Introducing the Carmex Carbide Threading Insert for BSPT, TiAlN-coated and ready to handle 14-19 BSPT threads with dependable precision. This versatile carbide insert is designed for machinists who need consistent BSPT threading performance across common profiles, in a compact, easy-to-use format.
- Coating: TiAlN-coated carbide for improved wear resistance and better heat tolerance at typical threading speeds.
- Material: Solid carbide construction delivers rigidity and long edge life for repeated threading cuts.
- Edge configuration: Double-edged design with two cutting edges on most variants, maximizing usage per insert (exceptional cases for BSPT/NPT/NPTF/American Buttress/API RD).
- Length options: Five lengths available, from 12 mm to 40 mm, to fit different tooling setups and workpiece clearances.
- Pitch range: Depending on length, supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI) for broad BSPT threading coverage.
- Internal/External threading: For many thread profiles, the same insert can machine both internal and external threads, reducing tool inventory (with profile-specific exceptions).
This insert is ideal for workshops and production environments that frequently work with BSPT and tapered-thread components. The TiAlN coating helps sustain cutting performance under higher speeds and heavier cuts, while the carbide body provides dependable stiffness and precision. Use the five available lengths to adapt to different hole depths and threading needs, and take advantage of the two-cutting-edge design to maximize each insert’s lifespan. Whether you’re threading pipe fittings, valves, or other BSPT components, this Carmex insert delivers consistent results with less downtime and fewer tool changes.
