Polisher types compared: dual-action, long-throw, rotary and more
Pick a polisher type to see how it moves, which pad sizes and throws it uses, and the jobs it suits or should avoid.
Choose your polisher type to see the key facts. Each one links to its source on the full page.
All polisher types
- Free-spinning dual-action (random orbital) polishers On a free-spinning random orbital polisher the plate orbits and rotates freely, so rotation can slow or stop under friction. Throws, plates and limits.
- Forced-rotation (gear-driven) dual-action polishers A forced-rotation polisher's plate orbits and is geared to rotate, which RUPES calls more aggressive with more vibration. Throws, speeds and models.
- Rotary polishers A rotary polisher spins on one axis with no orbit. Auto Care HQ says heat and friction build faster and that rotaries are mostly for experienced users.
- Short-throw dual-action polishers (5-12 mm) Short-throw machines use a 5-12 mm orbit: RUPES LK900E 5 mm, Makita XOP02Z 7/32 in, SPTA CP501 9 or 12 mm and RUPES HLR75 12 mm.
- 15 mm long-throw polishers (5-inch class) 15 mm random orbital polishers usually run a 125 mm (5 in) plate: RUPES LHR15ES, Milwaukee 2684-20, FLEX XFE 15. Speeds, plates and limits.
- 21 mm long-throw polishers (6-inch class) 21 mm random orbital polishers pair with 150 mm (6 in) plates, like Milwaukee's 2685-20. What the bigger orbit is said to suit and what to check.
- Mini polishers (3-inch class) Mini polishers like the RUPES HLR75 use a 75 mm (3 in) plate and 12 mm orbit for curves and compact areas. Battery, runtime and charger notes.
- Multi-mode micro polishers FLEX's 12V PXE 80 set swaps between a rotary head and 3 mm or 12 mm orbital heads, with 30 mm and 75 mm plates. What the US kit includes.
- Corded polishers Corded polishers need a supply voltage that matches your outlet and a certification mark on the tool. What makers state, and the GFCI rule.
- Cordless polishers Cordless polishers run on closed battery platforms: Milwaukee M18, Makita 18V LXT, FLEX and RUPES iBrid. Why the same voltage is not the same pack.
