Taper Drill Rod

The taper drill rod is evolved on the basis of the overall drill rod. The effective length of the taper drill rod starts from the head of the drill rod to the collar, The length of the taper drill rod from 0.6 meters to 3.6 meters.

There are many factors to consider when selecting a tapered drill rod. We must first check the composition, form and size of the taper drill rod, whether the rock strength, hardness and rock drill strength model match the taper drill rod? If the hardness of the rock is higher, you must choose a more powerful rock drill and a high-quality rock drilling tool with a tapered drill pipe. In addition, it is also necessary to consider whether the degree of the tapered drill bits is consistent with the degree of the taper drill pipe, the length of the top end, and so on. For example: If your taper drill bit is 7 degrees, then the  taper drill rod 7 degree can better match the tapered drill rod 7 degree.

The following are the basic parameters of the taper drill rod:

Taper degrees: 4 degree, 6 degree, 7 degree, 11 degree, 12degree

Taper drill rod Shank specification: Hex19mm, Hex22mm, Hex25mm

In addition to conventional drill pipe lengths, our company can customize product lengths according to customer needs.

Before drilling, it is necessary to understand key factors such as hole diameter and depth, which are related to the success of drilling, taper drill rod and tapter drill bits selection, etc.
