Best used for: Laminate or veneer-finish plunging and dadoing.
Down cut endmills shear in a downward direction causing the uppermost layer of the material to be pressed down against the material just below it. This motion leaves a perfectly clean top surface edge. A concentration of wood chips in the work path will occur. Hose away excess wood chips to prevent bit breakage.
Pros: Prevents top surface edge chipping and tear-away.
Cons: Less than optimal chip removal when dadoing or plunging.
(Choose an up cut spiral bit for standard more efficient milling.)
