No problem, they can be expensive, so I generally keep a 2 flute carbide endmill that's a little worse for wear for trying to plunge thru hard materials. Without a drill point though, it can kind of try to shake the machine around a bit if it's not very rigid.

Thanks for the tip of using a hi-roc drill for hard material.
