Using the Countersink tool you will cut a “V” cut into the surface of the board – insert softhly so you do not bush up the surround of the hole – best is to score the surface then finish to full V cut.
Sand the surface prior to fixing the screw.
Be sure to carefully bed the head into the “V” cut so you get the screw haed flush to the surface,
DO NOT use a rattle gun / impact driver as it is too hard to bed the screw head down neatly.
Best practice is to hand finish for perfect results.
