10" / 250mm Round Bastard Cut File

Gripwell 10" / 250mm Round Bastard Cut File. High Carbon steel hardened tempered with rust preventative finish as the file is dipped in rust preventative oil. 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. Size: 10-Inch / 250mm.
