Polishing Metal

Many use it for polishing metals, like stainless steel, and it looks better when it’s polished. You can use a die grinder to polish a huge surface, for example- shining a car. It works great when used on a vast surface because it makes work easier. Unfortunately, you cannot use a die grinder for polishing flat surfaces.  

The rotary polishing bits have a round cross-section and are perfect for polishing holes and curved surfaces. On the other hand, the mounting point polishing bits are the best for cleaning and shining the die profiles.

Sharpening Blades

You will find many die grinders that come with a blade sharpening attachment to sharpen a wide variety of blades. It is the best for sharpening knives, hatchets, axes, and varieties of blades. If you do not have a proper grindstone, it is a suitable choice for you.

Rust Removal

A die grinder is an ideal choice for those people who want to remove difficult rust. As we know that old rust can be tough to remove from metal and takes lots of time. On the other hand, a die grinder can be a great tool for efficiently removing stubborn and stuck-on rust.

With the correct attachment, use a die grinder to smooth out a wide variety of different materials like- metal, hardened steel, wood, and more.
