Meet Carmex Carbide Threading Inserts—your versatile solution for precision threading across common profiles. Perfect for machine shops and CNC operators who need reliable, durable inserts that cover a wide range of thread types without constant tool changes.
- Coating: TiAlN-coated carbide inserts deliver enhanced wear resistance and heat tolerance for consistent performance at higher speeds.
- Cutting Edges: Double-sided design provides two cutting edges per insert, extending usable life (except for BSPT/NPT/NPTF/American Buttress/API RD profiles).
- Thread Profiles Covered: A comprehensive collection that supports all common thread forms, reducing the need to stock multiple separate tools.
- Operating Lengths: Available in 5 lengths from 12 mm to 40 mm to match your machining setup and reach requirements.
- Pitch Range: Handles pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), depending on the chosen length.
- Internal/External Capability: For many thread profiles, the same insert can machine both internal and external threads (except ISO/UN/NPSM/UNJ/Acme).
- Compatibility: Optimized for NPS-threaded workpieces, aligning with common piping and mechanical assembly applications.
These inserts are designed to deliver dependable thread quality across a broad range of jobs—from standard fasteners to pipe fittings. The combination of TiAlN coating, multi-edge geometry, and length/pitch options helps you reduce tool changes, simplify inventory, and maintain consistent results on both interior and exterior threads. Ideal for general machining, maintenance workshops, and production environments where versatility and reliability matter most.
