry: 60° negative triangle (TNMG-MT family).

Depth of cut up to ~3.5 mm; feed per revolution from ~0.17 to ~0.50 mm/rev depending on material and machine rigidity. Start toward the lower side on stainless / interrupted cuts.

Because of its durable TT5080 grade, good coating, and strong edge geometry, the tool-life is extended. There’s less frequent re-indexing or insert change, better surface finish which means less rework, and fewer machine stops—overall lowering total cost per component.

It is widely used in automotive (shafts, housings), aerospace (structural/stainless parts), die & mold (medium roughing of tool steel), and general engineering shops producing cast iron or stainless components. Any operation needing robust medium turning with consistent finish will benefit.
