Bastard-cut half round file without handle
1.The anti rust oil on the file shall be removed before filing,or the filing powder will stick to the space
between teeth thus the filling ability is decreased.
2.The filing shall be steady and the speed shall not be too fast,relative stability shall be kept between file and machining surface,and then ideal effect will be achieved.When filing,middle convexity will occur on machining surface because of the up and down movement of the file.
3.As for quenching work-pieces with high hardness surface,it is considered first than the work-piece is grinded,or after surface layer is grinded and then second cut file/smooth cut file is used,diamond file is adopted when necessary.
4.The teeth of new file are much sharp,so you can use the new file to machine soft matal first and to machine hard metal later,as a result,the service life to file will be prolonged.
5.The file is brittle and hard because it is mde of high carbon steel,thus it can not be used for striking something else and the scraps in file shall not be removed by striking,or else the file may be broken and danger may be happened.The scraps can only be removed along the file cut direction by steel wire brush and can not be blown off with your mouth.
6.Prevent the file falling from workbench which may hurt your foot or damage something else.
