Great finish on both sides! If your looking for a router bit that will give you a smooth finish on both sides of your material (no tear out), then a quality compression bit is what you need. Great for laminates! We use only the best micro grain carbide! These bits give a great crisp finish, and they last longer than 2 flute compression router bits on mdf. These bits are good on MDF only and not particle board or melamine.
