Bosch 12V Max Brushless 3 Inch Cordless Random Orbital Polisher GPX12V-77N Bare Tool

The Bosch GPX12V-77N 12V Max Brushless 3-Inch Cordless Random Orbital Polisher operates as a commercial-grade automotive refinishing and spot-repair power tool engineered to blend clear coats, remove scratches, and buff localized oxidation on tight vehicle panels. Powered by a high-efficiency brushless motor delivering variable speeds from 600 to 2,200 RPM across 5 electronic speed settings, this 12V dual-action buffer features a 3-inch hook-and-loop backing pad, a digital handle interface, a trigger lock-on button, and a net bare tool weight of 1.7 pounds. Compatible with Bosch 12V Max lithium-ion batteries, this compact detailing polisher incorporates a rear non-marring rubber resting pad to prevent paint scratches when set down on workbenches.

**Battery and charger sold separately.**

Best Used For:

  • Automotive Clear Coat & Paint Scratch Spot Repair: Buffing out localized paint defects, wet sanding marks, and deep scratches on isolated vehicle panel areas.
  • Tight Contoured Panel & Bumper Detailing: Navigating narrow door pillars, mirror caps, front grilles, and complex bumper curves using the compact 3-inch pad footprint.
  • Mobile Collision Repair & Clear Coat Blending: Polishing fresh clear coat transitions and feathering paint repairs in body shops without cumbersome air lines or extension cords.

Key Performance & Safety Features

  • High-Efficiency 2,200 RPM Brushless Motor: Advanced brushless motor supplies continuous rotational torque and speed stability under pad pressure for fast material removal.
  • Digital Smart User Interface Console: Handle-mounted digital screen provides push-button access to 5 electronic speed presets, battery fuel level readings, and timed auto-shutoff settings.
  • Ultra-Compact 3-Inch Pad Footprint: Micro 3-inch backing disk geometry allows operators to target tight trim areas and complex vehicle contours with surgical accuracy.
  • Continuous Run Lock-On Thumb Button: Side-mounted lock-on switch holds trigger engagement to eliminate finger strain during prolonged polishing passes.
  • Protective Non-Marring Rear Rubber Pad: Rear-mounted rubber bump pad stabilizes the tool horizontally when resting to prevent accidental contact between the head and fresh paint.

Pro-Tip: When performing clear coat spot repairs on curved bumpers or narrow body pillars, keep the 3-inch foam pad completely flat against the paint surface and set the speed dial to setting 2 or 3 (1,200–1,500 RPM). Tilting the polisher on its edge concentrates friction heat on a tiny area, which can quickly burn through thin automotive clear coats.
