Mirka Iridium 8-inch Grip Disc
The Mirka Iridium 8-inch Grip disc with 133H hole pattern and 240 grit is designed for machine sanding tasks. It suits professional workshops and serious DIY users who need consistent surface preparation on various materials. The product was first listed by the manufacturer in June 2022.
Grip attachment limits hole alignment
The Grip hook-and-loop fastening requires a backing pad with the matching 133-hole layout for proper dust extraction. If the pad hole count or spacing differs, the disc will not align with the extraction channels. This mismatch reduces dust collection efficiency and can shorten abrasive life.
Check backing pad compatibility before ordering
Verify that your machine uses an 8-inch backing pad drilled for the 133H pattern before purchase. Confirm the sander accepts hook-and-loop discs rather than pressure-sensitive adhesive types. Ensure the tool’s speed rating suits fine-grit finishing work.
