A major aerospace manufacturing company needed to drill and ream finished holes for the wing skins of their fighter planes in one shot. They asked AMAMCO Tool to help. AMAMCO master tool grinders worked with our customer's engineers to develop geometries for a custom tool that fits specifically into a countersink holder. This allows the operator to drill, ream, and countersink in a single process.
The customer set the goal of 40 holes with a single tool and two resharps for each tool. They pulled the AMAMCO Drill Reamer after 80 holes for resharpening. The consensus was the tool would have drilled 120 holes, but since it had already exceeded expectations by 100 percent, they decided not to risk blowing a hole.
