Has anyone used the auto quill feed for drilling in hard material, like 4140 or 304 stainless? Is the macihine designed for this or will it wreck the head?

Thanks.

I don't think it was designed to drill holes, used mostly for boring holes.

It has been described as being able to drill a 3/8 inch hole in mild steel. It exerts a force of about 200 pounds.

Why would you want to use a quill feed to drill a hole? You can't be that lazy.
