A grinder is useful for grinding, cutting, surfacing, stripping, polishing, or deburring. Whether straight or angle, electric or pneumatic, this handheld device can be used for major structural works, secondary works, or finishing tasks.
Two types of grinders are used by DIY enthusiasts and professionals:
- Angle models are the most common and are used for grinding, polishing, or stripping surfaces, but also for cutting pipes, screws, or profiles;
- Straight models, known as die grinders, are used for cutting materials in hard-to-reach places.
The devices available differ in their performance and operating system.
- Corded electric models are the most used by DIY enthusiasts and professionals due to their power.
- Battery-operated electric models are suitable for non-electrified sites. They are appreciated for their mobility.
- Pneumatic models operate with compressed air. They eliminate the risk of electric shock in wet environments.
The devices offered each have their advantages.
- 115 mm diameter angle models are handy because of their lightweight. Therefore, they are suitable for precision tasks.
- 125 mm diameter angle models can be used as a grinder or a cutter. Various accessories are available, including abrasive discs, sanding plates, flap discs, or felts.
- 230 mm angle models can be used to cut concrete reinforcement bars or to remove joints in heavy-duty materials like breeze blocks or bricks.
- Straight models can be equipped with die grinding wheels, tungsten carbide burrs, wire brushes, or flap wheels. They are highly used by professionals in metallurgy.
Ultimately, the choice of a grinder depends on the work to be done, the energies available, and the working environment.
