There is a transparent protective cover around its drill bit, which can not only stabilize the fuselage and vertical working plane, but also prevent droplets from splashing on the bottom of the fuselage when looking up. There are pressure control switches and auxiliary depth measuring devices. Press the switch at the bottom of the fuselage by hand. The harder you press, the faster the speed, this special operation method can effectively avoid the sudden start of the motor and lose control, and the auxiliary depth measurement device can facilitate the user to control the depth of the hole more accurately

The plane to be drilled is smaller than the cover ring, or if you need to drill a hole with a non-vertical angle, you have to take out the traditional drill.
I think it is better if the structure at the bottle mouth is inclined, otherwise the sawdust will show a little when you take it.
Power tools?
Wow! This is good.
