Drills with keyless chuck
Quick-clamping
— a drill chuck in which no special tools are required to change the nozzle — just a manual effort. Such cartridges are much more convenient than key cartridges: you do not need to use the key every time, which, moreover, can be lost. However the reliability of holding a drill in a keyless chuck is somewhat lower than in a key one; however, this becomes critical only at the highest loads, or during long-term work with a heavy load, for other cases, the reliability of such clamps is quite sufficient.Show
