In this video we show you how to get the best from your cutting disc and angle grinder. With these tips and tricks, you can minimise and even prevent bluing, burning and burrs when you're cutting, avoiding costly rework and use of additional tools. 

When cutting metal, the heat generated from the rotation of the disc can cause the metal to burn, this is known as bluing. The more friction, pressure and heat that builds up, the more bluing you'll see. This not only looks bad, but it takes additional time to rectify and remove using additional fabrication processes. 
The creation of burrs; tiny sharp bits of metal along the cutting edge, is also common when cutting. These can not only be dangerous, but they also take time to grind off with other abrasive tools.
