The proud price startled me at first but all very down, but since I own this chuck for my Dremel, I am happy to have bought it anyway. Finally I do not have every few minutes if I need the other tool, change the clamping sleeves. For now I turn the chuck on, take out the tool and insert into the other tool and turn to. Quick and easy. What struck me about all only was the filigree workmanship of the drill chuck, because I have to say a top product. I also frequently or often drill with the Dremel and therefore use several small drill, you have with this chuck simply the decisive advantage that the drill always fits (if the drills between 0.8 and 3.2mm diameter possess).
Advantages at a glance: - Spans all tools and drills with diameters between 0.8 and 3.2mm - Tool can even be hand tight enough to attract (no key to switch required) - High quality
Thus, I conclude Conclusion: I highly recommend this chuck without any complaints to anyone who drilled a lot and often replaces the tool. Despite the initially high price you will not be disappointed.
