This test was made to check the behavior of a drill to get familiar with the process and consider it for machine structure requirements.

Materials:

1. Drill:
- Brand and model: Bosch GSR 18V-21
- Torque: 21/55Nm

2. Bit:
- Diameter: 32mm
- Length: 500mm

Process:

The first time, I got to drill 30cm depth.

The second time, I got to drill 50cm, which is the total length of the bit.

Results: From this test, I observed that it can not take the soil sample by drilling in one go, separate the total depth on multiple phases would be the best in this case.
