The Flex XC 3401 VRG 6-inch orbital polisher delivers the power needed to level out the hard and dark finishes that give us detailers the most trouble. Get yours today and you won't be disappointed. - Tim Johnson, Shop Tools Reviews

Flex is a German company producing several lines of products, but are most well known for their finishing tools. In today’s case, we’re looking more closely at a Flex Orbital Polisher. This one is found under the model number Flex XC 3401 VRG and is a 6-inch design with a mechanical orbiting action. Being German, Flex seems to hold up to our expectations of innovation and precision. Let’s look more closely.

This Flex Orbital Polisher boasts seven electronic microprocessor functions. Consistent speed remains under control thanks to a tachometer generator. This helps to keep the RPMs up as pressure is applied. There’s a soft start function that helps avoid spraying your chosen product everywhere and burn through on touchy areas. An accelerator trigger switch is really a fancy way of saying it has a variable speed trigger.

From there, you get restart protection in the case of power failure. Since there’s a lock on button for the trigger, it’s really a nice safety feature to avoid the Flex Orbital Polisher doing its best impression of a Tasmanian Devil on your shop floor around the F-150 you just finished up. Overload protection is also built in to avoid frying the motor.

Temperature monitoring really should be a given at this level and is found on board. Finally, a speed selection dial gives you more control over your maximum speed. That’s certainly nice to have considering the lock on button. However, most of us are likely going to crank the dial all the way up and feather the trigger as needed.

The Flex XC 3401’s orbital action works using a direct drive gearing system. It offers 8 millimeters of orbital action to create an even polished surface. To control the polisher, there’s a knob grip on the front. It’s another feature that’s nice to have, but I’ve found that most Pros are likely to remove it, which it’s designed to be.

One other nice feature is the shut-off carbon brushes. This is more of a self-preservation kind of idea that shuts the polisher off in the event the brushes wear down. The first time it works, you may be want to call Flex and find out why it’s not coming on. A quick check of the brushes and a check of the plug and outlet might save a little face before you make that call.

When it comes to deciding if the XC 3401 Flex Orbital Polisher is worth investing in, performance has to be there no matter how good the tool looks on paper. Head over to Shop Tool Reviews, where Tim Johnson has put together a video of Flex at work with Michael Lucas and him in the body shop!
