Dremel 9100-21 Forti-Flex Stationary Flex Shaft Precision Rotary Tool

The Dremel Fortiflex is a powerful tool. Designed for very precise work, the Fortiflex is an ideal tool for any intricate project. It is indispensable for tasks such as woodcarving using burrs and similar detailing tools, jewelry making, delicate stone carving, glass engraving or any project requiring a combination of power and precision.

The Fortiflex consists of a powerful hanging pendant motor, a heavy duty flexible shaft, a precision handpiece and a foot pedal giving variable speed control (0-20.000rpm). This arrangement makes all the power of a large motor available but keeps the motor out of the way. The flexible shaft delivers that power to a neat handpiece. The slim handpiece is easily maneuverable without the weight of the motor or bulk of a full size tool ensuring greater accuracy and less working fatigue. The foot pedal offers speed control, leaving both hands free especially for the most delicate of items.

The Dremel Fortiflex: power meets precision.

Supplied with foot pedal, handpiece, 21 Dremel accessories and handing hook.
