Normal home users frequently use motor drills.
For typical motor drills, it is difficult and somehow dangerous for users to change drill bits, and at professional working sites, workers usually carry many drills attaching various bits on them rather than changing drill bits.
In order to improve this inconvenience, I devised a solution for changing and attaching bits of motor drills.
We can use motor drills easily by changing cartridges loaded with drill bits that fit for each use such as metal, wood, or rock.
