Deburring tools are used on a variety of surfaces to remove burrs and ridges that are left on products after they are manufactured. For example, a hole deburring tool is used to remove any burrs from the inside of a hole which would prevent screws from fitting properly.
An external deburring tool is one that goes along the exterior of an object to remove any burrs (which you probably figured out from the name already). It can be used in many different circumstances, some of which are explained below.
To Clean Up Pipes or Shafts
External deburring tools are vital when you are working on a cylindrical piece such as a pipe or a shaft. The exterior finish of these objects needs to be perfectly smooth for handling and functionality, but the carving process often leaves behind burrs. A deburring tool that goes over the exterior of the object is often the all-important last step in the manufacturing process.
To Clean Up Threaded Objects
When manufacturing threaded pieces such as bolts, there are usually many burrs. The manufacturing process carves up the entire surface, so it makes sense that there will be more burrs than if it was just smooth. However, burrs can make a threaded bolt unusable because they affect the precise fit of the object.
In these cases, an external deburring tool is vital to ensure the perfect fit of the object. Plus, a professional tool is the only way to remove all of the burrs, as manual finishing will take too long.
