DTH hole openers are used to enlarge the size of a pilot hole most commonly used in industrial applications. Benefits of drilling a smaller pilot hole and then using a hole opener are:

The ability to use less powerful equipment than that required to drill the large diameter hole.

Straighter holes result from the smaller pilot hole.

Better clearing of cut material.
