For DIY enthusiasts who want to keep their bits handy while screwing, Bosch now offers the PSR Select. This cordless screwdriver features an integrated drum that contains twelve standard bits. To change bits, simply rotate the drum until the desired bit appears in the viewing window, then push it forward into the bit holder using the switch located behind the drum, and you can work as usual. With this "Easy Select" system, no bit will be lost, and you can save time searching for the right accessory. If a bit needs to be replaced, just remove it from the bit holder, replace it with a new one, and then pull it into the drum using the switch. The selection can be easily customized to meet your needs.
