Sistem Casing Konsentris
Bit driver lan dering dipasang menyang bit sistem konsentris lengkap sing cocog kanggo tabung diameter 114-1067mm.
Kaluwihan:
1. Ningkatake penetrasi lan perpendicularity
2. Ngurangi syarat torsi
3. Ngatasi bolongan lurus, oblique lan bolongan sudut liyane
4. efek paling karo lingkungan
