Fastener removal is achieved by virtue of Perfect Point's proprietary EDM technology, a patented Electro-Discharge-Machining process. Without applying force, the electrode machines a circular cut of desired diameter and depth in the fastener. A closed-loop stream of dielectric fluid flushes the cut and removes the cut debris. Because of the aggressive flushing during the cut, virtually no heat is transferred to the surrounding area, i.e., no recast or heat affect zone (HAZ).

The forceless nature of the cutting process significantly reduces the risk of damage to underlying airframe. Reduction of operator fatigue reduces operator errors. Without "push" force to the drill, "slip" during cutting is eliminated. "Off center drift" at the start of the cut is also eliminated - even on convex button-head fasteners.

Panel damage from "over drilling" is eliminated with an innovative sensing technology that automatically terminates the cutting process when the precise depth is achieved.
