The Carmex Small Indexable Carbide Threading Insert is a compact, full-profile tool designed for precise internal threading on CNC and manual machines. It supports ISO and UN profiles, delivering consistent thread quality across a range of materials.

• Threading type: Indexable carbide insert with full-profile geometry for internal threads only.
• Profiles supported: ISO and UN/internal thread profiles available.
• Pitch range: Compatible with pitches from 0.5 mm (32 TPI) up to 3.0 mm (8 TPI).
• Minimum bore diameter: Designed for bore diameters starting at 8.0 mm (0.31 in).
• Thread size reference: M12 x 1.75 internal thread specification.
• Coating and grade: Carbide Grade BLU with a triple-layer PVD coating for enhanced wear resistance.
• Material suitability: Effective in stainless steels, cast iron, titanium, non-ferrous metals, and most high-temperature alloys.

By combining a durable sub-micron carbide substrate with a protective PVD coating, this insert minimizes wear and maintains sharp cutting edges for clean, accurate internal threads. The full-profile design supports reliable chip evacuation and stable engagement in a minimum 8 mm bore, while the broad pitch range and ISO/UN profile compatibility give you flexibility to tackle diverse projects—from hydraulic components to precision housings—without swapping tooling mid-cycle.
