Mirka MR 1.25" 5mm Finessing Sander, MROS150
Product Overview
Mirka MR Series 1.25" Finessing Pneumatic Air Sander with 5mm Orbit (MROS150 / ROS150NV) is a compact, professional-grade 1.25" random orbital (ROS) sander engineered for precision finessing and spot repair work. Its small footprint makes it ideal for tight areas, edges, and localized surface correction in automotive, marine, woodworking, and industrial finishing environments.
Weighing under 1 lb and operating at 8,000 RPM, the MROS150 delivers excellent control with minimal operator fatigue. The 5mm (3/16") orbit provides a more aggressive cut compared to Mirka’s 2.5mm gold‑handle version, and the black handle color clearly distinguishes the 5mm model for quick identification in busy shop environments. The quick‑lock backing pad system allows fast pad changes for efficient workflow.
The air motor features Mirka’s advanced molded composite rotor and blade design, offering long-lasting durability and increased resistance to moisture in compressed air systems. This results in a lightweight, strong, and comfortable tool built for daily professional use.
