Safety

Angle grinders are one of the most dangerous tools in the workplace, and you must first have the proper training to use the tool safely. The disc rotates at incredibly high speed (between 9,000 to 11,000 rpm). So you must learn the correct techniques of holding the tool firmly when the disc rubs against the surfaces and generates vibration besides sending off sparks that can burn the skin. Use hand gloves and safety goggles for protection and take precautions against accidents from discs or attachments breaking away during use. Besides having proper training in using Angle grinders, you must also respect the tool and understand its safety features.

Angles grinders must have the standard set of safety features like the kickback brakes that bring the tool to a dead stop whenever it senses some obstruction. This feature prevents the tool from slipping away from your grip due to the impact of sudden disruption. Choose a tool with a two-stage trigger that requires deactivating the safety switch to allow the trigger function. This feature prevents the tool from starting accidentally when changing the disc.

The tool must have some vibration arresting features like anti-vibration handles that can absorb about 60% vibration. This reduces the uncomfortable feeling that can develop when using the machine for a long time, which can eventually lead to the numbness of the hands.

The tool comes with a built-in guard around the disc, and you must never try to remove it as it only increases the risks of accident and injury.

Why choose cordless grinders?

The power outlet required to run any power tool is often a hindrance.  It might not be available at all places, and even if available, the length of the cord could be limiting the flexibility of using the tool if it is not long enough to reach out to the farthest point of the workplace. Besides, the winding cord that dangles from the tool needs careful handling to protect users from electrical shocks, and they must ensure that the cord does not interfere with the work surface, which can cause accidents.  The cord can be problematic to handle in certain situations and even reduce work speed by creating traction.

To take care of all such problems, professionals are using cordless grinders powered by batteries that give them more liberty to work with the tool. As the cordless tool does not require plugging into a power outlet, you can use it anywhere regardless of the availability of electrical power. It is safer to use the device in confined spaces while accessing every nook and cranny with equal ease. Although cordless grinders cost you more than the cordless variety, the convenience of use pays back much more than you invest.
