One action is the circular rotation and the second action is the random movement of the pad while it is rotating. This random oscillation also has a exceptionally "long throw" of 8 mm. The forced circular pad rotation coupled with the long throw of the oscillations give the Flex considerably more cutting power than the Porter Cable 7424. In fact, it will do 90% of what a pure circular polisher can do with the safety of the random oscillations to prevent swirls. This is a real break thru!
The Flex XC3401VRG has a bale-style handle which puts your hands at the 6 o'clock and 12 o'clock position which most professionals prefer. This gives you an even weight distribution between your hands, making the polisher less fatiguing when used for long periods. A six position speed control allows you to limit rpm's between 160 rpm and 480 rpm. Under the speed control, a variable speed trigger allows you to feather the oscillations per minute (OPM's) up to the maximum set by the speed dial. A very nice touch for keeping the rpm's low for applying waxes and sealants which you normally can not apply with a circular polisher.
Since the Flex XC3401VRG has a forced circular motion, every speed setting is slightly more powerful when compared to the Porter Cable 7424. If you are stepping up from a 7424, we recommend starting one speed setting lower than you would with the 7424. In other words, If you typically polish in a speed range of 3 to 4 with the 7424, start with a speed range of 2-3 with the Flex. You can always increase the speed if you need more cutting power.
This machine has a very solid "feel", like it could operate all day without stopping. It never feels strained or "near the edge". Feature wise, the Flex XC3401VGR is one of the most technologically advanced machines on the planet. It features a seven function microprocessor to insure consistent speed, restart protection after power interruption, overload protection and temperature monitoring. Auto shut-off carbon brushes automatically shut off the motor when they wear down to prevent motor damage. A 10 foot power cord allows you to work around most vehicles and the machine comes with a one year warranty through service centers across the US.
The Flex comes with a 5.5" padded backing plate that will accommodate our 6.5" pads.
