Keyless chucks

Quick-clamping

— a chuck that can be opened and closed without the use of special tools. This makes changing drills as simple and fast as possible: you do not need to take the key every time, which, moreover, can be lost. At the same time, it is believed that keyless chucks are inferior to key chucks in terms of fastening reliability, and also endure heavy loads worse. Therefore, it makes sense to use them in cases where work is planned with frequent replacement of drills and without heavy loads.
