Alternative Model: DeWalt DWE4206 Corded Angle Grinder

For users who prefer the reliability of a corded tool, the DeWalt DWE4206 is a great alternative. With a 1010W motor and 115mm disc size, it offers strong and consistent power for cutting and grinding tasks. While the DCG405FN provides cordless flexibility and a unique flat head design for accessing tight spaces, the DWE4206 delivers constant power for continuous, heavy-duty applications. Both models are ideal for professional use, with the DWE4206 offering a dependable corded solution for those not requiring the cordless advantage.


An introduction to angle grinders: Angle grinders have a wide variety of uses amongst, for example, engineers, stone masons, welders, bricklayers & scaffolders. The grinding disc is mounted on a head which sits at right angles to the motor's drive shaft. They are occasionally referred to as disc or side grinders. Cordless angle grinders are concentrated at the smaller disc diameter end of this range. Click here to see all our grinders

To choose between angle grinders: 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 5' disc diameter. Click here to see all our angle grinders

To make sure you've got the right angle grinder - 5' (125mm): Choosing the right battery: Cordless (or battery powered) tools have various chemical battery types; Li-ion is the latest technology, prior to that it was Ni-MH and Ni-Cad was the original. The higher the Ah (Ampere hours) the longer the interval between charges; the fewer times you recharge a battery the longer it will last. Some cordless tools can also come without batteries - also referred to as naked, bare units or body only. These tools are supplied without a battery or charger and more often than not without any accessoires. As a result they are significantly cheaper in price.
