7 Types of Angle Grinder Discs and Their Uses



Types of Angle Grinder Discs

Angle grinders are the unsung heroes of the workshop, capable of far more than just cutting through materials.

With a plethora of available discs, these versatile tools can tackle a wide range of tasks, from grinding metals and cutting granite to smoothing surfaces.

For those new to the world of angle grinders, the variety of discs might seem overwhelming. But fear not, for this guide is here to demystify the different types of angle grinder discs and their uses.

1. Grinding Discs

Example of Grinding Discs

Grinding discs or wheels serve as your go-to option for achieving a smooth surface, eliminating excess material, and prepping metals before welding.

As the most prevalent disc type, grinding discs come in various sizes and types, distinguished by their hardness and smoothness, denoted as grit.

For swift outcomes, opt for coarser grinding discs, though be prepared for sparks and a rough finish. Alternatively, select a less coarse disc for slower work and fewer scratches. Balancing speed and finish is the key to mastering grinding.

2. Cut-off Discs

Example of Cut-off Discs

When precise cuts through metal materials are required—be it bars, sheets, tubes, or plates—cut-off discs are your allies.

Thinner than grinding discs, they excel in making accurate cuts. However, their delicacy poses a challenge; these discs are prone to shattering, resulting in dangerous blade fragments.

Ensuring personal safety is paramount when using cut-off discs. Don the appropriate protective clothing to shield yourself from potential hazards.

3. Flap Discs

Flap Disc Example

Flap discs resemble grinding discs but specialize in finishing work. Available in various grit levels, they offer smoother results, ideal for refining surfaces. These discs shine when it comes to removing scratches and other imperfections from materials.

Remember, working with blurred or scratched metals can pose risks, so prioritize safety by donning protective gloves.

4. Wire Wheels

Wire Wheel Example

For the removal of old paint and rust from different metal surfaces, look no further than wire wheels. Comprising metal wire fibers, these discs induce abrasion on surfaces.

Distinctive in appearance, wire wheels come in various bristle thicknesses for varying levels of precision and speed.

Opt for thicker bristles when speed is paramount and precision is secondary. For intricate tasks demanding accuracy, finer bristles are your choice. Flexibility is the key to mastering wire wheels.

5. Diamond Cutting Discs

Diamond Cutting Disc Example

When dealing with masonry, stone, or granite, standard cut-off discs won’t suffice. Enter the specialized diamond cutting disc, equipped with diamond grits along its steel edge.

This unique composition lends the disc exceptional hardness and durability, enabling it to tackle even the most formidable tasks.

While diamond discs may come with a higher price tag, their unparalleled quality and performance more than justify the investment.

6. Strip Discs

Strip Disc Example

While wire wheels are effective at removing paint, they often leave a scuffed metal surface underneath. Enter the strip disc, crafted from gentle yet resilient polyfiber.

These discs adeptly remove paint and glue from metal surfaces without compromising the integrity of the underlying metal.

Preserve your work surface by employing strip discs and avoid unintended blemishes on your metal projects.

7. Polishing Pads

Polishing Pads Example

Lastly, we have polishing pads, which deviate from the cutting and grinding focus. Instead, these pads are all about adding a radiant shine to your projects.

Used for polishing surfaces, they come in various shapes and materials, each capable of creating a unique finish.

It’s crucial to use polishing pads only if your angle grinder features speed control. Not all grinders are suited for polishing, so ensure compatibility before diving into the world of shine.

In Conclusion

These are the essential angle grinder discs, each designed to serve a distinct purpose in your projects. Armed with this knowledge, your choice of disc will align seamlessly with your task at hand.

It’s prudent to keep a diverse array of discs in your toolkit, ensuring you’re prepared for any challenge that comes your way.
