Premium Performance from JET-KUT files:
- JET-KUT files are cut from high chrome alloy steel for increased hardness and strength
- Through a process of annealing the file blank is heated to a high temperature and then cooled slowly under controlled conditions to soften the steel for tooth cutting and to ensure uniformity in the internal structure
- The teeth are then formed by a hardened chisel that cuts into the soft blank to raise the steel into the desired tooth formation
- JET-KUT files are then repeatedly heated to a controlled temperature and quenched in a special quenching solution to maximize the hardness of the cutting edge
- Next, the files are straightened without reducing hardness to ensure the entire surface delivers maximum cutting performance
- A series of tests are performed on finished files by trained inspectors to ensure a high quality cutting tool every time
