Mirka MR-30 3-in. Pneumatic Rotary Polisher for Small Area Finishing (MR-30)

Mirka MR-30 Palm Buffer Non-Vac is a compact pneumatic rotary polisher built for small-area finish correction and detail polishing. This is a rotary polisher designed for spot repair, paint rectification, and headlight restoration. Model Number: MR-30. If you do topcoat correction, clearcoat polishing, or denibbing in tight spaces, this tool is built to give you more control than a larger polishing machine.

The 3 inch pad size is the big story here. It lets you work smaller panels, blend areas, and localized defects without dragging a large backing pad across surrounding paint. For body shop work, that means better access around edges, tighter sections, and repair zones where precision matters more than raw coverage. Mirka also rates the tool at 3,000 RPM with a 0 mm orbit, so you are getting true rotary polishing action for focused correction work.

Because this is a non-vacuum pneumatic polisher, the setup stays simple. There is no dust extraction hardware to manage, and no battery or corded motor to add bulk at the tool body. The work pressure is listed at 6.2 bar, which puts it squarely in the kind of compressed-air workflow many paint and body shops already run every day. If your shop is already set up for air tools, the MR-30 slides right into that system.

Mirka positions the MR-30 for smaller polishing jobs after using its SR products, and also for restoring headlights. That lines up with the tool’s compact footprint and controlled rotary action. It is not trying to replace a full-size polisher for broad panels. It is for the cleanup work, the targeted correction work, and the areas where a big machine becomes awkward or too aggressive to handle comfortably.

The lightweight composite construction matters more than it sounds on paper. A small detail polisher gets used one-handed, at odd angles, and often for repetitive correction passes. A lighter body helps reduce hand fatigue, while the composite design and moisture-resistant rotors are aimed at long service life in shop conditions. Premium bearings and the gear-driven design add to the sense that this tool is meant for repeat professional use, not occasional hobby duty.

Noise and vibration also affect day-to-day comfort. Mirka lists the noise level at 81.0 dB and vibration at 1.4 m/s². On a tool made for close-up polishing and detail work, lower vibration helps you stay smoother on the panel and keep better feel over the pad. That is especially useful when you are working near repaired paint, blending edges, or refining a small defect where too much movement can create more cleanup work.

The Mirka MR-30 Palm Buffer Non-Vac is a good fit for automotive refinish techs, body shops, detailers handling paint correction, and anyone doing focused polishing work on small surfaces. It also makes sense for serious users who want a dedicated small-area polishing tool instead of trying to force a larger machine into places it was never meant to go. If your work is mostly spot repair and precision polishing, this is the kind of specialized tool that saves time and gives you better control.

Mirka MR-30 Palm Buffer Non-Vac is the right kind of niche tool
