Their tooth configuration enables them to work on a wide range of different metals, including softer ones like aluminium, brass, bronze and copper. This is because the regular gaps in the teeth allow waste material to escape more easily.
What are the characteristics of a millenicut file?
Cross section and profile
Millenicut files are usually available as flat or half round files. They are most often blunt, but can be flared in some instances (widening towards the tip).
Cut
Millenicut files strongly resemble single cut files.
They are characterised by one or two parallel rows of grooves cut into the surface of the file, right through its teeth.
These grooves act as chip breakers, forcing chips to break against the edge of the next tooth along in the row.
This helps to prevent clogging and also gives the file a high removal rate, i.e. it can wear a surface down quickly.
Size
Millenicut files are usually available in lengths from 200mm (8 inches) to 350mm (14 inches).
Swiss or American?
Millenicut files are neither Swiss nor American pattern cut. Their coarseness is instead measured in teeth per inch (tpi).
