The Proton QDS self-undercut system is the next generation of undercut anchors to be used in seismic, cracked and un-cracked concrete. User friendly simple in design, drill the hole, position the anchor to the impact tool, then insert the anchor spiraling down the borehole to reach the upper end and create the ultimate undercut, you need to remove the undercut anchor. With the Proton QDS self-undercut anchoring system, no complicated or expensive tools are required; the same tool is used for both applications!
