ZK2130DB/2500 BTA Deep Hole Drilling Machine For Big Drilling Depth

ZK2130DB/2500 BTA Deep Hole Drilling Machine For Big Drilling Depth

It’s a BTA deep hole drilling machine, which the drilling length is 2500mm length with big diameter ratio. It use BTA drill head,which connecting with drill stem through screw. When drilling the big hole diameter, its efficiency is 2 to 4 times than gun drilling machine. Its usage is wide, but limited by the space of inner hole of drill stem, it mainly used in drilling deep hole diameter bigger than 16mm.
