Kayson Green – What are the Best Angle Grinder Discs?

When it comes to stone and metal work, angle grinders are some of the best tools on the market. Like a multi-head screwdriver, you can fit an angle grinder with a range of discs, and each one is best suited to a particular job. Choosing the right type of disc is crucial, not only for getting the job done, but also for ensuring your safety!

With this in mind, let’s look at what kinds of angle grinder discs are on offer, and what can we use them for. Here is our guide to making the right choice.

What are the Best Angle Grinder Discs

Disc Types

As we’ve touched on, each variety of disc has a specific function. Some of the most common types of discs include:

  • Wire discs – These can be used to strip and remove coatings, such as rust and paint, from surfaces.
  • Cutting discs – These can easily cut through a wide range of otherwise tough materials or surfaces.
  • Grinding discs – For removing weld seams
  • Diamond discs – These can remove the mortar from brickwork without damaging the bricks themselves.

Disc type is only one of a few factors to consider. You should pay close attention to the shape, thickness, and grain you need to consider when choosing the best disc for your angle grinder.

As with many things relating to manufacturing; always consult and abide by the manufacturer’s labelling and instructions when operating or installing power tools. If you are at any point unsure, it is likely best to enlist the help of a trained professional!

How to Choose the Right Disc for Cutting Steel

If you are looking to cut steel, pay close attention to the following:

  • Profile – The two main profiles used for cutting steel are Type 41 (Flat) and  Type 27 (Depressed Centre). Type 41 is more versatile and allows you to cut profiles and corners with ease. Type 27 works best for cutting into tight corners and overhangs.
  • Grain – Of all the grain types used for cutting steel, aluminium oxide is the most popular. This grain has a soft bond that allows for a faster and smoother cut, especially when it comes to stainless steel.
  • Thickness – The thicker the steel that needs to be cut, the thicker your disc needs to be. Between 1mm and 1.6mm works best for mild steel, including stainless steel. For sheet metal, a 1mm or 0.8mm disc will work faster and leave less waste, while thick steel will need 1.6mm through to 2.5mm.

When using your angle grinder to cut steel, make sure to use even pressure and a steady, consistent motion. Do not try to push the angle grinder: let the wheel do the work for you. Make sure to also wear safety gear such as gloves, mask, and safety glasses before use.
