Mirka Iridium HS 9" x 11" Sanding Sheets, 24-101 Series

Product Overview

Mirka Iridium HS Heavy Sanding 9" x 11" Sheets (24‑101 Series) are premium high‑performance hand sanding sheets engineered for fast cutting, long life, and consistent surface quality across wood, putty, paint, solid surface, composites, and lacquers. Iridium HS combines Mirka’s advanced abrasive technology with a flexible latex C‑paper backing for exceptional control on profiles, edges, and detailed surfaces.

Iridium HS uses a premium ceramic and aluminum oxide grain blend — described by Mirka as “premium ceramic and aluminum oxide grain blend for fast, efficient cutting” — delivering aggressive initial cut and maintaining sharpness throughout the sanding process. A dust‑repellent precision coating “reduces clogging and pilling,” ensuring cleaner sanding, longer sheet life, and a more consistent scratch pattern.

Designed for demanding professional use, Iridium HS is ideal for stock removal, paint removal, intermediate sanding, surface leveling, and finish preparation. These sheets deliver predictable results on both soft and hard materials, making them one of Mirka’s most versatile hand‑sanding solutions.

SMSDistributors.com Expert Notes

Mirka Iridium HS sheets are engineered for professionals who need speed, durability, and predictable finish quality. The ceramic/aluminum oxide blend provides a noticeably more aggressive initial cut compared to standard aluminum oxide papers, making Iridium HS ideal for stock removal, paint removal, and intermediate sanding.

The dust‑repellent precision coating reduces clogging and pilling and keeps the abrasive cutting clean longer, especially on putty, paint, and solid surface materials. This dramatically improves efficiency and reduces sheet changes.

The flexible latex C‑paper backing makes Iridium HS excellent for profiles, edges, curves, and detailed surfaces, while still maintaining strong grain adhesion even when folded. This balance of flexibility and durability makes Iridium HS one of the most versatile hand‑sanding sheets for woodworking, marine finishing, composite work, and general refinishing.

For shops looking to reduce sanding steps, improve consistency, and increase abrasive life, Iridium HS is one of Mirka’s most advanced and efficient hand‑sanding solutions.
