What Is the Function of an Angle Grinder (Gerinda) in Construction?

An angle grinder, commonly called a gerinda, is a versatile power tool widely used in construction

metalwork, and home improvement. Despite its small size, it performs multiple tasks that make building projects faster, safer, and more precise.


1. Cutting Materials

One of the main functions of an angle grinder is to cut through hard materials, such as:

  • Metal rods and pipes
  • Tiles and ceramic
  • Concrete or stone
  • Aluminum and steel sheets

With the right disc, it can make precise straight or curved cuts efficiently.


2. Grinding and Smoothing Surfaces

Angle grinders are also used to grind and smooth rough surfaces. This includes:

  • Removing rust from metal
  • Smoothing weld seams
  • Leveling uneven concrete or stone surfaces
  • Refining edges on wood or metal

This improves both safety and the final appearance of construction work.


3. Polishing and Finishing

With polishing discs, a gerinda can:

  • Shine metal surfaces
  • Polish tiles or stone
  • Prepare surfaces for painting or coating

This makes materials look neat and professionally finished.


4. Removing Excess Material

In construction or renovation, excess material often needs to be removed. Angle grinders help with:

  • Cutting off extra metal or bolts
  • Trimming tiles or stones
  • Removing old paint or coatings

This saves time compared to manual tools.


5. Versatility with Different Attachments

Angle grinders can perform many tasks depending on the attachment:

  • Cutting discs – cut metal, stone, concrete
  • Grinding discs – smooth edges, remove rust
  • Polishing pads – shine surfaces
  • Wire brushes – clean metal surfaces

This makes the gerinda a multi-purpose tool for any construction site or workshop.


6. Safety Considerations

While versatile, angle grinders must be used carefully:

  • Always wear gloves, goggles, and protective clothing
  • Use the correct disc for the material
  • Avoid loose clothing near spinning parts
  • Ensure the tool is properly maintained

Following safety rules prevents accidents and extends tool life.


Conclusion

An angle grinder is an essential power tool for construction and renovation projects. It allows cutting, grinding, polishing, and material removal with precision and speed. Its versatility makes it indispensable for both professional builders and DIY enthusiasts.
