Mirka Orbit Finishing Sander 3mm Orbit 3" x 4" MR-34

Mirka MR-34 Orbit Finishing Sander – 3mm Orbit, 3 x 4 Inch

The Mirka MR-34 is a compact pneumatic orbit sander designed for detail finishing work in tight spaces and on contoured surfaces where larger random orbital tools are impractical. The 3mm orbital action produces a fine, consistent scratch pattern suitable for final finish sanding before topcoat application. The moisture-resistant housing makes it durable in spray booth environments.

Why Choose the MR-34?

• 3mm orbital action – Fine finishing orbit suitable for the last sanding pass before coating
• 3 x 4 inch pad size – Reaches corners, recessed areas, and contoured surfaces inaccessible to 5 or 6 inch tools
• Lightweight construction – Reduced fatigue during extended detail finishing sessions
• Moisture-resistant housing – Withstands spray booth humidity and solvent vapor exposure
• Pneumatic drive – Low-maintenance air-powered operation with no electronics to service

Ideal Applications

• Detail finish sanding on cabinet doors, drawer faces, and furniture components
• Automotive interior panels and hard-to-reach body areas
• Trim, molding, and complex-profile surface preparation
• Between-coat finish sanding in spray booths
• Marine interior and joinery finishing
