Dremel 9100 vs Foredom

Features of the Dremel 9100

The Dremel 9100 is a high-precision rotary power tool with a flexible shaft. It can generate up to 23,000 RPM thanks to its powerful 120 volts, 2.5 amp motor. The 9100 works the same way as a pen, with varying speeds regulated by a simple foot pedal. The foot pedal speed control feature frees up your hand, allowing you to focus entirely on gripping the power tool as securely as possible. Those who can drive will discover that using the foot pedal comes naturally. It may take some time for persons who do not or cannot move to become acclimated to the foot pedal.

The Dremel FortiFlex 9100 is ideal for woodworking, while it may be essential for various activities. And this may help you make those finely detailed minor cuts, add texture, and sand your work to make it pop.

Any of Dremel’s rotary tool accessories and any of their other accouterments with a size ranging from 0 to 5 inches are compatible with this model. You can swap the handpiece of this powerful tool for any other Dremel FortiFlex hand component. The 9100 comes with a two-year comprehensive warranty, which means that any defects identified during that time will be fixed free of charge by Dremel.


  • Using the foot pedal frees up your hand.
  • You can employ it in a wide range of situations.
  • It is compatible with all additional Dremel rotary tool attachments.


  • Poor build quality

Features of the Foredom

This particular kind is prevalent among jewelers. And this is due to its 1.6-horsepower hang-up style motor, which can spin at 18,000 RPM (in both reverse and forward rotation). And this is a feature that any left-handed individual will appreciate. The motor of the Foredom is mighty, and it came to improve the overall performance of the power tool. It has the added strength required for long-term use in the demanding jewelry manufacturing process.

The Foredom speed gets controlled by a foot pedal with elevated electronics housed in a sturdy black plastic enclosure. Those who do not drive may find it challenging to use the foot pedal at first, like with the Dremel. On the other hand, the majority of users rapidly pick up on this feature.

It has a three-jaw geared chuck with a 0 to 5-inch capacity. And this means it can accommodate a mandrel with a diameter of up to 5 inches. A chuck key is incorporated for tool changes, making the operation easier. The foot pedal and motor have a two-year limited warranty; however, the handpiece has just a 90-day warranty, which implies that any problems identified with these parts will be corrected free of charge by Foredom.


  • Good for left-handers
  • Increased productivity


  • The motor has limited capacity

Price comparison

The Foredom is costlier than the Dremel 9100. The Foredom 2230 Flexible Shaft Rotary Tool is the ideal tool for anyone looking for a tool that will stay on their bench and deliver a professional experience at an affordable price. You can’t go wrong with a Dremel tool because of the enormous number of accessories available, even if your budget is limited.


Foredom appears to be better designed than slavery (but the Dremel is still a high-quality flex shaft tool). The Dremel is the most similar to the Foredom, but its maximum speed is faster. Although it’s still of good quality, Foredom appears to make a more lasting and well-engineered instrument. 

The Dremel 9100 Fortiflex is compatible with Dremel attachments. The Foredom has more power, is more specialized, and has a more extensive selection of kits for specific applications such as wood carving and jewelry making. They all have more accessories than the Dremel 9100 kit, with only 21.

The Foredom can go forward or backward in time. Some of the benefits of running in reverse are as follows:

  • Left-handed users have greater control over the cutting device.
  • By employing reverse, dust and other particles are kept far away from right-handed users.
  • Changing motor orientations can make some abrasives last longer.
  • Use reverse grinding and carving procedures to obtain symmetrical results.
  • The reverse makes it easier to remove stuck drill bits.
  • When altering the motor direction, polishing metals becomes more accessible and faster.

The end speed of a Dremel is higher than that of a Foredom – 23,000 RPM vs 18,000 RPM. The Dremel comes with 21 attachments, including carving/engraving cutters, grinding stones, a Cleaning/ Polishing Brush Wheel, sanding bands and models, and a drill bit set. This tool is compatible with Dremel accessories and attachments.

Use comparison

Foredom is the best choice for any large-scale precision task. Wood carving, general application, and jeweler kits are all popular. It’s better for more demanding activities like hogging vast quantities of wood or porting engines. Foredom is an excellent choice for users who want more power from their flex shaft tool. 

The Dremel 9100 is suitable for hobbies like wood carving, jewelry making, engraving, and more that require precision. It’s designed for power carving, sculpting, and grinding, among other things. However, if you have attachments for other jobs, it can do it. It’s a tool with a lot of torque but only a little speed.


The Dremel 9100 comes with a two-year comprehensive warranty, which means that any problems identified during that time will be repaired free of charge by Dremel. The foot pedal and motor of the Foredom have a two-year limited warranty; however, the handpiece has just a 90-day warranty, which means that any defects identified with these parts are corrected free of charge by Foredom.


The Dremel is heavier and prone to “torque steering,” or spinning in your hand. The Foredom appears to be more comfortable to hold in the hand because it is lighter. A Dremel flex shaft is more potent than a Foredom flex shaft powered by a rotary motor. Because a hand crank is valuable to operate a Foredom flex shaft, it isn’t as strong as a motorized flex shaft and isn’t ideal for heavy-duty applications.


We suggest the Dremel FortiFlex 9100 for purchase after thoroughly researching both power tools. And this is due to its increased power and usefulness in various sectors, such as jewelry making and carpentry. However, the Foredom is still a good power tool, and many people would be happy with it, so don’t give up if you already own one.
