Understanding Hole Openers
At some point it may be necessary to increase the size of a pre-drilled hole to a larger diameter or to drill large diameter holes. Hole opener bits are designed specifically for this purpose. Bits are custom manufactured in a wide range of styles to meet field requirements. A custom hole opener is an effective way of enlarging holes, hence the name "Hole Opener".
There are many variations, all of which are taied to the driller's specific needs. Hole openers can be fabricated with steel tooth cutters, tungsten carbide insert cutters or for Hole Openers, DTH hammers, all either new or rebuilt. Bearing may be open or sealed and the hole opener may utilize either standard or reverse circulation. Hole openers may be the answer to your hole enlargement problems.
TCI(Tungsten Carbide Inserts) Cutters are available along with diamond enhanced features. Fixed cutter hole openers are made from sections of tricone bits as shown left (TCI cutters) and below (Tooth cutters). Steel Tooth Cutters are available with carbide tipping.
Steel Tooth Tricone CuttersToday, drillers are more adept at replacing their own cutters. Your supplier can provide the replacement cutters which saves you shipping the hole opener to and from the manufacturer for repair.
