The Mirka MR-6-G is a 6 in. pneumatic finishing sander engineered for industrial surface preparation and fine finishing tasks across woodworking, composite fabrication, and automotive refinishing applications. Featuring a 5mm orbit paired with a true 12,000 RPM pneumatic motor, this finishing sander delivers smooth stock removal and consistent surface quality during continuous operation.

Constructed with precision molded composite housing, the MR-Series body provides high durability while keeping overall tool weight low. The lightweight composite structure and balanced counterweight design minimize vibration and operating sound, reducing operator fatigue during long sanding sessions. Moisture-resistant composite rotors and premium counterweight bearings protect internal components and deliver long service life in high-demand shop environments.

This model includes both grip (hook-and-loop) and PSA (pressure-sensitive adhesive) backing pads, allowing operators to switch between abrasive attachment types without purchasing additional components. Built as a non-vacuum unit out of the box, the tool can easily be converted to vacuum dust extraction by adding an optional external or self-generating vacuum adapter.
