For CNC users, Amana Tool has released new solid carbideĀ CNC compression spiral router bits. Designed for CNC applications with high feed rates that require clean finishes, the bits have a unique geometry that helps to prevent chipout by pushing chips down and ejecting them up during the same cutting pass. Made to cut double-sided melamine, laminated materials and MDF, the solid carbide CNC compression spiral router bits are available in 1/4″ to 3/4″ diameters, with prices for the 1/4″ diameter bits (item #46170) starting at $40.20 and prices for the 1/2″ diameter bits (#46188 and #46190) starting at $80.74.
