Rougher Up Cut

Three-Flute Solid Carbide Spiral
Roughing cutters are designed for high feed rates on CNC routers in dense materials such as hardwoods and plywood, when surface finish is not important. The rougher bit makes the first cut, followed by a second cut using a profile type tool. This cutter will produce a rippled edge to the cut. It is extremely quiet and smooth in operation, even with heavy cuts and high feed rates. It should be noted that the most common reason for premature wear is insufficient feed rates and worn collets are the main cause of tool breakage.
