Hand milled tooth dreadnought files which are made from alloy steel and have teeth which are undercut resulting in faster cutting with less effort. They may be used on all materials from aluminium to the hardest steel without clogging. The undercut and generous radius at the root of the teeth enables the file to clear itself whilst in use. Dreadnought files feature a curved tooth across the blade. Available in 8", 10" and 12" lengths.
