FAQ DREMEL Fortiflex

The Dremel Forti-Flex has a fully adjustable chuck interface (up to 4mm) for accessories and so can fit any current Dremel Multitool accessory of any mandrel size without the use of multiple collets. The Dremel Forti-Flex should not be used with Dremel Trio accessories as these 4.8mm mandrels are too big for the Forti-Flex chuck. Dremel Multi-Max, Engraver and VersaTip/VersaFlame accessories are also not compatible.

No. To lubricate your flexible shaft use regular ball bearing grease. HINT: in order to prolong the life of your tool, make sure that its flexible shaft is regularly greased.

Yes. The flexible shaft and the hand piece become warm during use; therefore, the grease inside becomes more fluid. Make sure that the hand piece is not hanging downwards after use to avoid the grease dripping out.

Replacements of these items can be obtained from your local customer service.
