Mirka Iridium 8" Grip 133H 120 Part
The Mirka Iridium 8" Grip 133H 120 part is a new abrasive disc designed for machine sanding applications. It suits professional technicians and workshop operators who require consistent surface preparation on automotive or industrial substrates. The 8-inch diameter fits compatible random orbital sanders used in refinishing workflows.
Grip Attachment and Hole Configuration
The 133-hole pattern aligns with multi-hole backing pads to optimise dust extraction during operation. A grip-style fastening allows quick disc changes without adhesive residue on the backing pad. The 120-grit rating provides intermediate material removal suited for levelling primer or preparing for topcoat application.
Installation and Common Issues
Press the disc firmly onto a clean 8-inch grip pad ensuring hole alignment with the pad's extraction channels. Misaligned holes reduce vacuum efficiency and can cause premature edge wear. Contaminated pad surfaces weaken grip adhesion leading to disc slippage under load. Replace worn backing pads to maintain flat contact across the full 133-hole array.

Questions about this item
How often should the 133H abrasive disc be replaced during heavy sanding?
The 133-hole pattern on the 120-grit Iridium disc promotes dust extraction, extending disc life; replace when cutting performance drops noticeably.
What limits continuous sanding time with this 8-inch grip disc?
Heat buildup on the workpiece surface typically limits session length before the 120-grit abrasive glazes or the backing overheats.
Does the 133H disc generate less noise and dust during all-day operation?
The 133-hole design improves airflow, reducing airborne dust and lowering the sanding roar compared with fewer-hole discs.
