A compression bit features both up-cut and down-cut flutes, pulling material fibers toward the center to achieve clean, splinter-free edges on both faces—perfect for plywood and laminates. Conversely, a down-cut bit pushes chips downward, yielding a smooth top surface but often leaving rough or torn bottom edges. The primary distinction is how each bit directs chips and fibers, directly affecting the finish quality of the cut edges, especially on double-sided or veneered materials.
