The Carmex Carbide Threading Insert (ACME, TiAlN coated) is a versatile, high-precision solution for threading tasks across common profiles. Designed for professionals who value durability and consistency, this insert delivers reliable performance in a compact, single-tool package.

• Five length options: Available in five lengths, ranging from 12 mm to 40 mm, to suit different workpiece sizes and tooling setups.
• Pitch range: Capable of handling pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI) for broad threading applications.
• Double-sided cutting edges: Each insert has two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD profiles), extending tool life and reducing changeovers.
• Internal & external capability: For many thread profiles, the same insert can machine both internal and external threads (with exceptions for ISO/UN/NPSM/UNJ/Acme).
• TiAlN coating: TiAlN coating provides enhanced hardness and wear resistance for longer edge life and stable performance under demanding conditions.
• Carbide construction: Robust carbide body delivers rigidity and consistent thread accuracy across tough materials and finishes.
• ACME-focused design: Specifically optimized to support ACME-thread profiles, consolidating versatility within a single carbide insert family.

This insert is built to streamline tooling inventory and improve throughput. With multiple lengths and a wide pitch range, it supports a broad set of threading tasks—from precision prototyping to production runs—while the TiAlN coating helps maintain sharpness between regrind or replacement cycles. The dual-edge design maximizes usable life, and the material and coating together deliver dependable performance in challenging materials and setups.
