Tiêu đề Chuck chèn Tóm tắt Để lấy đường kính lớn hơn 13m

I use it when I have to frost small tubes that the manual drill chuck cannot grip. For the screw I inserted a hot M4 bushing. I added 3 models to take tubes up to diameter 20.

It can be used to carry drill bits for wood, just turn hard and don't push, for metals, even non-ferrous ones, I wouldn't recommend it.
