How To Choose The Right Angle Grinder Blade For Cutting Plastic

Balance cutting speed with smoothness and precision, depending on your project needs. Think about blade durability versus cost, especially if you expect frequent use. Also, ensure the blade size and arbor fit your angle grinder to avoid compatibility issues.
Common Mistakes And Who Should Avoid These Blades
- Expecting a single blade to work perfectly on all materials without compromise.
- Choosing blades designed only for wood when cutting harder plastics or composites.
- Using blades with the wrong arbor size that don’t fit your angle grinder.
- Buying heavy-duty diamond blades if you rarely cut stone or metal, leading to unnecessary expense.
- Assuming all blades offer smooth, chip-free cuts on delicate plastics.
