to the length of the screw.
Step2: Insert the countersink bit into your drill/driver. Please ensure that the drill bit
is clamped!
Step3: Vertical drilling the drill bit during the operation,otherwise the drill bit would
be bended or the chamfer surface is uneven.
The depth only needs to allow the screw head to sink below the surface.
Important Notes:
1. The drill must be kept completely vertical when drilling, so as not to be
uneven.Otherwise, it will be easy to break the bit.
2. Best to use a bench drill,It's not well positioned when using the hand drill which
causes the drill (especially the 3mm and 4mm) is easy to bend and break!!!
3. When the drill bit is damaged, only necessary to replace the counterbore device which
can be used continuously.
