Carmex's Internal Multiple Threading Insert Holder (SR0080D40-4) is a compact mill-thread tool holder designed for internal threading on CNC milling machines. It accommodates multiple carbide inserts, delivering higher cutting efficiency and reduced tool changes for precise internal thread production.

• Multi-insert capacity: Holds 4–8 inserts per holder, maximizing cutting edges per setup.
• Internal threading design: Specifically configured for internal threading applications in CNC milling with helical interpolation programs.
• Carbide insert compatibility: Built to accept carbide inserts for sharp, durable threading tools.
• Model SR0080D40-4: Dedicated internal threading insert holder engineered for stability and repeatable results.

Using this holder, you can achieve efficient internal thread milling with higher productivity and lower tooling costs relative to taps and dies. The multi-insert arrangement minimizes downtime from tool changes, while stable insert seating supports consistent thread quality across production runs. This solution is ideal for shops performing frequent internal threading on a variety of workpieces using CNC milling equipment.
