Flat Files (Bastard Cut) are double-sided handheld files that are both bastard coarseness and double cut. The coarseness refers to how quickly and aggressively the file can remove stock. Bastard cuts are the intermediate between the coarsest and the second cut coarseness. This level of coarseness allows for ample material removal at a rapid pace while still creating a smooth finish. Double cut refers to the fact that the file was cut twice, one cut on top of the other, in opposite diagonal directions. This double cut results in two sets of teeth at opposite angles in a crisscross pattern. Having these two opposing cuts allows for more aggressive removal of material and more pressure is often used with double cut files than single cut files to take advantage of this design. These flat bastard files are also tapered at the tip to allow for more detailed work. These double cut flat bastard metal file tools are commonly found to be used by those who require aggressive stock removal, such as repairmen or machinists. This hand file can be used for general stock removal purposes as well as de-scaling, die casting, die forging, foundry casting.

* For safety reasons, a file should never be used without a handle. Clean with a wire file cleaner if it gets clogged.
