Dremel Fortiflex Flex Shaft Tool – Review

Dremel Fortiflex Heavy Duty Flex Shaft Tool

As a prop maker, I deal with a lot of fiberglass and rubber castings. Some are more detailed than others, but the bottom line is that I have to make them look as good for the camera as possible. This takes a lot of time and patience. I was thrilled when Tool Skool asked me to test out the Dremel Fortiflex, because my go-to tool of choice for most jobs is a rotary tool. With the newest design features, it sounded like I’d be able to save some time and some wrist aggravation.

When I create prop replicas, there’s sometimes a lot of detail that needs to get done – on a deadline.

The Fortiflex gave me a lot of flexibility (pun intended) when it came to get into tight spots on the helmets I was making.

Take a look at my first video tool review below, and then read on for more information on this pretty awesome tool.

What’s the Difference?

If you’ve used a rotary tool, you understand that they can get a little heavy after extended periods of sanding or cutting. Plus, there’s the constant switching ON and OFF, FASTER and SLOWER speeds, etc. Not that it’s akin to moving large rocks all day long, but it does tend to get a bit tedious.

The Fortiflex hand piece (left) is lighter and thinner than a standard rotary tool, because the motor and other components are housed separately.

With the Fortiflex, you simply depress the pedal and the tool springs to life. Press the pedal harder, and the tool spins faster. It really does remind me of driving a sports car – you can feel the precision in the tool. The hand piece is lighter and thinner than a standard rotary tool, as well. It’s more like holding a large pen, and gave me the ability to move it around my work more accurately.

By depressing the foot pedal on the Fortiflex, you control the speed of the tool.

Another great feature of the Dremel Fortiflex is the 3 jaw chuck. Again, unlike standard tools in the genre which have different-sized collets that need changing out to accommodate different shaft diameters of accessories.

The 3 jaw chuck allows you to use accessories with diameters from 0 – 5/32 of an inch.

Accessories store neatly in the base of the stand, which in turn clamps to any work surface up to about 1 3/4 inches thick.

Fortiflex Findings

Here’s my opinion – it’s a great tool, but it also comes with a decent price tag. While it may seem expensive on the surface, you’re getting a lot of value for the money, especially if you use this in any sort of money-making venture. There’s no doubt it will save you time – it did me.
