Product Introduction

Flat-Surface Brilliance, Sustained Through the Hardest Pass

Polishing large flat or gently curved metal panels — automotive body panels, marine hull plating, commercial kitchen equipment — demands a different tool than the contoured belt systems used for round stock. Our high torque cordless metal polisher pairs a dual-action orbital and rotary motion head with a high-stall-torque 20V motor, allowing the operator to maintain consistent polishing pressure across large surface areas without the motor stalling under load, a common failure mode in lower-power cordless polishers when working compound is loaded onto the pad.

The variable speed range of 600 to 3,000 RPM covers the full polishing workflow, from aggressive compound cutting at lower RPM with wool pads to high-speed final glazing with foam finishing pads. A six-position speed lock allows the operator to set and maintain a consistent RPM regardless of trigger pressure variation, critical for achieving an even finish across a large panel where speed inconsistency shows up as visible swirl variation under inspection light. The 180mm pad size matches industry-standard backing plates and polishing pad systems, ensuring compatibility with existing consumable inventories.

Heat management is engineered specifically for sustained polishing duty. The motor housing incorporates additional cooling vents and a larger internal fan than standard angle grinders converted for polishing use, preventing the thermal shutdown that interrupts work on long panel runs. The soft-start function eliminates the sudden torque reaction that can fling polishing compound or mar a freshly painted surface when the trigger is first engaged — a detail that matters significantly to automotive refinish professionals working on customer vehicles.

The extended side handle, positioned for two-hand control during heavy compound cutting, detaches for single-hand operation during lighter glazing passes, adapting the tool's ergonomics to the polishing stage being performed. Battery runtime on the 20V platform supports a full detailing session without a mid-job pack swap. For body shops, marine refinishers, and metal fabrication finishing departments who need dependable, stall-free polishing power without an air compressor or extension cord, this polisher delivers professional, consistent results panel after panel.

Frequently Asked Questions
Q: Does it stall under heavy compound load?
A: No, the high-torque motor is specifically designed to resist stalling that occurs with lower-power cordless polishers.
Q: What pad size does it use?
A: A standard 180mm pad on an M14 spindle thread, compatible with most professional polishing pad brands.
Q: Can I lock the speed setting?
A: Yes, a six-position speed lock maintains a fixed RPM regardless of trigger pressure variation.
Q: Is it suitable for automotive paint work?
A: Yes, the soft-start and consistent speed lock make it well suited for professional paint correction work.
Q: What is the speed range?
A: 600 to 3,000 RPM, covering aggressive compound cutting through fine glaze finishing.
Q: Does the handle detach?
A: Yes, the side handle can be removed for single-hand control during lighter finishing passes.
Q: How does it handle heat buildup?
A: An enhanced cooling vent and larger internal fan prevent thermal shutdown during extended continuous use.
Q: Can it be used on fiberglass and gelcoat?
A: Yes, the variable speed range and dual-action head are well suited for marine gelcoat restoration.
Q: What battery platform does it use?
A: The 20V Li-Ion platform, shared across our professional cordless tool range.
Q: What is the warranty?
A: 1-year professional warranty covering the motor, speed control electronics, and gearhead.
