Countersink drill bits are designed to create a conical recess in a drilled hole, allowing screw heads to sit flush or slightly below the surface of the material. This not only gives a neat, professional finish but also prevents splitting in wood and improves fastener seating in metal and plastics.
Available in a range of angles, commonly 82° and 90°, countersink drill bits are made from high-speed steel (HSS) or carbide for durability and clean cutting. Some feature a combined drill and countersink design for drilling pilot holes and countersinking in a single step, saving time and improving accuracy.
Ideal for woodworking, joinery, cabinetry, and light metalworking, countersink drill bits are essential for achieving a smooth, finished appearance in any project.
