4' (100mm) angle grinders, as the name suggests, accept grinding discs up to 100mm in size. These grinders are relatively small in size, and are suitable for smaller jobs. The size of disc that the grinder can accept dictates the depth of cut that the grinder can achieve. These grinders therefore can only make relatively shallow cuts.
- Disc diameter is the key choice to make when selecting an angle grinder. They range in disc diameter size from 4' (100mm) - 9' (230mm) with the 4.1/2' (115mm) & 9' (230mm) grinders being the most popular choices. Smaller grinders rotate the discs at a higher speed. These tools all have a 4' disc diameter.
- Choosing your power source: 240v tools are used with normal mains power whilst 110v tools are used on construction sites for safety reasons.
