Shop Lee Valley Mirka Iridium 3″ × 4″ 36-Hole Grip Sheets

Iridium is Mirka’s premium paper-backed abrasive for universal sanding. It has a mix of ceramic and aluminum oxide grains on a flexible paper with a coating that resists clogging and reduces pilling. The 36-hole pattern permits highly effective dust extraction.

Available in nine grits. Priced per 3″ × 4″ sheet.

Usable on a 3″ × 4″ orbital sander or hand-sanding pad with a hook facing, they are best used with a platen protector (sold separately), which prevents damage to the platen’s hook facing and further improves airflow to the platen’s dust-collection holes. An optional 0.28″ thick foam interface pad is also available for contoured surfaces (can also be used with a platen protector).

Made in Finland.

A sample pack is offered separately.
