Hardness Scale

A hardness points kit is the best tool for determining which matrix would work best for the type of ground that is to be drilled. Each kit includes different double-ended points of varying hardness, stored in a wooden case.

 

The points have all been identified according to the Moh’s hardness scale, ranging from 2 to 9, so that the hardness of the minerals can be identified quickly.

The success of an operation depends on retrieving core efficiently and effectively. We looked at the parts of the inner tube of which the head assembly is a part. It is a complex part so it is well worth looking at it in detail.
