(DLC-SC-SDR)
-Drilling and countersinking holes for screws can be done in one operation, resulting in highly efficient machining (countersink type)
-Since relief holes can be drilled at the same time as drilling pilot holes for power strips, it is ideal for drilling pilot holes in thick panels that require relief (single-cut type).
