E-DRILL PROTRUDING
HEAD TOOLING

Perfect Point E-Drill

Button Head Locator

The key to the E-Drill process is LOCATION, it’s why our damage rate is less than 1%. For protruding head fasteners, a locator with interchangeable metal bushings, sized according to the fastener head diameter, is placed over the target fastener. These bushings ensure concentric alignment with the fastener.

Once the locator is in place, it is held steady with one hand while the E-Drill hand tool is used with the other to make the cut. 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 into the locator to keep it centered and prevent damage during cutting. One hand holds the Button Head Locator (BHL) steady over the fastener with light pressure, just enough to seal the O-ring, while the other hand operates the E-Drill hand tool.

The outside diameter and sealing surface of BHL assemblies is optimized to fit between fastener heads spaced per industry standard (typically greater than 4 to1, spacing to diameter), while maximizing the footprint to enhance perpendicularity. 

The metal inserts are removable and are pre-bored to fit specific fastener head diameters. These inserts can be supplied pre-bored to a specified size upon request, or customers can purchase piloted blanks either individually or pre-assembled, which they can bore to their own requirements. Hexagonal inserts are also available for hex-head blind fasteners and the removal of seized nuts and bolts.

Precision Bushing

The metal bushing inside the Button Head Locator (BHL) 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.
