Compensation tool drills and countersinks uneven surfaces without marking

HEULE Tool Corp. has introduced the COMP V3 for multiple drilling and countersinking operations on uneven surfaces with precision, and without marking the workpiece.

This adjustable tool is used for drilling and countersinking or countersinking only. It enhances productivity by eliminating the inconsistency associated with manual countersinking and saves significant cycle time. A non-rotational contact foot prevents any marking of the workpiece during operation, making it suitable for critical fine finishes.

This tool offers chamfer depth adjustments of 0.0008 in. and a 2xD drill depth with through-coolant capabilities.

It can be used for aluminum, titanium, and composites.

Double compensation technology enables fine adjustments. The contact ring compresses as the hole is drilled, and then the contact ring holder compresses after the predetermined countersink depth is reached. This technology allows a variant of part of +/- 3.75 mm with height increments of +0.02 mm.

This tooling includes an adjustment ring, a contact ring holder, a contact ring, and the solid-carbide step drill.

The tool head makes contact with the workpiece, and as the solid-carbide step drill creates the hole, the contact ring moves up. The drill continues working until the preset countersink depth is reached. When the countersink reaches maximum depth, the contact ring holder and contact ring move up together as the drill stays stationary. The drill is then removed, leaving a finished part.

The tool is spring loaded and designed to cut a specific countersink size. Once the specific size chamfer is produced, the face of the tool stops rotation while making contact with the part, and the cutter cannot travel further into the part.
