Eccentric overburden drilling bits
For small-hole sizes, Prodemo produces the PES Eccentric Overburden Drilling System, starting with the ODEX80-P to suit 114mm O.D. casings.
This two-piece system comprises the shanked bit holder and the eccentric pilot bit that is secured in the bit holder by a double interlocking pin.
This is easily removed to allow for bit re sharpening or replacement. Prodemo PES overburden drilling systems are widely used in a variety of applications from well drilling and minipilling to rock anchoring and site investigation.
