Precision-Engineered for Optimal Performance
Our 125mm sanding discs are built using high-grade abrasive grains bonded with precision to deliver even wear and consistent finish. The discs come with a hook and loop (Velcro-style) backing, allowing for quick attachment and removal, minimizing downtime between grit changes. The uniform distribution of abrasive material ensures a longer working life, making them a cost-effective choice for frequent use.
For enhanced dust control, many options feature multi-hole configurations that align with standard orbital sander extraction systems. This not only reduces airborne dust for a cleaner working environment but also helps prevent clogging, extending the life of the disc.
Range of Grits for Every Stage of Sanding
Selecting the right grit is essential for achieving the desired surface finish. Our 125mm sanding discs are available in a full spectrum of grits:
- Coarse Grits (P40–P80): Ideal for stripping paint, smoothing out rough timber, or removing rust and heavy imperfections.
- Medium Grits (P100–P180): Great for prepping surfaces before painting or varnishing.
- Fine Grits (P240–P400): Suitable for final finishing, between coats sanding, or polishing tasks.
Each grit category is color-coded and clearly labeled for quick identification, saving you time during busy jobs.
Compatible with Leading Orbital Sanders
All discs are manufactured to fit standard 125mm orbital sanders. Thanks to their universal backing system and multiple hole designs, they are compatible with machines from brands like Bosch, Makita, DeWalt, Festool, and more. Whether you're using a 5-inch orbital sander at home or in a professional workshop, these discs are engineered to deliver maximum efficiency.
Applications of 125mm Sanding Discs
These sanding discs are incredibly versatile and are widely used in a variety of industries:
- Woodworking: Smooth out surfaces, remove rough grain, and prepare wood for paint or varnish.
- Metalworking: Remove surface oxidation, weld splatter, or prep for coating applications.
- Automotive Refinishing: Strip old paint, feather edges, and prep body panels for repair or respray.
- Construction & Drywall: Perfect for finishing plasterboard joints or smoothing down filler before decorating.
