Cutting disc: how to choose the ideal model
The choice of the correct abrasive or diamond disc is essential to ensure efficient, safe, and precise cutting. The market offers a wide variety of discs, from cutting to grinding and flap discs, so it is crucial to understand the specific features of each one to maximize performance and extend the service life of both the machine and the disc.
1. Identify the Material to Work On
Each material requires a specific type of disc to achieve a quality finish and avoid waste. Here are some examples:
- Metal: Cutting and grinding discs with aluminum oxide or zirconia abrasives are the most suitable for carbon steel and stainless steel.
- Concrete and Stone: Diamond discs ensure precise cuts and greater durability.
- Wood: Circular saw blades with tungsten carbide teeth are ideal for clean cuts without burning the wood.
- Ceramic and Tile: Diamond discs for dry or wet cutting prevent chipping and provide a smoother finish.
Cutting Discs
Designed for separating materials with maximum precision.
- Thin (1.0mm – 1.9mm) → Fast cuts, less burr, less effort.
- Medium (2.5mm – 3.2mm) → Greater stability, controlled cuts.
- Thick (+4mm) → Thick materials, less tendency to break.
Grinding Discs
Used for material removal and surface finishing.
- Greater thickness → Better material removal.
- Coarser grains → Higher removal rate, rougher finish.
Flap Discs
A combination of cutting and finishing, ideal for polishing and deburring.
- Flat – For flat surfaces, uniform finish.
- Conical – For edges and curves, greater material removal.
Diamond Discs
Maximum durability for cutting hard materials such as stone and concrete.
- Segmented – Fast cuts in concrete, brick, and stone.
- Turbo – Balance between speed and precision, ideal for ceramic and granite.
- Continuous – For fine and precise cuts in porcelain and glass.
3. Check the Technical Specifications
Before choosing the disc, pay attention to the following features:
Diameter and Thickness: Must be compatible with your angle grinder.
- 115mm / 125mm → Compact tools, fast and precise cuts.
- 180mm / 230mm → Higher power machines, deep and industrial cuts.
- Maximum RPM: The disc must withstand the tool’s speed.
- Mounting Type: Ensure it is suitable for your equipment.
- Safety Standards: Choose certified discs that comply with European safety regulations.
4. Tips for Better Performance and Safety
- Always use appropriate PPE, such as safety glasses, gloves, and a mask.
- Check the disc’s condition before each use.
- Avoid overheating by letting the disc work without applying excessive force.
- Store discs in a dry place protected from impacts.
