IRIDIUM DISCS 125 MM GRIP 89A

What is Mirka Iridium Discs 125 mm Grip 89A and why choose it

Mirka Iridium Discs 125 mm Grip 89A are high-performance coated abrasive discs designed for fast, efficient sanding of both soft and hard surfaces. Manufactured with cutting edge technology, these grey sanding discs combine ceramic and aluminium oxide grains on a flexible latex C-paper backing. The result is a disc that cuts quickly, resists clogging and stays sharp longer, helping you move from rough to smooth finishes in fewer steps.

With a convenient grip (hook and loop) attachment and an advanced multihole pattern for effective dust extraction, Iridium 125 mm discs are ideal for professional use in automotive refinishing, woodworking, composites, marine work and construction and decoration tasks.

Main features

• Fast cutting action thanks to premium ceramic/aluminium oxide grain that removes material quickly.
• Long-lasting sharpness – precision coating practically repels dust so the abrasive grains stay sharp for longer use.
• Fine surface finish with fewer sanding steps, from rough stock removal to smooth finishing.
• Effective dust extraction via Mirka’s multihole pattern, designed to minimise clogging and improve working comfort.
• Durable, flexible backing using latex C-paper that offers good grain adhesion and conforms well to curves and contours.
• Wide grit range (from coarse to very fine) to cover all stages of sanding in one compatible system.
• Easy attachment with grip backing for quick disc changes on compatible 125 mm sanding machines.
• Versatile use on different materials, from automotive paints to wood, composites and many other surfaces.

FAQ – Mirka Iridium Discs 125 mm Grip 89A

1. What materials can I sand with Mirka Iridium 125 mm discs?

   These coated abrasive discs are suitable for many materials, including automotive paints and primers, various wood types, composites, marine coatings and surfaces used in construction and decoration.

2. What is the advantage of the ceramic/aluminium oxide grain blend?

   The combination of ceramic and aluminium oxide grains delivers aggressive cutting with high durability. The grains maintain sharpness longer, which improves productivity and reduces disc changes.

3. How does the multihole pattern improve sanding performance?

   The multihole pattern optimises dust extraction across the disc surface. Better dust removal keeps the abrasive cutting edges exposed, reduces clogging and contributes to a cleaner working environment.

4. Which machines are compatible with these discs?

   Mirka Iridium 125 mm Grip 89A discs are designed for use on 125 mm sanding machines with a grip (hook and loop) backing pad and suitable dust extraction.

5. Are these discs suitable for both coarse and fine sanding?

   Yes. The Iridium range covers grits from 40 to 1000, allowing you to use the same disc family for coarse sanding, intermediate steps and final finishing, depending on the grit selected.

6. Do the discs contain any hazardous substances?

   The coated abrasives are considered articles and are not classified as dangerous substances or mixtures under Regulation (EC) No. 1272/2008. Normal handling and use, as intended, do not present specific chemical hazards.

7. How should used discs be disposed of?

   Disposal as non-hazardous waste is generally possible if no hazardous materials have been added during use. Always follow current national and regional waste regulations.

8. How should the discs be stored?

   Store the discs according to the sanding machine and abrasive manufacturer’s recommendations, in a dry area and away from extreme temperatures, to maintain performance and stability.

9. Do I need special first aid measures when using these discs?

   No specific first aid measures are required for the discs themselves. If irritation from dust occurs, follow general first aid practices and consult a physician if necessary.

Section 14 – Transport information

The product is not covered by international regulations on the transport of dangerous goods.

Section 8 – Individual protective measures

Before sanding, it is recommended to carry out a risk assessment and select personal protective equipment according to the specific application and the material being ground. Dust from the workpiece can be hazardous; observe applicable national exposure limits for dust and local safety requirements.

• Respiratory protection: Use suitable respiratory protective equipment when dust cannot be adequately controlled by extraction.
• Hand protection: Wear appropriate protective gloves.
• Eye and face protection: Use safety goggles or a face shield to protect against airborne particles.
• Hearing protection: Wear suitable hearing protection when working with power-driven sanding machines.
• Body protection: Use protective clothing appropriate to the task to protect skin and personal garments from dust and debris.
