Reamers with interchangeable tools have been specially developed
for large diameter projects where extending downhole life is
essential. Compared with smaller traditional type tools, larger
bearings and tools can significantly extend downhole service life.
Replaceable milling cutter sets provide TCI and tooth grinding to
adapt to various rock formations. All drills have 3-6 tools and can
be drilled into 4 different sizes.
All tool bearings are metal sealed. The tool lock is used to
prevent the tool from falling off.
