The 42mm Split Set stabilizer is a slotted steel tube,with one end tapered for easy insertion into a drillhole. The other end has a welded ring flange tohold the bearing plate.The stabilizer is inserted into a hole slightlysmaller in diameter than the tube, using a simpledriver tool fitted to the drill. As the tube enters, itsdiameter is compressed and the slot partiallycloses. This exerts radial forces along the length ofcontact with the rock, providing the friction which holds the rock together. The driving force of the drillactively loads the bearing plate against the rock. 42mm split set.
