Drilling a large diameter hole or expanding the diameter of an existing
hole can often be completed effeciently with a hammer bit hole-opener.
Our hole-openers are available for all standard shanks and are up to 40"
in diameter. Most hole-openers are special order and can be manufactured
in a wide variety of combinations of hole and pilot size. Special features
such as fishing threads, pilot face buttons etc. are also available.
Rotary Hole Openers
Bruce Tool Company builds a variety of hole-openers ranging from 10"
to 72" (254mm - 1830mm) in diameter. Our drilling tools are ruggedly
constructed from heat treated alloys to withstand the punishment of big
hole projects. Our hole-openers are standardly built short, in order to
accommodate rigs with close clearance between the rig and the hole. Extended
upper and lower connections are available to suit the needs of each situation.
To provide the best cost-to-production ratio, our tools are standardly
constructed with rebuilt steel or carbide cutters. However, tools with
new cutters are available on special order.
Our hole-openers are available with a wide variety of cutters to effectively
drill in any formation. For ease of operation, our tools can be built
with any common connection to fit the driller's particular project.
