Carmex — Thread Milling & Threading Tools
Firearms are among the most thread-intensive precision components in manufacturing — barrel threads, muzzle threads, receiver threads, and suppressor mounts all demand precise, burr-free thread forms. Carmex thread mills produce the 1/2-28, 5/8-24, and proprietary thread forms common in firearms without the axial force or tap breakage risk of conventional tapping. Carmex Swiss-style Tiny Tools serve the small-diameter fire control and trigger component market on Swiss-type CNC lathes.

Rego-Fix — powRgrip Tool Holders
≤ 3µm runout makes powRgrip the standard for firearms finishing operations — barrel profiling, receiver milling, and slide machining — where dimensional consistency directly affects function and safety. The 20,000-cycle clamping warranty and sealed collet design reduce toolholder maintenance in high-volume production environments.
