Select bunnings grinding discs

When choosing a bunnings grinding discs, there are many factors to consider before buying, due to many different factors.

Here, we will study the main factors behind the selection of the bunnings grinding discs and the health and safety issues that need to be considered. After reading this buyer’s guide, you should not only have the right bunnings grinding discs, but you should take the necessary precautions to ensure that you are as safe as possible when using the grinder.

Health and Safety: The grinder can be one of the most dangerous machines in the workshop, mainly because the bunnings grinding discs is mounted on the bunnings grinding discs. To ensure that you and your workplace are safe, we recommend that you follow certain guidelines.

Speed ​​class: Before buying a grinding discs, check the running speed of the grinding machine, because this speed can never exceed the maximum speed of the bunnings grinding discs. Operating the wheel above maximum speed can be very dangerous and can cause the wheel to break or explode.

Note: Some wheels are rated in meters per minute, while other wheels are rated at per minute, so be sure to calculate before installing new wheels.

Grinding Wheel Course: In the work environment, you must attend the bunnings grinding discs training course before using this type of machine.

Many different training programs are available, but we can personally recommend XYZ health and safety training.

Wheel integrity: After unpacking, check all wheels for signs of damage during transit. If damage is found or heard (using the “ring” test), the bunnings grinding discs should not be used and should be returned to the supplier.

Storage: The wheels should be stored in a location that is not subject to rough handling or in a room where temperature changes are severe, as this can damage the bonding force of the wheels.

Machine Setup: It is important to ensure that the machine is always set up correctly, make sure the guard is in place and adjust the knife holder to the correct clearance.

Personal Protective Equipment (PPE): Always wear goggles when sanding; if dusting is not possible during dressing, you must also use a suitable dust mask. Other PPEs (eg, topcoats) are not required but are preferred.

Pumping/ventilation: When dressing the aluminium cutting disc bunnings, the appropriate method of pumping should be used to remove the grinding chips.

Main considerations
Physical dimensions: The first consideration is to purchase a bunnings grinding discs that fits the size of the grinding machine. Smaller diameter wheels can work on larger grinders, but this affects the peripheral speed, so this is not recommended as it will run slower.

Materials to be ground: Grinded or ground materials directly affect the type of abrasive required in the bunnings grinding discs. In other words, tungsten carbide tools will require a “green” silicon carbide bunnings grinding discs.

Abrasives: A wide range of abrasives are available, all with unique properties such as hardness and bond strength, making them suitable for different materials.

Granularity: This is defined by the task you are trying to accomplish. If a higher material removal rate is required, coarse grit, ie 24 g, is required. Finishing requires finer grit, such as 100g.

Glue/Binder: Adhesives are the means by which the abrasives are bonded together and will be determined again by the task undertaken. There are three main types of bonds:

Ceramic bond – mainly made of clay, the ceramic bond is strong and very hard. This is the best type of bonding when a large amount of inventory needs to be cleared.
Organic Keys – Designed for higher speeds, these keys soften under the heat of grinding. These also apply to high cutting volumes and jobs that require better surface treatment.
Rubber Bonding – Provides a smooth grinding action, which is designed for applications requiring very high quality finishes.
Speed ​​grade
Bunnings grinding discs must be used for grinders that cannot operate above their safe operating speed as this may result in crushing.
