ADBL Roller D21 v2 – 21mm Dual Action Polishing Machine

Big throw. Big power. Serious paint correction.

The ADBL Roller D21 v2 is a 21mm long-throw dual action polisher built for one thing — covering large panels fast and leaving nothing behind but gloss. With a huge 21mm orbit and an 810W motor, this DA polishing machine chews through swirl marks, light scratches and oxidation in a fraction of the time of a short-throw machine, while the dual action movement keeps the process safe on your paint. No holograms. No burn-through fear. Just results.

Why a 21mm dual action polisher?

Throw is everything in machine polishing. The D21 v2's 21mm stroke moves the pad across a far wider path with every orbit, so each pass covers more paint and corrects faster. That makes it the ideal machine polisher for bonnets, roofs, doors and vans — anywhere you need maximum coverage. Paired with a finishing pad and polish, it also finishes down beautifully, so one machine handles cutting and refining.

Power that doesn't fade

The 810W motor delivers speeds from 1,650 to 4,500 OPM with electronic speed stabilisation — press the pad into the panel and the machine holds its speed instead of bogging down. The soft-start system spins up smoothly with no polish sling, and the ergonomic low-profile head keeps you comfortable through a full correction detail. The generous 8-metre cable means you'll walk around the whole car without hunting for an extension lead.

Built for real detailing

The D21 v2 ships with a 125mm (5") backing plate and also accepts a 150mm (6") plate, so it slots straight into your existing pad collection — including our Blade Performance 5" heavy cut, medium cut, light cut and finishing pads. Add a quality compound and you've got a complete paint correction setup.
