Form countersinking, also known as dimpling, is a countersink that is formed into sheet metal to increase the strength of a structure as the countersinks of multiple pieces nest together. There are two processes for producing formed countersinks: coin dimpling and modified radius dimpling . [ 4 ]
A counterbore in a metal plate. In machining, a counterbore (symbol: ⌴) is a cylindrical flat-bottomed hole that enlarges another coaxial hole, or the tool used to create that feature.
A drill press is a drilling machine suitable for quick and easy drilling of straight holes, countersinking or counterboring that are perpendicular to both directions of a table surface. In comparison, it is more difficult and less repeatable to drill perpendicularly with a hand-held drill.

Countersinking This process is similar to counterboring but the step in the hole is cone-shaped. Boring Boring precisely enlarges an already existing hole using a single point cutter. Friction drilling drilling holes using plastic deformation of the subject (under heat and pressure) instead of cutting it. Reaming
Reaming is the countersinking of a pre-drilled hole, where the tool is supported by the guide pads themselves. Therefore, the tool geometry of these reamers is very similar to single-lip drills. The difference to single-lip deep hole drilling with low cutting depth is the usually missing circumferential chamfer, a long side cutting edge ...
