On an advanced aircraft, a repair can hinge on something surprisingly small, such as a fastener holding an airframe panel in place.During maintenance checks on aircraft such as the Boeing 737 and 787, technicians must remove panels to inspect, repair or upgrade underlying structures and systems. Despite major advances in aerospace technology, the methods used to remove the fasteners securing these panels have changed little over decades.
Conventional drilling requires technicians to visually align a drill bit with each fastener and apply considerable force to remove it. Harder alloys such as steel and titanium make the process more demanding. A titanium Hi-Lok, for instance, can take five to seven minutes to remove. A misaligned drill can damage the surrounding aircraft structure, potentially requiring engineering intervention, replacement parts and rework that extend downtime. The process also scatters chips and shavings across the work area.
Perfect Point EDM is modernizing this overlooked part of aerospace maintenance with E-Drill, an advanced solution that uses electrical discharge machining (EDM) to erode fastener material through a controlled, semi-automated process. Across applications, the technology is five to 10 times faster than conventional methods and reduces the risk of damage. E-Drill can remove a titanium Hi-Lok fastener in about 30 seconds—a task that takes more than five minutes using conventional methods.
We’re faster, cleaner and produce less damage to the airplane part. We’re better for the technician, too.
Becker and his colleagues bring close to Seven decades of aerospace industry experience, much of it in structural maintenance, giving them a firsthand understanding of the challenges mechanics face on the shop floor. Their experience has shaped the accessories and tools developed around E-Drill, improving precision and consistency while reducing the force required to remove fasteners. During demonstrations, mechanics often remark that they wish E-Drill had been available decades earlier.
Replacing Force with Controlled Precision
Unlike a conventional drill, which cuts into a fastener using a rotating bit, E-Drill uses a small hollow electrode to erode the fastener material through electrical discharges. The tool is programmed for the required machining depth and width, controlling the amount of removed material.
Accurate positioning is essential. Depending on the application, a technician uses a precision-fit bushing or a vacuum-aligned drill fixture to position the electrode over the fastener. An optical sight helps them center the fixture on the fastener, and specialized alignment tooling supports precise positioning.
Conventional drilling has an error rate of around 20 percent. E-Drill reduces this to less than one percent.
Once the fastener is aligned and the machining parameters are set, the technician places E-Drill in its holder and activates the cycle. The electrode erodes the fastener head to the programmed depth, then stops automatically and signals completion through an audible cue and displayed text. Automated depth control reduces the need for manual judgment during drilling, and controlled operation eliminates the need for the technician to apply the sustained force required by conventional drilling.
Extending Controlled Maintenance to Coating Removal
Fastener removal is one part of aircraft maintenance, while coating removal presents a different challenge. Perfect Point EDM addresses this through S-Blaster, a portable, self-recovering plastic-media blaster designed to remove paint and other coatings from aircraft components.
Engineering Solutions From the Shop Floor
Perfect Point EDM goes beyond supplying tools to understanding client maintenance operations and identifying opportunities to improve them. Drawing on backgrounds in aerospace maintenance, its customer-facing team evaluates tasks in the operating environment and demonstrates how E-Drill can be applied.
“We’re not just pitching a tool off the catalog,” says Becker. “We’re sending the tool out there into the live environment.”
The assessment also establishes whether E-Drill is suitable for the task. If it is not, the team can draw on its field experience to recommend another solution.
Customer support continues beyond the initial assessment and demonstration. A seasoned technician spends two to three days at the customer’s facility, training staff to use the tool and incorporate its accessories into routine maintenance work.
These visits also allow the team to identify problems that existing tools do not adequately address. Customer feedback feeds into product development. As a quick-turn prototyping shop, Perfect Point EDM can develop solutions in as little as two weeks.
A Faster Route to Final Assembly
Perfect Point EDM’s hands-on approach proved particularly valuable for a client that faced a production bottleneck after incorrect parts were installed behind a structure. Before the product could move to final assembly, the client needed to remove 2,000 high-strength stainless-steel blind bolts under a tight deadline. Because the structure was designed to remain part of the aircraft throughout its service life and was never intended to be dismantled, the bolts had to be removed without damaging the surrounding structure.
Each bolt took 30 to 40 minutes to drill out and required several drill bits. After struggling with a few bolts, the client contacted Perfect Point EDM. A capital purchase was not feasible within the available timeframe, so Perfect Point EDM arranged an on-site engagement to demonstrate E-Drill and help complete the work.
Perfect Point EDM worked alongside the client for three days, reducing the time needed to extract each bolt from 30 to 40 minutes to about 20 seconds. Following the removal of all 2,000 bolts, a detailed inspection confirmed that the airframe component had sustained no damage. The client met its production schedule at substantially lower cost and purchased an E-Drill for future use.
“We’re bringing our experience into being the sensei greybeards that people call when they get into a bind,” says Becker.
Expanding Access to Smarter Maintenance Tools
Perfect Point EDM plans to expand beyond its U.S. market to respond to growing international interest. Partnership with the U.S. military is also expected to create opportunities to expand its solutions to NATO allies.
It is helping prepare the next generation of aerospace maintenance professionals through partnerships with organizations such as the Aerospace Maintenance Council. The council hosts an annual competition at MRO Americas, where teams from colleges, airlines and the military take part in aircraft maintenance tasks. As a sponsor, Perfect Point EDM introduces participants to E-Drill and demonstrates its use on aircraft components.
The initiative is an opportunity to share its practical experience with students and guide them as they prepare for careers in aerospace maintenance. As Perfect Point EDM expands its reach and develops solutions to field challenges, it remains focused on improving maintenance efficiency and protecting aircraft structures. These priorities underpin its recognition as Top Aerospace Maintenance Tools Manufacturer 2026.
