The Bahco 1-230-06-2-0 is a true rat tail file, straight for 1/3 of the toothed surface at 6mm diameter, and then gently tapered for the remaining two thirds, down to about 4mm diameter at the tip. Second cut toothing provides rapid material removal and, with care, a surface that requires little or no further finishing.
For best results, advance the file with even pressure to bring the maximum number of teeth into contact with the work. Roll the file slowly as you push through the stroke and then lift off on the return stroke to avoid dulling the cutting ridges.
To clean your files gently brush out any accumulated debris with a soft wire brush or file card, always going along the ridges rather than across them. To minimise the chances of the file clogging when working with soft metals, apply chalk liberally to the surfaces before you begin.
