DES Eccentric Overburden Drilling System

For small-hole sizes, Durpoten produces the DES Eccentric Overburden Drilling System, starting with the DES 90 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. Durpoten DES overburden drilling systems are widely used in a variety of applications from well drilling and mini piling to rock anchoring and site investigation.
