125GENERAL PURPOSE DRILLINGAll peripheral indexable inserts in the COMBI-CHAM line are designed with wiper geometry to provide high quality surface finish while DT chipformer ensures good chip control at medium and high feed rates. The drills of the COMBI-CHAM line, in combination with SOGX ...-W or SOGT ...-W peripheral indexable inserts, are mainly intended for drilling large-diameter holes at shallow depths and with short tool overhangs on stable machines.The COMBI-CHAM drills in combination with the WCGX ...-W peripheral indexable inserts were designed for a wide range of machining large diameter holes and offer a clear advantage in the following cases:%u2022 large diameter deep hole drilling%u2022 drilling large diameter holes with long tool overhang%u2022 drilling large diameter holes on unstable machines%u2022 stack drilling large diameter holes%u2022 combination of the above casesground inserts with a wiper and 4 cutting edges ground insert with a wiper and 3 cutting edges
