What is the difference between 90° and 108°?

The bit angle sets the groove angle. 90° suits right-angle folds, while 108° suits designs that call for that angle. Choose to match your drawing.

What machine do I need?

Use it with a trimmer or CNC that takes a 6 mm shank. Check your collet before ordering.

The composite V-groove bit has a 6 mm shank and comes in 90 degree and 108 degree versions. It cuts a groove in the back of aluminium composite panels (ACP) before folding them into boxes, corners or sign edges. As the listing says, it gives neat folded corners that do not crack. It is a trimmer-style groove bit regularly used by composite sign makers, giving sharp, tidy folds and saving time on fabrication.
