8mm Shank HSS Woodworking Countersink
The countersink drill is used to make the flat head screw head flush with the material or buried in the processed material. It is to be more beautiful and to ensure the smooth surface of the processed material. The drill bit drills a deep hole, so the position of the screw head is aligned with or below the surface of the material being processed. The sharp-edged screw head is buried in the processing material, and the sharp alloy blade can effectively reduce the burr of the hole, and make the drilling more clean and smooth.

What the countersink can do?
You can use a countersink drill, which has a cutter made of carbide around the drill bit that creates a deep cone-shaped hole.
This allows you to drill pilot and countersink holes in one step, and when you drive in a flat head screw, it pulls down into the countersink hole so that the screw head is flush with the surface or hidden underneath.
