Yonico CNC Router Bit Low Helix Up Cut 1/4 X 1 X 1/4 X 2-1/2 - 35314-SC

To get a smooth finish in hard plastics like acrylic with your CNC router use a low helix spiral end mill. The modified cutter angle produces a better finish in plastics than standard spiral bits. Downcut bits pull chips downward producing a clean top edge in your parts. Consequently the chips accumulate in the cut path and should be removed to prevent bit breakage. Low helix bits require slower feed speeds than normal high helix bits.
