Bastard File

Definition:

A bastard file is a type of file tool characterized by its intermediate level of coarseness, making it finer than a coarse file but rougher than a second cut file.

Characteristics:

  • Cut Level: Falls between coarse and second cut in terms of fineness.
  • Usage: Used for general-purpose filing where a medium level of material removal is desired.

Classification:

  • Coarse: The roughest type of file, used for rapid material removal.
  • Bastard: Intermediate coarseness, suitable for more controlled shaping and smoothing.
  • Second Cut: Finer than a bastard file, used for more precise material removal.
  • Smooth: The finest type of file, used for finishing and fine-tuning surfaces.

Applications:

  • Metalworking: Used to shape and smooth metal surfaces.
  • Woodworking: Suitable for general shaping and smoothing of wood.
  • Plastics: Can be used to file and shape plastic materials.
  • General Maintenance: Useful for various DIY and repair tasks requiring moderate material removal.

Advantages:

  • Versatility: Suitable for a wide range of materials and tasks.
  • Intermediate Finish: Provides a balance between rapid material removal and surface smoothness.
  • Cost-Effective: Often a good all-purpose file for general use.

Considerations:

  • Surface Quality: Leaves a surface that is neither too rough nor too smooth, ideal for subsequent finishing steps.
  • Durability: Should be chosen based on the material being worked on to ensure longevity and effectiveness.

Summary:

A bastard file is an essential tool for any workshop or toolbox, offering a versatile solution for tasks that require a balance between coarse material removal and finer finishing.
