How to Safely Use Flap Discs

Flap discs are a versatile abrasive tool most commonly used for deburring, polishing and grinding a range of materials. When using flap discs, there are several things to consider to ensure you’re using the flap disc correctly and safely. Without the proper technique, equipment and protective gear, you run the risk of not only ruining your project but also seriously harming yourself. 

 

Preparation & Handling 

Before you use your flap disc, there are a couple of things to do to prepare.

Inspecting and Selecting the Flap Disc

Selecting the correct flap disc will vary based on your specific application. When choosing the flap disc with the appropriate flap disc grit and backing plate. Once you have selected your flap disc, you should carefully inspect the flap disc for any cracks, tears and any other signs of damage before mounting the disc onto the power tool. 

Using PPE 

Personal protective equipment (PPE) should always be worn when using flap discs. It’s essential to adhere to standard safety precautions and wear protective equipment including gloves, eyewear, ear protection and safety clothing.  PPE will protect you from any flying debris and the rare chance of the disc detaching/breaking from the power tool and flying at you. 

Correct Mounting 

To minimise the risk of the disc breaking from the power tool, you should ensure the disc is secured firmly and snugly onto the tool using the appropriate mounting system. Avoid over tightening as this could lead to the disc breaking. 

 

Power Tool Machine Settings and Operation

The machine settings and usage are crucial steps in making sure you’re using the flap disc safely. 

Power Tool Settings 

The power tool you’re using must be calibrated to match the flap disc’s specifications. This includes the tool’s speed and pressure. If you were to use a speed too high for the selected flap disc, you would notice premature wear and tear. This can lead to the disc not having as long of a life as it should and can lead to the disc breaking. Excessive pressure from the power tool can lead to uncontrolled operation and the flap disc breaking. 

Correct Operation Angle 

To optimise the abrasive action and reduce the risk of the disc breaking, you should maintain the correct working angle. Typically, the optimal angle is 15 to 30 degrees relative to the workpiece surface. 

Workpiece & Workplace Considerations 

Before you start and during your project, you should ensure that the workpiece is constantly secure and stable to prevent it from moving during the operation. Having a stable workpiece is essential for safe and controlled grinding/polishing. 

You should also consider the workplace around you. Remove any unnecessary clutter/objects before you begin your project to make sure your working environment is also safe. 

 

Maintaining Disc Condition and Avoiding Hazards 

Disc condition is crucial to ensure your flap disc has a long life span and is safe to use. 

How to Store a Flap Disc 

If your flap disc is not being used, you should store it correctly to extend its lifespan and protect it from potential damage. Store your flap discs in their original boxes in a dry and dust-free environment. 

Monitoring the Disc During Use 

Whilst using the flap disc for your project, you should continuously check the condition of the disc and look for any signs of wear/damage. Common signs of wear include flap separation and/or thinning. If you notice a worn disc, you should promptly replace it with a new one to optimise performance and prevent injury. 

Discarding the Disc Correctly 

For the safety of the environment, flap discs should be discarded in accordance with local regulations and environmental guidelines. If you ever have any concerns or queries about discarding abrasive/engineering products and items, it is always best practice to contact your local council.
