Yonico CNC Router Bit Low Helix Down Cut Long Reach 1/4 X 13/16 - 32010-SC

Best for achieving smooth finish on hard plastics. Cutting Diameter: 1/4 Cutting Height: 1 Shank Diameter: 1/4 Overall Length: 3 Flutes: 2 Low Helix bits perform a more lateral movement with less upward or downward motion resulting in a smoother finish on single layer materials. These bits are a better choice for hard plastics such as acrylic and phenolic. 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. 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. Down cut bits pull chips downward producing a clean top edge in your parts.
