V-groove cutters for aluminium composite panel, in 90° and 135°. The technique is specific to the material: rather than bending the panel, you rout a V-groove through the front skin and core, leaving the rear skin intact as a hinge, then fold along it. The angle you cut determines the angle you get — 90° for a square return, 135° for a shallower one. Both are ground for aluminium rather than wood.
