Best used for: Laminate or veneer-finish plunging and dadoing. - Cutting Diameter: 3/8 - Cutting Height: 1-1/4 - Shank Diameter: 1/2 - Overall Length: 3-1/2 - Flutes: 2. 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. Highlights: - For standard CNC milling and routing where a clean top surface edge of material is required - Premium C3 micro-grain solid tungsten carbide for a high-performance industrial quality tool - For use on CNC, table mount and handheld routers - Polished to a mirror finish from a solid carbide rod for precision & accuracy - 2 flute design for MDF, softwoods or hardwoods Item Includes: 1 CNC Endmill Router Bit Down cut CNC end mills are great for dado, pocket and inlay work as well as the final pass on most projects. These bits are especially useful when routing material such as melamine and plywood. Down cut spiral bits are designed to produce perfectly clean edges on the top face of the work piece but since the bits geometry causes the wood chips to travel in a downward direction, which will cause the tool path to be obstructed, it should only be used in applications where the desired finish is required.
