It is recommended that a straight groove, matching width to the upper part of the T, be cut into the work piece prior to routing the T-slot to reduce the stress on the bit. T-slot cuts produce a lot of wood chips with little room for them to escape and can cause the bit to get bogged down. Go easy on the feed and back off every couple of in. before resuming with the cut.
