As you can see in this video, there are several different attachments to use with your angle grinder when working on metal.
- Grinding Wheels
- Cut-off Wheels
- Abrasive Grinding Pads
- Metal Flap Discs
- Wire Wheels and Brushes
A grinding wheel is a consumable wheel used for a variety grinding and abrasive machining operations. Grinding wheels are generally made from a matrix of coarse abrasive particles pressed and bonded together to form a solid, circular shape with various profiles and cross sections available depending on the intended usage for the wheel.
There are also some types of grinding wheels made from a solid steel or aluminum disc with particles bonded to the surface. Not unlike sand-paper, grinding wheels are made with varying degrees of coarseness.
Grinding wheels can be used to de-bur, sharpen, smooth and even cut metal.
Cut-off wheels are made specifically to cut metal. They are very similar in design to grinding wheels.
These abrasive metal cutting wheels are essentially a very thin version of the grinding wheel. Instead of simply grinding large areas of metal like grinding wheels however, cut-off wheels are made to cut through metal with a minimal amount of waste.
Use a cut-off wheel to cut pipe, re-bar, sheet metal, plate and even dimensional steel.

In this video you see how easy it is to polish metal using your angle grinder and the appropriate grinding pads and abrasive flap discs.
Grinding pads are very similar in nature to traditional sand-paper. These abrasive pads are available in a variety of grits and need to be installed on your angle grinder using a backing pad or rigid disc.
When using grinding pads on your angle grinder think of the metal just as you would when sanding wood. Always start with a heavy grit like 36 or 50 grit and work your way up to the lighter grits like 100 grit to 120 grit.
Use grinding pads to knock off the bulk of the unwanted metal before moving on to the abrasive flap discs.
Abrasive Flap Disks
When you are looking for a fine, polished or seamless effect on metal, you will want to use an abrasive flap disc attachment on your angle grinder.
Not unlike grinding wheels and pads, these flap discs are also available in a variety grits all the way up to the very fine 220 grit discs. As you will see in this image, abrasive flap discs get their name because of the manner in which they are designed.
Wire Wheels and Brushes
Now when it comes to your angle grinder and working on metal, no tutorial would be complete without addressing wire wheels and brushes.
Wire wheels remove rust and flaking paint from metal quickly. Wire wheel and brush attachments are designed for different types of stripping, cleaning and deburring tasks.
Wire cup brushes work best for stripping paint or rust from broad, flat areas on metal while wire wheels fit into crevices and corners more easily. Wheel and brush attachments come in a wide variety of styles.
Just like all the other angle grinder attachments covered in this tutorial, always read the packaging to find one that works best for your application.
Hope this is helpful the next time you need to grab that angle grinder to work on metal.
