Sanding Discs for Orbital & Random Orbital Sanders
Sanding discs are coated abrasives used with compatible sanding machines for preparing, smoothing and finishing surfaces. Oz Abrasives supplies multiple sanding-disc formats, including hook-and-loop/Velcro, paper, film, foam and mesh options, across a wide range of sizes and grits.
Hook & Loop / Velcro Sanding Discs
Hook-and-loop sanding discs use a reusable attachment system designed to make disc changes straightforward on compatible machines. Match the disc diameter and hole pattern to the sander and backing interface.
Paper, Film and Foam Sanding Discs
Paper-backed discs are available across common sanding applications. Film-backed discs can provide a consistent abrasive backing for suitable finishing applications. Foam-backed discs are available where a more conformable sanding format is required. Select the construction according to the product specification and surface/application.
Dust-Free Mesh Sanding Discs
Mesh/net sanding discs use an open backing designed for dust extraction through compatible sanding equipment. Oz Abrasives carries dust-free mesh products from brands including Mirka and Klingspor. Use the specific product and machine documentation to confirm compatibility.
PSA Self-Adhesive Sanding Discs
PSA sanding discs use a pressure-sensitive adhesive backing rather than hook-and-loop attachment. Keep PSA discs as a distinct product family because the mounting method and compatible backing system differ from Velcro discs.
Choosing the Right Sanding Disc Grit
Choose grit according to the material, amount of material removal and required finish. The current Oz category exposes a wide range from coarse grits through very fine grades, including 40, 60, 80, 100, 120, 150, 180, 240, 320, 400, 500, 600, 800, 1000, 1200, 1500 and 2000 where stocked. Exact grit availability varies by product.
Sanding Disc Sizes
The current category exposes sizes including 96mm, 98mm, 125mm, 150mm, 180mm, 200mm, 300mm, 350mm and 406mm, with other specialised formats also present in the catalogue. Match the disc size to the machine and backing pad.
Hole Pattern and Backing Compatibility
Disc diameter alone does not determine compatibility. Check the hole pattern, attachment type and backing interface required by the sander. Products in the catalogue include no-hole, 8-hole and 9-hole formats, as well as other manufacturer-specific patterns.
Sanding Discs for Wood
Sanding discs are used for preparing and finishing timber and wood surfaces. Select the disc backing, grit and machine compatibility according to the surface and desired finish.
Sanding Discs for Paint, Plaster and Composites
The current Oz category describes sanding-disc use across paint, plaster, metals and composites. Choose a product specifically suited to the substrate and application rather than relying only on disc diameter.
Sanding Discs for Metal
Metal sanding applications require a disc whose abrasive and backing are specified for the material. Oz's catalogue includes aluminium oxide, zirconia, ceramic and silicon-carbide-related sanding products across different disc families. Always follow the individual product specification.

Frequently Asked Questions
What are sanding discs used for?
Sanding discs are used for surface preparation, smoothing and finishing on materials such as wood, paint, plaster, metals and composites, subject to the individual product specification.
What is a hook-and-loop sanding disc?
It is a sanding disc with a hook-and-loop/Velcro-style backing that attaches to a compatible backing pad or sander interface.
What sanding disc do I need for my orbital sander?
Match the disc diameter, hole pattern and attachment system to your orbital/random orbital sander. Then select the abrasive type and grit for the material and finish required.
What is the difference between Velcro and PSA sanding discs?
Velcro discs use a hook-and-loop attachment system; PSA discs use a pressure-sensitive adhesive backing. They require different mounting systems.
What grit sanding disc should I use?
Use a coarse grit when more material removal is required and a finer grit when a smoother finish is the priority. The correct choice depends on the material and application.
What size sanding disc do I need?
Use the size specified for your sander/backing pad. Oz stocks multiple sizes including 125mm, 150mm, 180mm, 200mm, 300mm, 350mm and 406mm, plus smaller formats.
What is the difference between 8-hole and 9-hole sanding discs?
They have different hole patterns for dust extraction and backing-pad compatibility. Match the hole pattern to the backing pad or machine.
Can sanding discs be used on metal?
Yes, where the individual abrasive product is specified for the metal and application.
Can sanding discs be used on wood?
Yes. The current category specifically identifies wood as an application; select the appropriate grit and disc construction.
Are mesh sanding discs better for dust extraction?
Mesh/net discs are designed with an open backing to support dust extraction when used with compatible equipment. Actual performance depends on the disc, machine and extraction system.
