The Mirka MR-510TH-G is a 5 in. two-handed pneumatic finish sander engineered for industrial sanding applications requiring high material removal rates and dependable surface preparation. Featuring a 10mm orbit pattern paired with a true 12,000 RPM pneumatic motor, this finish sander provides high-speed efficiency across woodworking, composite fabrication, and general metalworking operations.

Constructed with precision molded composites, the MR-Series body delivers high strength and durability while keeping overall tool weight low. The lightweight composite construction and balanced counterweight design dampen operating noise and vibration, significantly reducing operator fatigue during long sanding shifts. Moisture-resistant composite rotors and premium counterweight bearings ensure long service life and high reliability in demanding pneumatic shop environments.

This model is specifically configured with both grip (hook-and-loop) and PSA (pressure-sensitive adhesive) backing pads, giving operators the flexibility to use either abrasive style without purchasing additional hardware. Configured 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.
