Deep Hole Trepanning Drilling Tools

Deep hole trepanning drilling head is a tool used for deep hole processing. In the field of mechanical processing, it is used when a hole with a relatively large depth (usually the ratio of hole depth to hole diameter is greater than 5) needs to be processed on the workpiece.Its characteristic is that when drilling, the material in the center of the hole can be completely "trepanned" out in a cylindrical shape, leaving a ring of chips. This processing method has many advantages, such as high material utilization, which is very valuable for some precious materials; and because it mainly removes the internal material of the hole, the cutting force generated is relatively small, and the rigidity requirements of the processing system are not so high, which can better ensure the processing accuracy.
