It is the shape and size <strong>of</strong> the workpiece, the material from which it is<br />
made and the desired finish that determine the choice <strong>of</strong> file. On the<br />
following pages you will find information on the areas <strong>of</strong> application <strong>of</strong><br />
the different <strong>files</strong>.<br />
Hand <strong>files</strong> are divided into four main areas: engineering <strong>files</strong>, needle<br />
<strong>files</strong>, sharpening <strong>files</strong> and milled <strong>files</strong> (including PANSAR ® blades).<br />
The <strong>Bahco</strong> range covers all <strong>of</strong> these areas meeting the requirements<br />
<strong>of</strong> most national and international standards with ample margin.<br />
The different names given to <strong>files</strong> vary according to their shape and<br />
use. The most common names are: hand, flat, half round, three<br />
square, round, square, knife and double edge.<br />
The <strong>Bahco</strong> range includes <strong>files</strong> from 4” (100 mm) in length to 14”<br />
(350 mm), depending on type. The most suitable file length depends<br />
entirely on the work to be done. The length <strong>of</strong> the file is always given<br />
excluding the tang, with exception <strong>of</strong> needle <strong>files</strong> where the total<br />
length includes the tang.<br />
The toothing <strong>of</strong> a file can vary in many different ways. Different types<br />
<strong>of</strong> cut are chosen depending on the work material, the desired rate <strong>of</strong><br />
material removal and the desired finish. The most common cuts are:<br />
single cut, double cut, Öberg cut, diagonal cut, milled cut, PANSAR ®<br />
and rasp cut.<br />
For all cut engineering, needle and sharpening <strong>files</strong>, the coarseness<br />
<strong>of</strong> the cut is given in number <strong>of</strong> whole teeth per centimetre along the<br />
length <strong>of</strong> the file. The most common degrees <strong>of</strong> coarseness are bastard,<br />
second and smooth.<br />
The main rule is that the coarser the cut, the more material is<br />
removed. If, however, a particular work operation requires a smooth<br />
finish, a file with a smooth cut should be chosen.<br />
For diagonal <strong>files</strong>, milled <strong>files</strong> and PANSAR ® blades, the degree <strong>of</strong><br />
coarseness is given in number <strong>of</strong> whole teeth per inch (“). The coarseness<br />
<strong>of</strong> the rasps is given in number <strong>of</strong> tooth tips per cm 2 .
