Manual single speed drill DR-003, very easy to use, and is supplied with two collets of different diameter; one in the cartridge, and the second separately. When you want to install a big drill, it is necessary to find the appropriate collet. Although you can store it directly in the handle – enough to replace the stopper, and the collet insert inside.
