WHAT ARE THE BEST CUTTING DISCS FOR STEEL ? DIY users approaching projects in the metal fabrication field, where steel cutting is required, always have an initial question on what is the best abrasive product to efficiently cut through both stainless steel and mild steel. There are a few key determinants to selecting both the appropriate power tool for your project, and the most effective steel cutting abrasive for your project. For DIY users these factors depend largely on what type of material needs to be cut, the thickness of the metal that needs to be cut, and the accessibility of the metal area that needs to be cut. We aim to go through the best abrasive for the job below. WHAT ARE THE BEST CUTTING DISCS FOR STEEL ?

Choosing Thickness of Cutting Wheels Cutting discs are available in different thicknesses, and the type of wheel you select depends on the type, shape and thickness of the steel 5″ 125mm Side Angle Cutting Discthat needs to be cut. For standard everyday jobs on either stainless or mild steel using an angle grinder, choose a 1mm or 1.6mm thickness in your disc. For projects that involve thin metal such as sheet metal, choose a 1.0mm or 0.8mm thinner cutting disc. These thinner discs will sheet metal faster and as such, minimise discoloration and leave less work in the clean-up of the surface of the metal once you’re done. When working with Aluminium, best results it is recommended to apply cutting wax or other type of saw lubricant to the cutting disc to preserve the life of the blade and avoid chipping. For heavier steel cutting jobs where you need to cut through a significant thickness of metal, select a 1.6mm or 2.5mm thickness of cutting disc. However, it is important to note that thicker wheels cut slower and generate more friction and heat through the cut — often discolouring the workpiece and requiring additional steps to finish.
