Three Steps To Use:


Step 1. Rotate the Hex Key to adjust the length you need.

Step 2. Insert the countersink bit into your drill/driver. Make sure the drill bit is clamped.

Step 3. Vertically drilling to the required depth. The depth only needs to allow the screw head to sink below the surface.


Perfect for wood, fiberboard, particleboard, plywood, plastic, PVC, rubber etc. Suitable for bench drill, hand drill and conventional electric drill.


Warm Tips:

1. Must keep the drill vertical completely while drilling! Otherwise, it will be easy to break the bit.


2. When a drill bit is damaged, just need to replace the counterbore device that can continue to use.


3. Suggest to use a bench drill, the effect will be better than a hand electric drill that is not fixed in the operation process, the drill bit is prone to bend and break!
