⚡ At a Glance
- • Polishing Performance: 500W motor with 2,000–4,200 rpm and a 21mm hub for high surface speed
- • Best for: Professional detailers and experienced DIY users needing mid-weight orbital correction
- • Not ideal for: Beginners seeking an ultra-light or very low-power polishing tool
A 500W motor drives an eccentric head across a 2,000–4,200 rpm range with a 21mm hub and 150mm backing plate. Electronic speed control, anti-twist collar and on/off lock support secure, sustained polishing.
Faster defect removal – thanks to a 500W motor and 2,000–4,200 rpm range
A 500W motor turns the eccentric assembly through a wide rpm band, increasing surface speed for compound and polish work. The 2,000–4,200 rpm range lets the head operate from moderate to aggressive polishing rates.
Higher surface speed helps speed up correction of swirls and oxidation, cutting down time spent on heavy polishing tasks.
Better control and consistency – with electronic speed control and a 21mm hub
Electronic speed control allows precise selection of rpm within the stated range for repeatable work. The 21mm hub generates a defined orbit that produces predictable polishing behaviour across panels.
Fine-tuning speed and a consistent orbit make it easier to match pad and compound choices to paint hardness, reducing the need for retouches.
Safe, workshop-ready handling – with anti-twist collar, on/off lock and M8 connection
Anti-twist protective collar helps prevent accidental pad rotation, while an on/off lock secures continuous runs. The M8 connection provides a standard interface for secure accessory mounting.
Secure pad mounting and protective features reduce the chance of slippage and make longer polishing sessions more comfortable and dependable.
