E-DRILL COLLAR-SIDE
REMOVAL

Perfect Point E-Drill

Collar-Side

The key to the E-Drill process is LOCATION, it’s why our damage rate is less than 1%. For collar-side removal, the collar adapter with an integral o-ring sized according to the collar diameter, is placed over the target fastener. This ensures a mechanically concentric holder over the fastener.
Once the locator is in place, the operator simply pull's the trigger to start the cut process.

For collar-side removal, E-Drill simply cuts through the threads without coming near to the structure or skin, leaving a significant margin to ensure no damage is done to the aircraft. Locator tools are key to the “Perfect Cut” and when used correctly, completely eliminates accidental damage to the structure.

Since we can mechanically lock onto a protruding head fastener, there is no need for vacuum tooling, as is required for flush-installed fasteners. The E-Drill is simply placed over the fastener while the slimline adapter keeps the handtool centered and prevents damage during the cut.

The slimline adapter is specced to propperly locate and align over tightly grouped fastener heads, while maximizing the footprint to enhance perpendicularity. The adapter guides the electrode with an internal guide and seals around the fastener head with a rubber O-Ring.

The metal inserts are removable and are pre-bored to fit specific fastener head diameters. These inserts are supplied pre-bored to a specified size upon request and ensure proper concentric alignement over the fastener head.

Precision Bushing

The metal bushing inside the Slimline Adapter is a critical component designed to precisely fit the fastener being removed.  Its exact sizing helps maintain proper positioning, allowing the E-Drill to cut through the fastener head without causing damage.

Slimline Adapter

The Slimline Adapter is a specialized button head attachment used with the E-Drill system to access fasteners in tight or confined spaces. It features a built in precision bushing and O-Ring to locate and seal over the fastener without the need for a separate locator. Simply place the handtool over the fastener and make the cut.

Hexagonal/Complex Heads

The hexagonal metal bushings for the Button Head Locator (BHL) are ensuring precise alignment for the E-Drill on hecagon head fasteners. These and other custom shape/sized bushings are available and can be machined by Perfect Point to match your fastener spec. Reach out for more ionfo.
