Easy to Use:
Step1: Adjust the chamfering,Rotate the Hex Wrench to adjust the length you need,according 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.
