An abrasive disc attaches to a power tool or fixes to a bench tool and makes easy work of cutting, shaping and sanding workpieces in all kinds of materials.
Abrasive discs are manufactured in a huge variety of types, materials and grits, they're an essential piece of equipment in a modern trade toolkit.
There's a wide range of abrasive discs available on the market, to suit many applications including cutting, polishing, cleaning and deburring on a vary arrange of materials that include plastic, metal and wood.
There's a wide range of abrasive discs available on the market, to suit many applications including cutting, polishing, cleaning and deburring to name a few.
• Coated discs - These are used widely for surface finishing applications
• Cutting discs - This type of abrasive disc is available in various classes and materials and are used to cut, rough and sand a workpiece
• Diamond discs - Used in conjunction with grinders and sanders, these discs are used for grinding and polishing granite and other stone workpieces
• Fibre discs - Also called vulcanised fibre discs, these discs feature a layer of vulcanised fibre coated with a combination of resin and abrasive
• Flap discs - A versatile abrasive disc, they're made up of layers of abrasive with overlapping sections where the disc curves. As they're used, spent abrasive makes way for new, fresh abrasive for a long-lasting product
• Grinding discs - These discs are available in various thicknesses to cut and remove corrosion and welding splash
• Net discs - These sanding discs feature a netting structured abrasive on a foam backing. Dust slips through the net abrasive and is captured in the foam to provide relatively dust-free sanding
• Non-woven discs - Made from bonded synthetic fibres, these abrasive discs are used for cleaning and finishing various materials
• Non-woven flap discs - Made from bonded synthetic fibres, sheets of non-woven abrasive are layered and overlapped on the curves of the disc. When in use, spent abrasive makes way for new and fresh abrasive for an even finish
• Plastic filament discs - These abrasive discs are made up of brush-like SiC or nylon filament coated with abrasive, and are ideal for deburring and finishing
• Stripping discs - These extra coarse discs are made with silicon carbide and are used to clean away corrosion, paint and coatings on tough materials
• Unitised discs - Used for metalwork, these discs are made from reprocessed synthetic fibres an give a clean and consistent finish
• Application - the type of application is the most important factor in choosing the right abrasive disc. Whether cutting, sanding or finishing the disc must be chosen to suit the task.
• Grit - the right grit, whether coarse or fine will help you to achieve the desired finish.
• Disc diameter - ensure the abrasive disc is compatible with the power tool you'll be using it with.
• RPM - similar to the disc diameter, the RPM of your chosen disc must be compatible with the power tool it'll be used with. Using a disc at a higher RPM for which it's intended can risk serious accidents
We want to make it easy for you to find the right product for you, so we've outlined a common standard for abrasive discs to help you to better understand their applications.
What does ISO 21951:2001 mean?
This standard applies to coated abrasive discs with dust extraction holes. It outlines the testing performed on these types of discs, analysing the grain size and its impact on the distribution of dust during sanding.
Let's break it down...
• ISO - This standard is outlined and published by the International Organization for Standardization
• 21951 - This is the legislation number
• 2001 - This is the year this standard was published
What's the difference between bonded and coated abrasives?
The method used to apply the abrasive grains to the surface of a product is what makes these types of abrasive products different to one another. Coated abrasives are stuck to the surface of the disc, while bonded abrasives feature a combination of abrasive grains and bonding material applied to the disc and left to cure.
Can I use a cutting disc for grinding?
There isn't one disc that covers both of these applications, and for safety's sake, we strongly recommend that you only use cutting discs for cutting and grinding discs for grinding.
