When people open up a C-Sert’s pilot hole out in the plant or in the field, usually they are using a mag drill. A big one. A heavy one. It’s awkward to position, and it’s slow. Often it requires an overhead crane or a sling.
The C-Sert System uses a light weight (29 lb) mag drill, a custom 60-degree center for positioning, and hollow annular cutters in place of drill bits.
