By using the OF 1400 router along with the LR32 hole drilling system has saved me hours of time over the last 2 methods I used: a drill and the plastic jig and plunge router. I custom build bookcase units and have the need for a faster and accurate system to make the holes for adjustibles shelves. This system works fantastic. It is quick and will pay for itself fairly quickly in saved time. If you have a need for adjustibles sheving tools and jigs, this is it.Kreg M., North Carolina
