The BTA deep hole drill is a typical structure of the internal chip removal deep hole drill, which is improved on the basis of the deep hole drill in the single blade. The cutting edge has double-sided misalignment, which makes the cutting force distribution uniform, the drilling is stable and reliable, and the deep hole drilled has good linearity. The chips are cut from both sides and enter the drill pipe from the double-sided chip removal holes. The chips are discharged outside the hole, and the deep-hole drilling is performed in the single-blade. The cutting force is distributed reasonably, and it is easier to separate and break the chips.
