Mirka 5" 2.5mm Non-Vacuum Sander, MR-525
Product Overview
Mirka MR‑525 5" Finishing 2.5mm Non‑Vacuum Pneumatic Air Random Orbit Sander (ROS) is a professional‑grade finishing tool designed for high‑quality surface preparation in automotive, marine, woodworking, and industrial environments. The 2.5mm (3/32") orbit delivers exceptionally fine finishing results with minimal swirl marks, making it ideal for final sanding and refined surface work.
Constructed from precision‑molded composite materials, the MR‑525 offers excellent strength, durability, and reduced operator fatigue. Its ergonomic design minimizes vibration and sound levels, improving comfort during extended use. Moisture‑resistant composite rotors and premium counterweight bearings ensure long service life and reliable performance.
Delivering true 12,000 RPM performance, the MR‑525 is counter‑balanced specifically for its 5" backup pad (110‑gram weight), providing smooth operation and consistent finishing quality.
This sander can be converted to a vacuum‑ready or self‑generating vacuum configuration using optional conversion kits (sold separately), offering flexibility for dust‑free sanding setups.
Includes pad wrench, air‑tool oil, and a 5" vinyl‑face backup pad compatible with PSA sticky‑back sandpaper.
