For the lazy :-)

Replaces the tip of the Dremel which is tightened with the collet.
Very easy to use, and then quenched greenhouse / loosens very easily by hand, without using the clamp.
Disadvantage compared to conventional nut:
- 3 jaws to hold only the tip (strawberry, drill, etc.) while the classic nut screw covers a support 4 jaws. We must therefore tighten to hold it despite the significant rotation of the tool.
Advantage:
- No need to clamp
- No need to change it even if we radically change in diameter to the tip (with the classic nut unscrew and changing media).
