Is it safe to use an angle grinder without a protective cover?

Angle grinders without protective covers are unsafe. When using an angle grinder, the lack of a protective cover will bring a series of serious safety risks. The high-speed rotating grinding disc and cutting function of the angle grinder may splash wood chips, metal fragments, etc., which can easily injure the operator's eyes, skin and even head. In addition, if the grinding disc stops suddenly due to jamming, it will produce violent vibrations, which may cause injuries to arms and fingers. Operating an angle grinder without a protective cover can easily cause injuries such as cuts or abrasions if a part of the body accidentally touches the grinding disc.

1. Dangers of angle grinders without protective covers
1. Splashing of wood chips, dust, and debris.
During the use of angle grinders, a large amount of debris, dust, etc. is likely to be generated. These substances may be carried out and bounced by the rolling grinding disc, which may injure the eyes and cause serious accidents.
2. The grinding disc is stuck and stops suddenly.
When the grinding disc cannot roll due to some reasons, such as the workpiece is locked or too hard, the grinding disc will stop quickly, and then violent vibrations will be generated around the cross section of the grinding disc. This vibration will quickly transmit to the arm and may cause serious injuries.
3. Fingers and arms are injured.
The angle grinder is likely to get stuck when working. If the user does not turn off the power in time or pull out the workpiece violently, the grinding disc will continue to rotate due to inertia in a short time, which is very likely to cause injuries to the user's arms and fingers.
In summary, there are great dangers if the angle grinder is not equipped with a protective cover. Whether using an angle grinder in home operation or in the industrial field, safety issues must be paid attention to. Strengthen the operation of angle grinders by installing protective covers, checking the use of grinding discs, and protecting equipment to prevent accidents.
