Our take on the Porter-Cable 7424XP Variable Speed Random Orbit Polisher

The Porter-Cable 7424XP is a corded 6-inch random orbit polisher with a 4.5 amp motor and a variable-speed dial from 2,500 to 6,800 orbits per minute. It handles polishing, waxing and sanding on paint, wood, metal and gelcoat, and its 5.5 lb body and removable two-position side handle keep it manageable for long sessions. The best new price is $144.00 at eBay as of November 5, 2026, with 7 stores listing it new. That sits at the low end of what this model has sold for recently, so it is a fair time to buy.

Cons

Questions and answers

Is the Porter-Cable 7424XP worth it?
For a corded 6-inch DA polisher, yes. It covers compounding, polishing and waxing with a proven motor, and at $144.00 at eBay as of November 5, 2026 it is priced at the low end of its recent range.
How does it compare with the 7424XP's predecessor, the 7424?
The XP adds a more powerful 4.5 amp motor and a wider 2,500-6,800 OPM speed range. The body and pad size are essentially the same, so pads and backing plates carry over.
What pads and accessories fit it?
It uses a 6-inch pad and takes 5/16-24 spindle accessories, so most DA backing plates and pads fit. The box includes a polishing pad, side handle and wrench.
Can it sand as well as polish?
Yes. The random orbit motion works for sanding and finishing wood, though the 6-inch pad is large for detail work. Use lower speeds for sanding and higher for compounding.
Does it come with a case or extra pads?
No case. You get the polisher, one polishing pad, a removable side handle and a wrench. Budget for extra pads and a backing plate if you plan to compound and polish.
When is the best time to buy it?
Prices hover near $144 to $160 across the 7 stores listing it new. Watch for holiday and spring detailing sales, when corded polishers typically dip.
