3/8" Dia. 2 Flute Low Helix Downcut Spiral End Mill CNC Router Bit - 3/8" Shank - Yonico 36250-SC

List price: $33.95
Short description:
Best for achieving smooth finish on hard plastics.• Cutting Diameter: 3/8" • Cutting Height: 1-1/4" • Shank Diameter: 3/8" • Overall Length: 2-1/2" • 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. 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.
