Technological advances in cutting tools, machine tools and toolholders have allowed machinists and manufacturing engineers to increase holemaking efficiency by eliminating the number of tools required to produce accurate holes. High-performance drills are the best example of these technological advances. In the past, it was common for a machinist to spot-drill, drill and then ream to achieve accurate hole geometry. Now, the same hole can be made in a single operation using a high-performance drill.
