Carmex Carbide Threading Insert – NPSF – TiAlN Coated – 30-11.5NPSF is a versatile threading solution designed for shops that require reliable, mult profile threading with fewer tool changes. Built for precision on CNC lathes and milling machines, it delivers consistent results across a wide range of common thread profiles.
- Coating: TiAlN-coated carbide for enhanced wear resistance and higher temperature performance during threading.
- Edge configuration: Double-sided design with two cutting edges to extend tool life (note: some line variants like BSPT/NPT/NPTF/American Buttress/API RD may be single-edged).
- Internal/External capability: For many thread profiles, a single insert can machine both internal and external threads, reducing setup changes (exceptions apply for ISO/UN/NPSM/UNJ/Acme).
- Thread profiles coverage: Part of a broad family that supports all common thread profiles, simplifying inventory and tooling decisions.
- Length options: Five lengths available from 12 mm to 40 mm to fit different tools and setups.
- Pitch range: Capable of handling pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), depending on the selected length.
- Material: Durable carbide substrate designed for repeatable, high-precision threading.
This insert family translates into practical benefits: fewer tool changes thanks to multiple cutting edges, dependable performance across internal and external threading tasks, and longer tool life through a TiAlN coating that maintains sharpness at higher speeds. The five length options let you tailor depth of cut and feed rates to your specific application, whether you’re producing hydraulic fittings, fasteners, or pipe components.
