Carmex Small Indexable Carbide Insert - Threading Partial Profile 60° - T8 - 8.4mm Min Bore

Carmex Small Indexable Carbide Insert with a 60° threading partial profile delivers precise internal threading performance in compact bores. Designed for a wide range of metals, it combines a durable carbide body with a protective BLU PVD coating to extend tool life.

• Profile: 60° threading partial-profile insert for controlled chip formation and consistent thread geometry.
• Carbide Grade / Coating: Sub-micron BLU PVD triple-layer coating on a carbide insert for extended wear resistance in demanding materials.
• Minimum Bore: 8.0 mm (0.31 in) minimum bore diameter compatibility for internal threading tools.
• Pitches: Available for pitches from 0.4 mm (364TPI) to 3.0 mm (8TPI) to cover common metric and imperial thread forms.
• Material Compatibility: Suitable for stainless steels, cast iron, titanium, non-ferrous metals, and most high-temperature alloys (M10–M20, K05–K20, N10–N20, S10–S20).

This insert delivers clean, accurate threads with reduced wear thanks to the BLU coating and sub-micron carbide substrate. Its indexable design lets you swap in a fresh insert instead of grinding a new tool, improving uptime on threaded bore operations and reducing part rejection from imperfect threads. The range of pitches supports both fine-pitch and coarse-pitch threaded holes, making it a versatile choice for fasteners, fittings, and hydraulic components across stainless steels, iron, titanium, and high-temperature alloys.
