The Carmex Carbide Threading Insert for ACME threads with TiAlN coating is built for professional machinists who need versatile, reliable threading across common profiles. Designed to withstand demanding turning operations, it delivers consistent, precise results in a compact, cost-efficient package.

• TiAlN Coated Carbide: Hardened, heat-resistant coating enhances wear life and allows higher cutting speeds for durable, repeatable threads.
• ACME Threading Focus: Specifically suited for ACME thread forms, addressing the needs of power screws and precision lead screws in mechanical assemblies.
• Five Length Options: Available in five lengths from 12 mm to 40 mm to match tool geometry and depth of cut without changing inserts.
• Wide Pitch Range: Handles pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), covering a broad spectrum of standard thread sizes.
• Double-Sided Cutting Edges: Two cutting edges per insert for extended edge life and reduced downtime (except for BSPT/NPT/NPTF/American Buttress/API RD profiles, which are single-edged).
• Internal/External Capability: For many thread profiles, the same insert can machine both internal and external threads; note exceptions apply for ISO/UN/NPSM/UNJ/Acme profiles.

This insert is ideal for machine shops and CNC operators who value versatility, long wear life, and the ability to tackle multiple threading tasks with a single, well-coated tool. Use at appropriate speeds and feeds, with suitable coolant, to maximize edge life and finish quality across steel, cast iron, and other common metals. The TiAlN coating helps sustain performance under heat-intensive conditions, while the dual-edge design reduces tool changes and improves productivity on busy milling and turning centers.
