Buying Guide

We have provided you with a brief guide on how to pick the best metal files for your needs. To purchase the right one, you need to focus on every feature of the tool.

Materials used for manufacturing metal files

Manufacturers have used hardened carbon steel to design these tools. In most cases, they use hardened carbon steel that lasts long. It is also essential to know what you can file with these small tools. The reliable and versatile tools enable you to file glass, metal, and plastic. 

Shape of files

You can find metal files of a range of shapes, like square, round, pointed, and half-round. Based on the shape that you need, you may choose the file.


You need to check out the tool size mentioned by manufacturers. However, while you have chosen a metal file set, you will find tools of different sizes. The overall size also affects the weight of the metal file and your comfort of using them.


When you are checking the construction of your metal file, you have to focus on the handle. The best tools always have a rubber grip to ensure comfort. Moreover, some of them have detachable handles, and while storing your tools, you may remove them.  

Safety edge

It refers to the smooth and flat side of your flat file. In some cases, when you need to protect the adjacent surface from metal filing, this feature is important.

Identify the style of teeth

The most important factor is to check the durability of the teeth. You must also analyze the coarseness level of your files. The teeth of these files help you in making sharp cuts. With the best quality teeth, you can save your efforts in dealing with metals and other objects.

With a longer file, you will find a fewer number of teeth per inch. You will have a coarser cut. Some other types of cuts are-:

  • Middle
  • Rough
  • Bastard
  • Smooth
  • Second Cut
  • Dead Smooth

Thus, the file length and teeth play a role in differentiating cuts.

Metal files: Categories

We can categorize metal files in a range of ways- 

  • Diamond files: With industrial diamonds added to the surface, these files are usable with tough surfaces, like steel and hardened carbide. 
  • Needle files: These files have cross-sectional shapes, and you can apply them on any uneven and inaccessible surface.
  • Hand file: You can notice a variation in the thickness level of these square-edged files. 
  • Flat file: It is a thick file with a narrow design at the edge.
  • Mill file: It has a very narrow and thin profile.
  • Square file: It has 4 cutting edges for large rectangular openings.
  • Round file: You may use it for making large and round openings and smoothening metal objects. 
  • Triangular file: As it has 3 cutting sides, we call them triangular files. You may also use it to sharpen your tools.


Now, you can pick the right one of the best metal files. Our buying guide and reviews will help you in buying the perfect tool. Use metal files for shaping metals and several other objects. 

You must also know about single and double-cut. The single-cut metal file has teeth in one direction. You can use it to sharpen scissors and other tools. The double-cut enables you to cut in two directions. You may apply it to remove rust and smoothen wood objects with slight pressure.
