Why Grinder Discs Should Always Be Placed Picture Facing Side Up

The correct positioning of the discs on an angle grinder is an essential aspect for both the safety and effectiveness of the tool.

According to an experienced metalworking worker, there is an important reason behind the rule of placing the discs with the printed side facing inwards.

Below, we explore the key concepts and some additional tips for working safely and optimizing the performance of this tool.

Why should the disc be placed with the face in?
Force distribution:
The discs are designed to withstand the stresses and vibrations that are generated during use. Placing them with the printed side facing inwards ensures that the fiberglass reinforcement layers and abrasive material work properly, reducing the risk of breakage.
Flange compatibility:
The printed side of many discs is manufactured to fit the tool flange perfectly. This improves the stability of the disc and prevents slippage during use.
Avoid uneven wear:
Improperly positioning the disc can cause uneven wear, which not only affects the life of the disc, but can also lead to vibrations that decrease the accuracy of the job.
Operator safety:
If the disc is improperly positioned, there is a higher chance of particles being dislodged or even the disc breaking, which could cause serious injury.
