COUNTERSINKS

Countersinking is done to insure that flat head screws sit flush to the work piece. A countersink produces a conical hole matching the angle of the screw so that when the screw is fully engaged the head will sit flush or slightly below the surface. Deburring tools are used to remove excess material from the edges or surface of a raw, unfinished product and are relatively straightforward to use. Simply slide the blade at an angle along the edge to create friction and scrape away the burrs, leaving a smooth and even finish.
