Insert The Countersink Drill Bit Into The Drill Chuck
The drill chuck is the part of the drill that holds the bit in place. It is especially important when the drill bit is spinning to avoid accidents. This component has a tightening collar as well as a three-way vice. The best way to tighten the drill bit into the chuck mostly depends on the drill design. However, the common ways are using a chuck key or chuck wrench by hand.

For designs that require a chuck key, you would find an open hole on the chuck for key insertion and subsequent tightening or loosening.  6Pcs Single-End Countersink Drill Set Chamfer Tool Deburring Tool Bits
Additionally, tightening the chuck is fine, but ensure it is not too tight so as not to experience difficulty detaching the countersink drill bit after drilling.

Adjust the Drill to the Right Depth
When you make a countersink hole in metal, the depth and bit type is important if you want the screw head to sit flush with the metal. It is best to set the adjuster to 4mm or more to get the correct depth.
Also, note that the precise depth you would set the adjuster to depends on the size of the screw-bolt head. Using the correct depth would help prevent excessive countersinking (The presence of a gap on top of the screw head) or screw head protrusion from the metal part.  Cobalt Steel Deburring Tool Golden Durable Countersink Drilling Bits Set
