Porter Cable Buffer

The 7424 Dual Action Orbital Polisher

The 7424 Porter Cable buffer is a dual action random orbital polisher.

Dual action random orbit simply means that the head of the tool spins on two separate ax'es (and yes that is plural for axis...I even looked it up).

Porter Cable Buffer

What that means for the user is that you have less chance to make swirl marks on the finish of what you are polishing.

With variable speed settings between 2,500 and 6,000 OPM (Oscillations Per Minute) this unit has the power and speed to bring the very best shine to any old surface.

From the old car to the dull boat this buffer really shines.

Porter Cable BufferProsCons
  • Plenty of power
  • Plenty of speed
