Japanese milled-tooth side float. These files cut with surprising speed, yet leave a remarkably smooth surface. This is because the teeth, which are milled and then chemically etched to a sharp edge, don't abrade material; they shear it, leaving shavings instead of dust.
Japanese milled-tooth side float.
These files cut with surprising speed, yet leave a remarkably smooth surface. This is because the teeth, which are milled and then chemically etched to a sharp edge, don't abrade material; they shear it, leaving shavings instead of dust. The diagonal groove pattern enables the teeth to act as a series of chip breakers by decreasing the width of each tooth, reducing clogging.
