2 Flute Low Helix Upcut Spiral End Mill 1/4 in. Dia. 1/4 in. Shank Solid Carbide CNC Router Bit Set (10-Piece)

Best for achieving smooth finish on hard plastics. Cutting Diameter: 1/4 in. Cutting Height: 1 in. Shank Diameter: 1/4 in. Overall Length: 2-1/2 in. Flutes: 2 Low Helix bits perform a more lateral movement with less lift resulting in a smoother finish. These 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 in.high helix in. bits.Standard CNC milling and routing for challenging materials where material removal and efficiency is requiredPremium C3 micro-grain solid tungsten carbide for a high-performance industrial quality toolUse on CNC, table mount and handheld routersPolished to a mirror finish from a solid carbide rod for precision and accuracy2 flute design for MDF, softwoods or hardwoods
