The small mill drill I have I was able to eliminate the vibration and the torque of head.

Re: Mini-mill vs. Mill-drill?

Re: Mini-mill vs. Mill-drill?

Re: Lathe Front Shields
That is very true.
Just stand to one side and let the oil fly.

They come in different shapes. This kind has a hole for an M3 size screw.
