To drill the holes using the peck drilling method, select Use Peck Drilling in the Drilling Strategy area.
When drilling holes you can use peck drilling to reduce chip packing in the hole. The tool drills a short distance into the block of material, and then withdraws to the Retraction Z when the tool Stepdown depth is reached. The deeper the hole, the more frequently the drill must be retracted (or pecked) to be effective.
