Product Overview
Maximize axial load transmission with our British Buttress (BBUT) laydown threading inserts. Designed for the British standard 7°/45° profile, these tools are essential for machinery where force is applied in only one direction, such as hydraulic presses, screw jacks, and vices.
Featuring a “Full Profile” geometry, these carbide threading inserts cut the asymmetric thread groove and top the crest in a single operation. This ensures the critical 7° load-bearing flank is geometrically accurate, providing superior shear strength compared to symmetrical threads.
Key Features & Benefits
- High Thrust Capacity: The steep 7° flank angle virtually eliminates radial bursting forces, channeling the load axially.
- The 16ER Standard: Our 16er threading inserts (e.g., 16ER 12 BBUT) handle the most common medium pitches (20-10 TPI), fitting standard ISO tool holders.
- Heavy Duty Sizes: For coarser pitches (8 TPI and 6 TPI), we supply robust 1/2″ (22mm) I.C. inserts to ensure stability during deep cuts.
- Directional Options: We provide comprehensive solutions, including left hand thread insert models (e.g., 16EL 10 BBUT) for counter-rotating shafts.
