Deskripsi Pembuka Lubang Tanah

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.
