What is an UpCut bit? Up-cut bits allow for rapid cuts since the tool clears the chips away from the material. While Ideal for cutting thicker materials, this type of tool is not recommended for thinner or softer materials. They are more likely to tear the top surface with the cutting edges because they’re pulling the wood fibers up while cutting. When cutting laminated materials, such as plywood with a thin top veneer, that can matter a lot. This type of bit is used whenever the best finish is needed on the bottom side of a part.
