Description

Carmex Small Indexable Carbide Threading Insert delivers precise internal threading for small-diameter bores. This unified full-profile design targets ISO and UN thread forms, offering reliable performance in a compact package.

  • Type: Indexable carbide threading insert for internal threads (internal-threading only)
  • Profile: Unified full-profile design compatible with ISO and UN thread forms
  • Size & Bore: T8 indexable insert with a minimum bore diameter of 8.0 mm
  • Pitch: Supports pitches from 0.5 mm (32 TPI) to 3.0 mm (8 TPI); example: 13 TPI (~1.93 mm)
  • Coating: BLU PVD triple-layer coating on sub-micron carbide grade for wear and temperature resistance
  • Materials: Effective on stainless steels, cast iron, titanium, non-ferrous metals, and most high-temperature alloys (M10–M20, K05–K20, N10–N20, S10–S20)
  • Applications: Ideal for internal threading operations in small bores where precise thread form matters

This insert is engineered to deliver consistent thread accuracy and longer tool life in challenging materials, with a coating that reduces galling and improves chip control. By supporting ISO and UN profiles across a broad pitch range, it offers flexible integration into existing tool assemblies while helping you achieve reliable thread quality in a variety of components.
