lack Diamond Bits
Black Diamond is a premium line of
multi-purpose bits, custom designed
for your applications. Utilizing
Application Engineered Cutters and
Engineered Cutter Layouts, Black
Diamond bits can be tailored to meet
the unique requirements of specific
formations and operating parameters.
In addition to new cutter technology,
Black Diamond bits feature a “total
balance” concept. The volume of
rock removed is proportional to the
volume of fluid flow. Other features
like Duraset Gauge and streamlined
geometry make the Black Diamond
line the standard for PDC technology.
