DTH Hole Openers:
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:
Wear pads, back reamer buttons, and or buttons on the pilot can be added for an additional fee.
The ability to use less powerful equipment than that required to drill the large diameter hole.
All Hole Openers are manufactured from the highest quality aircraft alloy steel.
Straigher holes result from the smaller pilot hole.
Better clearing of cut material.
Jinquan has a large variety of Hole Openers on the shelf, offers a full line of standard and custom Hole Openers in all sizes (from 2 3/4" thru 36") for all industry hammer shanks, and if we don't have what you're looking for we can have one custom-made to your specific application.
