Controllable depth tapping chuck

In the ordinary drilling machine, the thread depth is difficult to control. For this reason, I designed a tapping chuck that can control the tapping depth. The structure is shown in the figure. First, the wire tapping screw 2 used is fastened to the chuck body 3, and the tapping chuck is coupled to the ordinary drill head spindle through the Morse taper on the taper shank 9. When tapping the thread. The main shaft rotates forward, and the cone handle body 9 rotates, and the cone

Drill Bits

The use of diamond cord core drill bits must be done step by step according to the requirements of the onion, not to be rushed, and the drill tool assembly, deployment, and maintenance must be done well.

The characteristics of rope core drill pipe are "three highs and one low", that is, high drilling speed, long life of diamond bit, high time utilization rate, low labor intensity of workers, so it is widely used in geological prospecting, coal field exploration and other fields. Among the whole set of drilling tools, the most important and most valuable is the drill pipe. The quality of the drill pipe is directly related to the use of the advantages of rope core drilling, and is also vital to the accurate acquisition of geological data and the control of drilling costs.
