Perfect Point EDM is an aerospace technology company specializing in innovative maintenance solutions that enhance safety, precision, and efficiency. Founded with the mission to transform outdated fastener removal methods, Perfect Point introduced the E-Drill—an electro-discharge machining (EDM) system designed specifically for the removal of “permanently” installed fasteners in aerospace structures. Traditional fastener removal methods rely on twist drills and manual cutters that are time-consuming, inconsistent, and prone to damaging aircraft components. Perfect Point’s E-Drill system replaces this process with a semi-automated plunge-cut EDM tool that delivers unmatched accuracy while eliminating debris, reducing ergonomic strain, and cutting removal time by up to 20x.
Perfect Point is committed to supporting aviation operators, OEMs, and MROs with tools that keep fleets mission-ready, reduce downtime, and protect high-value assets. Our solutions are designed with real-world maintenance needs in mind—streamlining workflows, improving consistency, and supporting technician safety across the aerospace industry.
E-Drill Fastener Removal Technology
Problem Statement:
The removal of “permanently” installed aircraft fasteners, by manual drilling, is often the most difficult, time-consuming, and dangerous aspect of depot-level aircraft maintenance. Damage from this process to both aircraft and artisans is common and a major cost driver.
Technology Solution Statement:
The E-Drill uses electrical energy to erode fastener head material without physical force, reducing the risk of damage to the airframe and technician. The system includes precision alignment tooling, a closed-loop water filtration system, and simplified controls—making it accessible to both experienced and new technicians. Implemented by both commercial and military MRO operations, the E-Drill has proven itself as a breakthrough solution for
complex, high-strength fastener types, including titanium and blind bolt fasteners.
