Why does your edgebander chipping melamine on hinge holes? Forstner bits, named after their inventor, Benjamin Forstner, bore precise, flat-bottomed holes in wood, in any orientation with respect to the wood grain. They can cut on the edge of a block of wood, and can cut overlapping holes. For such applications they are normally used in drill presses or cnc drill heads rather than in hand-held electric drills.
Forstner bits have no mechanism to clear chips from the hole, and therefore must be pulled out periodically to avoid penetrating the panels without drilling.
Because of the flat bottom of the hole, they are useful for drilling through veneer already glued to add an inlay.
A major cause of rejected panels is chipped edges on the surface of TFL (thermally fused laminate/melamine) or HPL panels. This is normally caused by a dull 35mm drill bit if panels are nested on a CNC router.
