💡 What is a plug cutter countersink combo handy for hiding exposed wood fasteners completely?
To cover ugly screw indentations you first drill a precise guide groove with the pilot tip.
- Then swap to the matched sink bit for a deep angled pocket that seats the metal head level.
- Finally slide a matching timber insert into place and sand it smooth for zero gap visibility.
- This routine saves hours of filler work and delivers consistent millwork quality fast.
