Bore hole drills-blast hole drills- combination?

[amman1]

I am wondering if there is a combination bore hole driller/blasthole driller...maybe switching the hammer from one to another??... If anybody knows of such an apparatus let know. Thanks

Be more specific. Many people use the terms borehole and blast hole interchangably, in which case the only difference could be what's put into the hole rather than how it's drilled.
