Alternative Model: Makita DGA513Z 18V Cordless Angle Grinder with Slide Switch and Variable Speed (Body Only)

For users who prefer a slide switch, the Makita DGA513Z is an excellent alternative. It shares the same 18V battery platform, 125mm disc size, and variable speed control, but differs in switch design. The DGA517Z uses a paddle switch that requires continuous pressure to operate, ensuring immediate shutdown if released, which is ideal for high-risk tasks where quick stopping is essential. The DGA513Z, by contrast, features a slide switch that can be locked in the “on” position for continuous operation, making it more convenient for extended tasks but requiring careful handling.

Both models deliver the trusted Makita quality, with the DGA517Z offering enhanced safety through its paddle switch and the DGA513Z providing continuous operation convenience for prolonged tasks.

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.
